Ktv sound more often only know to appreciate, but have forgotten how to install, because the installation is not good, the overall effect of that sound will not be perfect, install audio also need some tips. Like to share with you the next Xiaobian 6 Click Install the sound you need to know!
An electronic device, otherwise it will malfunction. There must be specially trained personnel to install, in order to ensure security.
Disassembly technology: audio-conversion process, the original car stereo removed, whether disassembly is a modification of the fundamental problem, because now dashboard surface can not see the screws, so it is necessary to pry open the decorative parts to see the screws, the demolition operation requires professional and strict, or easy to dismantle bad. The second step, a wiring, dress speakers, it is necessary to removable door panels, door, dashboard, seats, decorative plates, in the disassembly process, the need for special tools, to keep the original intact, otherwise it will not pretty and sealed well to produce noise.
3, whether the product is qualified: many counterfeit brand-name equipment, at the time of purchase must distinguish now on the market, otherwise no end of trouble. Some inexpensive equipment, from the appearance is not out of the quality problems, however, the inner components are inferior, the circuit is designed to not meet the standards, poor sound quality of this equipment do not say, it is prone to failure. even produced naturally. Must be factory authorized shops to buy, to ease of use.
4, how the sound quality? Not buy brand-name products will certainly be nice, brand-name plant varieties can be divided into high, medium and low grade buy is not necessarily nice, the most fundamental work by a professional system, installation and commissioning, to good effect . Not a simple matter of a few lines casually connected, the sound field positioning, phase can not be wrong, otherwise the effect would be disastrous.
5, taking into account the after-sales service: car audio is in motion, environmental degradation slightly, such as: temperature, humidity, vibration, dust, easy to make the sound to produce a variety of failures, maintenance, warranty and maintenance is a very important issue. Cheap parallel imports to buy, renovate and clearance products, theft machine, the warranty card is false, there is no after-sales service, once the damage need maintenance fees, or scrap, whether it is worth. Now store the sale of the equipment is not necessarily expensive, a lot of cost of good equipment, you can enjoy good service, why not.
6, the installation environment: installation of some shops in the open air, and the staff\\ s uniforms dirty, sound installation finished, but the interior of the car and the car looks dirty. Buy a new car sound change is a good thing, but to bring many negative consequences, is a sad thing. Specialty store in the indoor operation, and its benefits, clean, and ensure the car clean inside and outside. 2, independent of temperature, easy to damage when the temperature is too low when the demolition of plastic parts. 3, protected from the weather, rain, wind can work properly. Because of the lighting, so during the day, black day will work. 5, the customer has a good lounge.
These are the professional and non-professional technical difference, this is also the difference between high and low price of non-professional, and ultimately is a value concept, is to choose the price or option value. Do not install the audio as it is an easy thing, not a line to connect audio ring on the bin, not only the sound quality does not guarantee, as well as adverse factors and pitfalls in which, therefore the emphasis to go to a specialty store installation, can be guaranteed.

Drivers friends probably encountered traffic jams, here anxious as ants on a hot pan, but the traffic there motionless. At this time, why do not you listen to music? So that the long wait for a casual good time. So what? Quickly to install car audio now! However, before you decide to install a car stereo, it is best to first understand some of the relevant knowledge, which you certainly are useful.
Purchase of articles
Friends of the driver, buy a quality car audio there is very difficult. Currently, the car audio market, attractive profits, many roadside shops are mostly without professional installation technician training, installation of car audio often a variety of failures, to traffic safety hidden trouble. So, how to choose rest assured that the installation of car audio and scientifically, effectively maintain it? Recently, the reporter visited a number of car audio shop and the industry, they remind you start from the three chapters, you will easily have a Heart of car audio.
Face of the market an array of various brands of sound, very easy to know what to do, how to choose sound there are some basic rules to follow.
