Car audio installation using surf
Drivers and friends probably have encountered the traffic jam, side anxious as wok ants, but the traffic would not yield over there. At this time, why don't you listen to music? let this long wait as casual good time. Still waiting for? go install car audio!, however, decided to install a car stereo, it is a good idea to understand some common sense, it certainly is useful to you.
Buy essay on driver friend, buy a quality car audio is significantly more difficult. Currently, car audio market profits attractive, many roadside shops technicians mostly without professional installation training, installation of car audio often appear all kinds of failures, to driving a hidden trouble.　　So, how to choose reliable car audio and scientifically installation and effective maintenance? recently, this reporter visited some car audio shop and industry insiders, they draw from three chapters, you can easily have a desirable car audio.　　In the face of the market range, various brands of audio, it is easy to do, how to choose audio in fact there are some basic rules to follow. 1. in accordance with their own taste and affordability and clear yourself of this expenditure of specific costs, because good sound natural to a good price. In luxury cars generally have more professional, with advanced audio products in Europe and America, the sound quality is good, sound more professional than Japan products. However at present Japan some well-known car audio brand also have implemented some fever brand in the US and Europe. Although the performance is good, but the price is really amazing, definitely McCoy, its index will reach the famous brand of value and can be long lasting. If the selection of mid-range audio equipment is not Japan product is, it's the brand in the professional car audio equipment in occupies 2/3.　　Ratio of price and performance value for money and functional completeness and appearance modeling, decoration and technology, sophisticated, and European and American products cannot compete with it. 2. to recognize whether a real brand now markets car audio equipment business in particular, in order to avoid buying back to a set of fake and shoddy products, it is best to look at the business that you have that kind of brand audio equipment manufacturer authorized designated agent license, there is no service capabilities and the quality commitment of the three packages of measures. Another excellent product, nor can it guarantee that the problem does not occur. To solve the car audio maintenance and troubleshooting questions, pay attention to when choosing audio selected audio brands in the local availability of professional certification service repair station.　　Only has a perfect after-sales service of audio brand, can guarantee the car audio system in the event of a failure to get professional, convenient maintenance service. 3. to consider the host's ability to use power amplifier power amplifier for speakers indicated power. Because of the power amplifier is small in long-term use of high power output, easy to burn out, also causes the sound quality is poor, distortion and failure to appear.　　For example: all the speakers indicated power sum to 100 Watts, the power amplifier power to 100-l50 Watts, to have a good match. 4. to understand the speaker's performance in the high-end performance difference between the host will not be too large, the Horn of a staggering difference.　　A trumpet often marked with a few hundred watts of power, making many insiders are mixed up, many of the speakers you can just use the callout 1/10 the power to try out a few minutes, then I'm afraid to maobaiyan.　　5. to hear the sound, sound effects, audition, it is best to find a few spare representative songs, music, percussions, discs, on a variety of sound effects of pure degree for identification, and then determine whether or not to buy.　　6. keep product invoices, the maintenance of certification in order to avoid unnecessary disputes, at the same time protect their own interests, please pay attention to keep product invoice, proof of maintenance. Install article 4 points to be reminded to pay attention to the correct installation of car audio, car audio, home audio system is not put back no longer move. Car traffic, the strong vibration while driving can cause the fuselage jitter laser head can not be normal scan, a jumper or even damage the laser class phenomenon. Therefore, choose which audio shop for scientifically installation is important.　　Industry: car audio, preferably in the same shop to buy and install, this problem is relatively easy to solve. 1. Select a large-scale specialized stores try to choose large car audio specialty store, and they have the strength of the car audio shop brand, renowned car audio brand enterprises generally choose to have the strength and scale of the shop as a product of the specified point of sale.　　Here, the audio display specifications ordered, you can choose.　　2. must have audition equipment if you have basically chosen car audio shop, is about to invade it professional audition auditions for the device or, this is very important, because before installing car audio, it is only through professional audition device to listen, to determine the selected audio quality. 3. be sure to make professional tuning industry there is a saying: automotive acoustics is bought, but rather a design installation. Visible, design installation and debugging in reproducing the importance of the installation process. As a host, several speakers, a few wires, different installation construction workers, would be very different.　　Specialty shop in order to improve the environment, the owners listen on vehicle design science's installation, installed by virtue of a professional test equipment for tuning, make all audio equipment of play to the best effect. 4. the installer must have the credentials of internationally renowned car audio "Sony" and other installer must undergo assessment for "car audio installation certificate" to work.　　Unqualified installation construction personnel will not be able to play the instrument, or even damage to the original vehicle-related equipment. Measures for the conservation of article 5 cannot forget when your car audio purchased and installed, you can enjoy the comfort in your car and melodious music! when you encounter traffic, road, high-quality CD surround sound, a series of rhythm and melody, impatient mood will soon blow over. However, urban pollution and dust is your car stereo's greatest enemies, therefore, you should pay attention to the oftenCleaning and maintenance of car audio. 1. always use a damp cotton swab wipe of small audio in the cassette machine pressure belt pulley and CD player heads are easy to accumulate dust. CD player, the most important part is the laser head, because the laser head is vulnerable parts and more expensive to maintain. Although it is now part of car audio in the design process to consider the issue of the dust, but protection is necessary, you can often use a damp cotton swab wipe of small cassette, cassette and CD-disc slot and a sound system of the Panel