1 according to their taste and affordability may be
This is a clear understanding of their specific expenditure is the cost, because a good sound natural to have a good price. In the high-end luxury cars generally have more advanced professional audio, in which European and American products better, the sound quality, sound more professional than the Japanese products. But now some well-known Japanese brand car audio brands have also introduced some of the fever to compete with Europe and America. Although performance is good, but the price is really amazing, definitely the real materials, to achieve its target value listed on the nameplate and long-term sustainable use. Mid-range audio equipment such as the selection is none other than non-Japanese product, its brand in the professional car audio equipment accounted for 2 / 3. The ratio of price and performance value for money, and from the functional completeness of the shape and appearance, decor and sophisticated technology, etc., but also in Europe and America can not compete with the products.
(2) to recognize whether it is really the brand
Now on the market for vehicle audio equipment businesses particularly, in order to avoid buy a fake and shoddy products, the best depends on whether the business owns the brands of audio equipment factory authorized designated agent license, whether the service capacity and quality three bags of commitment measures. Another excellent product, we can not guarantee that the operation will not be a problem. To address the conservation and car audio troubleshooting problems in the purchase of sound mind when the selected audio brand in the local service professional certified repair stations. Only with perfect audio brand of service in order to ensure the car\\ s sound in the event of failure to be professional, convenient service.
3 to consider the ability of the host amplifier
Try to use the power of the amplifier is greater than the speaker instructions. In the long-term use because of the small high-power amplifier output, easy to burn, can lead to poor sound quality, distortion and other failures. For example: the sum of all the speakers indicated power of 100 watts, the amplifier power to 100-l50 watts, in order to have a good match.
4 To understand the speaker\\ s performance
High-grade will not be much difference between the performance of the host, speaker of the difference is amazing. A speaker at every turn marked with a few hundred watts of power, many insiders are confused, many speakers you just use it to mark the 1 / 10 the power to try a few minutes, I am afraid will be exposed to a white smoke.
5 To listen to sound, sound effects
Listen, it is best to find several dishes representative of the songs, music, percussion and other discs, the pure sound of various degree of identification, and then determine whether to buy.
6 keep good products, invoices, proof of maintenance
In order to avoid unnecessary disputes, and protect their interests, Take good care of your product invoice, proof of maintenance.

Mr. Zhang reflects the people: I live in Tongzhou District, near the west gate, usually always hear the mini-bus air horn sound harsh,
affecting normal life of residents. What can reduce the speaker volume?
Re: Beijing Hi-Tech Co., Ltd. Operations official said the passenger, the company removed all vehicles from last year s air horn, and is
equipped with "electric snail" type tweeter vehicles, the replacement for the 105 db within the normal speakers. If you still find people
using air horns of the Henderson passenger vehicles, can remember the number, call the company telephone 69591016 to report
complaints.
After receiving the reports from the public, by Henderson s passenger lines, check-by-site passenger car horn, found 220 passenger
vehicles, there are 11 privately install the air horn, the company has removed them, punished and made to give the owner education.
Our reporter Li Yan
Western Hills forest area will be the installation of temporary street language
Wu reflects the people: I am Paul Leisy mountain language district property owners, stay almost 3 years, but the district one, two
have not been installed between the street, the dark night, hoping to install street lights.
Re: Paul Leisy mountain language community Poly Property Management (Beijing) Co., Ltd., said district one, two for the road
between the building developer collected on behalf of the municipal road. City street last month, the property management center to
report installed. Thus matter involves street repair and maintenance and lighting costs, not the formal planning and design of street
lights installed in the short term.
Currently, the property is contact the developer, the first in this section to install temporary lights on road safety issues.

Car Audio Tips
The reason can be called a car audio system car audio, the most basic condition is that – there are sound playback capabilities. Car audio system, must contain at least the following points to be eligible as car audio, car audio systems that are any natural.
1 Software and the Media: What you want to listen? Traffic conditions of the program? Then you have to open radio stations, and transferred to the correct channel. Want to watch TV in the car? It is more simple, the LCD screen has long been one of the leading car audio systems, and even if you want to see DVD is the same. Listen to music? Your favorite album put a bar, whether it is CD, MD, cassette, which is just inside the singer s collection of songs, you like Liu Jialiang, I want to hear Hit-Pop, who put the album will come to hear it, buns bread differ from each other.
2 source: Multimedia software can decode the body, that of the source. This terminology may seem difficult to understand, in fact, very simple thing! Broadcast radio tuner called, commonly known as the radio; play called cassette audio cassette seat; The play CD album, called CD-Player, but also for compact discs – easy!
3 pre-signal control: Simply put, the first level is the level in the post, we will generally be called after the amplifier stage, so in between the sound source and amplifier, all the parts for the music signal processing, are known as pre- . For example, the host car audio volume control, is part of belonging to the former class, which controls the signal strength is the degree. Other audio equipment, the more often see some of the top-level control, as well as treble and bass adjustment, left and right balance, before and after volume adjustment, and Loudless loudness control. In addition, there are more complex audio equalizer (EQ), its function and bedside sound often seen with multi-frequency tone adjustment, the screen will display a different pattern of the same functionality. In addition, the digital sound processor (DSP) is now standard on many hosts, simply to say that simulate sports, dance or concert hall the sound features such as space. All in all, all about signal processing or adjustment of the institutions of the former class.
4 power amplification mechanism: the first level control most of the voice signal intensity are only a few volts, enough to drive the monomer (see section 5), so the signal must eat, \"Dali Wan,\" so that the signal strength stronger, so that it can watt (W) to calculate, so the success rate of the output signal to strengthen institutions, called the power amplifier, which is commonly known as the amplifier. In general, the total car audio system output value, which is all the amplifier system and the output power, have been used as a car audio system in the size of the series on the classification.
5 Speaker: mechanical sound waves into electrical energy is called the speaker. Perhaps the reader has to guess the speaker is commonly known as the horn! Right … … only half the story. Can signal into a sound body, in addition to the general common round or oval back and forth to the moving coil speaker monomer, there are other types of speakers! For example, with the sound of metal ribbon type (Ribbon), driven by electrostatic diaphragm planar electrostatic speakers, are also in place in the audio. But in car stereo moving coil speaker is still the mainstream, the impression that in addition to the United States and Taiwan EVIL Infinity-style vehicle with ribbon tweeter, other are common moving-coil monomer.
6 transport sector: a complete car audio system, a combination of wire components is essential, but the wire is often easily overlooked. In fact, wire good or bad, will directly affect the sound quality, because the wire from the material, stranded structure, the diameter of the insulation resistance value with the specifications on the design and so different, will affect the signal or power transmission. In the use of wire, due to the different needs of different equipment design-oriented wire, such as power, ground, start signal, horn, fiber and wire required for a particular system, are due to their different requirements on the design the difference. For example, the sound quality of speaker cable required, the purity of the material must be as high as possible, otherwise too many impurities will affect the sound full play. In addition, between the wire and terminal equipment is also very important contacts a solid or not, the contact area the size of the joint design and material, and ground is good, will have a significant impact on the sound effects.
Among the host is currently commercially available, many already have a source, pre-and post-class, include the audio form the basic structure. Why do I say? You see whether the host has single-disc CD, tape deck or radio? At least one of the different bar! That is, source friends. Look at car audio host, is not the size of the volume can be adjusted, but even the most low-end host has to adjust the treble and bass sound right! That is a first grade. In addition, the host is not there most of the output power it? If the car audio system, the speaker is pushed directly to the host, then the host must be included in a power amplifier, such as the common modified the original host or hosts will have most of the power output. The host did not have a built-in power amplifier with output, commonly known as the host of this dumb machine, only the signal output only. Do not think that the host would be more expensive, in fact, most of the dumb machines are among the most advanced flagship, as it will use the dumb machine will be installed car audio amplifier, so the internal parts of the host material is more advanced, the line structure of the walk more complete, so the price is also the most expensive!
Aspects of the power amplifier, if accompanied by sound adjustment, electronic crossovers, equalization, or other functions of the model parameters, it contains pre-and post-class two parts, that is, multi-purpose amplifier; if only purely for power amplifier the aircraft, that is only part of the after-class. If it is the speaker? Needless to say, after it is pure class. Even includes a passive crossover, only tailored for the speaker components, although it is also a control signal frequency and tone adjustment, but it still belongs to a part of the speaker system. Next time you see any one car audio equipment, you can self-analyze it! Car audio system size is, some people will think that his car filled with car audio really simple, and so it can be called the car stereo? I think if you complete the above conditions, you can specify the issue or you want to hear the sound, it can be called car audio, even if the host with the original equipment is only a few speakers. Conversely, if a there are several sources, many of the large Department of amplifier volume control system was not able to listen? If no speaker can sound it? Even if such a system the size is bigger, more equipment, do not be a car stereo.
Little careless car audio conversion
The size of car audio systems, depending on the individual requirements for sound quality. Whether your car sound system the size of the car, next time when you open the car s sound, as long as you want to listen to the music provided for your listening enjoyment services, is the most perfect car audio system.
But when you select a sound, the best brand to buy a package, it will not only have quality assurance, and product specifications must be very detailed and will guide you how to properly use, will avoid the embarrassment of using the wrong .
car audio characteristics of the host audio signal output
In the car audio field, now the most used way is to output the analog signal output, such as built-in amplifier to directly drive a small
speaker, but also the first low-level signal output to connect to an additional power amplifier. Analog audio preamp output is used in
car audio red and white RCA connection, the connection of other audio / video products are more common, but in car stereo, the
two colors represent the analog audio signal input and output, and almost all of car audio products, and are based on the RCA
connections, including equalizer, power amplifier.
The output analog audio signals, there are four types: single-point grounding type, balanced, floating and differential. This is the
original car audio systems and after-market car audio compatibility is a very important key. Usually a type of audio output can not be
compatible with another, even though they may choose the same RCA connectors. Many after-market car audio and video host of
audio signal output is very simple, it is a single-point grounding type. High output of the host that drive speaker directly, its output is
the use of floating. But the original car the host are generally in a balanced output or differential output, which is after-market audio
products have a greater difference.
Some High-end level of the host or CD disc CD box with digital audio signal output, the DVD host, digital audio output but also a
standard. The digital audio output must be D / A digital-analog conversion, the digital signal into an analog signal, then output to the
amplifier. Now, there are several little-analog converter to power amplifier to receive digital signals. Hosts the DVD, the digital audio
signal output decoder will also require the use of multi-channel signals into separate channels.
The output of digital audio signal output method is commonly used fiber optic signal output, it uses POF (plastic optical fiber cable),
and analog signal output by the use of copper signal lines are completely different. Optical digital audio signal is converted to a signal
light pulse signal, it is not all finished inside the electromagnetic interference. Fiber connections of copper wire and other differences in
the way, to ensure signal purity, optical fiber signal can not bend over so as not to have an impact, especially in fiber length and fiber
optic cable production methods, are required to take into account optical signal transmission. Of course, the use of fiber optic audio
signal processor also requires it, and then the optical signal into an analog signal. This input is very common in the civilian market, but
relatively rare in car audio. Fiber-optic signal connector commonly used to connect both ends of the head with a standard TosLink fiber
cable POF, this connector is designed by Toshiba Toshiba and named.
Digital audio signal output connection is also used in coaxial signal output, similar to its Connector RCA connector, the difference is
between them is the use of one-way coaxial system, the digital audio signal transmission to the D / A converter, in order to match
between the equipment, the use of RCA coaxial connectors, the standard should be 75 ohm coaxial cable shield, and only one wire,
braided shielded cable is out.
Technical points of the host audio output
Audio audio output to the host they connect with the equipment to match its technical points are worth our attention, they are
related to the performance of the entire sound system. Main points are:
1, the signal to noise ratio S / N Ratio
This parameter is the source of the sound system for the entire system to produce heavy burst of new noise ratio, and its noise are
thermal noise, communication noise, mechanical noise, and so on. The indicators for the general detection of rated output power of
the playback signal with no signal input system noise output power ratio of the number of decibels (dB) to represent. The higher the
better the audio signal to noise ratio, the higher signal to noise ratio of equipment that it produces less noise. Such as CD players up
to 90dB signal to noise ratio above, high-end even reach l10dB more.
2, pre-output level
Pre-output level is a very important parameter, because it will affect the audio chain, the lower product-related parameters. It is given
in volts. Output from the host level or at least the processor in the power amplifier input sensitivity adjusted to the lowest, nor will
they produce overload distortion, sound system will not produce the slightest sound. When the sound system is used to hear voices
or music, the host of the amplifier output level and input level of the best ratio is 2:1, that is, if your host s maximum output is 4V,
then you The maximum power amplifier input level best to 2V. In any case adjustment, the best match is the power amplifier without
distortion, maximum power output. Despite the higher output level of the host, it seems that the more power amplifier can drive, but
in reality, we must consider the level products matching the input sensitivity. For example, the amplifier s maximum input level is 2V,
then the output level is not appropriate host 8V.
3, the output impedance
This parameter is considered connected to the host with the lower equipment matching issues. Output impedance is the ohm units.
The actual output impedance varies with frequency, so the nominal output impedance is actually based on a specific frequency
measurement results. In general, the pre-output impedance ranges: 50 Euro to 1000 Euro. Generally considered to have low output
impedance of the host is excellent, but in fact, this also represents a large current output. The advantage of high current or power
amplifier connects multiple processors. When connecting a single power amplifier, then the size of the output impedance is essentially
no difference, but when connecting multiple amplifiers, and a Y-shaped sub-line, then a low impedance high current output level
before the host is the best choice . In practice, make a sound pressure in the car, preferably in such a low impedance of the host.

Car DVD audio why so weak – an engineer is view
Why made DVD sound so bad?
I work in car DVD solutions company, but also be mixed in the car audio circles for five or six years. As an electronic engineer and HIFI
enthusiast, it is clear why China-made car DVD sound so bad.
Here I analyze one by one, said the wrong places, please forgive me.
1, the root cause: interests.
In addition to flying still a good song sense of sound (only in the sense, after all, is the people playing this card), the other solutions
company and manufacturer, there is no sense of sound, or will turn a blind eye.
Shao is very clear sound this stuff, I will not speak tech, just material costs, the relationship between sound and cost is not linear,
but logarithmic relationship. Simply put, you pay a dime half cargo, cargo-third of a dollar.
We all profit-driven industry, especially in such a Fuzao era. Manufacturers would not willing to increase the cost to upgrade the
sound quality so much, people in pursuit of the “cost” (profit).
2, the main reason: consciousness.
Over the years the DVD industry is so made came to be, we have become accustomed, and in accordance with the inertia to
continue. They (the manufacturers and solution providers) that the car on the environment, as there are several owners is golden
ears,
Big deal a few people do not do this business. Without customer demand (driven by the interests), program the company will
certainly not take the initiative to do this a “meaningless thing.” Moreover, not so many years of accumulated technology in this area,
to make sound
Simply no place to start (the current program the company is crazy for a few audio IC!), Comfort is the heart is finally being tried by
people.
Meizu boss J. Wong said this: “Good chip components may not be able to create a good product, but certainly not a good chip
components can not produce a good product!”, I agree with his words.
3, the industry direction: functionality, cost.
Clearly the direction of the industry, growing on the function, whether useful to useless, because the more functions, the product
highlights (selling?) Is also more. Furthermore, the cost is now the industry has
Into a full buyer s market, upstream manufacturers in order to seize the market, desperately costdown. There are several industry
leading companies of the serious quality accident (that did not sound returns, tentatively called recall it), because COSTDOWN caused.
Have demolished a car amplifier, above 7 3300uf/25V capacitor (same size), even with the four brands, production dates vary from
number to see the first 90 years, a look and silent. Car DVD material fact not much better.
4, the underlying reasons: the user and business conflicts.
In fact 90% of users are not really “wood ears”, are able to hear the good and bad, they want to sound better. Why has no one to
meet them? – Interests, the interests of dealers.
Although the experience of ten years of development, but the industry is still chaotic, good things are hard to marketing, customer
acceptance to pay for marketing costs are too high, no one wants to do this thing. They stock mainly to see which brand of cheap,
easy to sell.
5, nonsense: countermeasures.
Someone (this person must have the capital, channels, influential) points out to do this. Japan s top source is a small change in the
dominance of CD.
to the host or amplifier input level GAIN LEVEL debug tutorial to teach you how to tune a good sound system
CarCAV modified car stereo school:
“Input level” This is a modified car stereo in a very sensitive jargon, but a large part of car audio conversion technicians are
collectively referred to as “gain” or “volume.” In fact, the latter two is entirely wrong, in fact, “input level” refers to the host state of
the maximum undistorted output level, transfer to the power amplifier, power amplifier output level corresponding to host matches,
and then amplified output to the speaker. “Input level” is just a transfer from the source to the amplifier stage or auxiliary devices of
the matching process, then why in the amplifier GAIN or LEVEL rotary knob in the size of the speaker sound will change? Level
because it is matching the size of the voltage change in the size of it, it s the size of the sound output level in the match after the
host will not increase after the matched power amplifier distortion level is amplified if so, would have hurt the speaker unit We said
after the match level amplified voltage amplifier clipping. Clipping of a sound system is fatal, not only will make the system noisy, but
also make sound bad, heavy speakers will be destroyed, so a little affected by the input level range is very wide, then how to adjust
the input level?
First you need two things: 1, oscilloscope; 2, signal test disc (with a 1KHz 0dB,-5dB, +5 dB signal such as discs, the discs used in this
chapter is to post to the signal blessing 3Sixty2 disc), then the following the steps.
The test consists of CarCAV technical director Hao child and Guangzhou lion and dragon, CarCAV technical director Yuan Huaqiang
together to complete! Test equipment such as CD players and amplifiers brother fat boy from Guangzhou to provide outstanding
pioneer DEX-P99RS and Alpine CDE-9872E!
Tutorial before the start of the oscilloscope is the first to explain what, according to the name can also think of their role in it, is to
test and watch the signal waveform of an instrument, a place where we can see with your eyes is not a distortion of the signal
equipment.
If the test disc is the source for the oscilloscope prepared by the host broadcast of the corresponding signal oscilloscope for testing
and viewing the image, in fact, we often use the signal is 1KHz 0dB, then the child should also mention that for the ho-5dB and +
5dB? The-5dB is used in the bombing machine, in the American habits, in order to achieve greater sound pressure and adjustment, of
course, use this signal to debug, then there will be distorted, but the bombing is certainly a distortion if the signal , just to grasp the
degree,-5dB is a good degree; +5 dB is generally used in Europe, the game s more, Europeans not Americans demand more bass so I
use this signal, but the Europeans +5 dB for our Chinese people, a little less, in fact dynamic enough, so we use 0dB signal, of course,
we can match according to different needs and commissioning of the input level.
modified model high-power sound system modifications Cherokee
Cherokee is a family of loyal love of cars out, for its power and manage off-road, the car s sound policy motives larger damping function
should be worse than the car, but from the perspective of sound placement, it internal space, body stability, and good listening
environment, so this model than the power of properly manage the placement of high-power sound system. other, so the overall
sound system and environment models also more appropriate.
In the specific modification of this model, we should, where appropriate, to the point that many users prefer this model a sense of
fast beat music. Well, according to the characteristics in the choice of sound system should note the following aspects:
1, there must be sufficient output power, in order to progress signal to noise ratio.
2, the promotion of bass, to cover the loss of bass due to noise.
3, the sound pressure to focus on results, because the dynamic scope of a large dynamic music, volume high.
4, the door should be reinforced to reduce resonance. Here we have to listen to “disco”, “rock” as the main purpose to select the
sound system to give two kinds of modification master insurance program.

Subwoofers U.S. MOHAWKM1212 inches, the maximum power 180W, sealed speakers manage, black velvet jacket, impedance 4Ω.
Placement of another way
Straight for the host instead of the original car s cassette players can be.
Speaker mentioned that the speaker, I would like to clarify it. To deal with the car, the results in order to sound good, the best
choice for large speakers FireWire, because the original car used in the front door is 5.25 inches below the speaker, the impedance of
8Ω, power 20W, not with the treble, if the original car speakers, power sector will be lost first, because the amplifier output
impedance is 4Ω have the following, so when the load impedance 8Ω output power will be reduced twice. Secondly, the treble will
lack, and the location is in the bottom of the front door, listening to the subject aims to come from the bottom To handle this
problem, the arrival of nothing, is the largest sub-body suit speaker. more ambitious resettlement program is to use two, 4 and 6
configuration, that is 2 inches treble, 4 inches, 6 inches in the bass tone so the purpose is to configure the frequency response curve
with a more smooth convergence, mediation and easy school, but this practice placement complex process, if necessary, reinforced
door, the adoption of sound-absorbing the pace.
Specific speaker placement of another way as follows: front door speaker placement will be reaming, and then placed 6.5 inches
above the midrange speaker, tweeter placed in the upper triangle at the front door, this is intended to parallel the human ear height,
form good listening angle. crossover placement is required within the door. M6 rear speakers should be placed on the baggage door.
subwoofer should be made of inverted-phase system, the purpose is to increase the bass volume to progress playback to obey in the
placement can be placed in the car after the luggage compartment, so you can at any time in accordance with the environmental
movement of goods, if the fear of other objects collide, the subwoofer can also install nets.
Electronic balancer electronic balancer placed in the bottom ash box FireWire host site for easy adjustment at any time. Electronic
balancer role is to mediate, respectively, treble, tenor, bass, also the content of the music itself, like the differences and the flexibility
to mediation music curve. 5V output progress signal to noise ratio, and has AUX input interface can be outside Walkman MD, MP3 and
so on.
Multi-disc CD multi-disc CD drive, drive on the right side placed in the trunk after ah, placed in this position much space, it also can
reduce the vibration impact.
Power amplifier it is a sure way of placement of 10mm thick MDF, in accordance with the shape of the back seat through the back to
do a backplane, using the back of the amplifier and the body can make the purpose of insulation, so wiring can be standardized and
then wrapped in wool , and then placed in the top two power amplifier and finally by the rear seat on a smooth, you can recline the
seat back does not affect use.
After placement of the various departments of the work is to connect them, the connection between this sound is: Sony XR-CA640X
-host electronic balancer – put enormous power device CA-550 and CA-100, 2 个 power amplifier CA-550 to promote the M6 and M62,
CA-100 to promote the Hawk 12 inches subwoofer in connecting the various departments, pay attention to the selection signal line,
in order to guard against interference is best to use double-shielded power cord, according to the current big and small thickness to
the resolution, but also is cross-sectional area to choose antioxidant speaker line.
The progression-based audio system features, treble Huo Liang, bass shock, but spare to listen to pop music.
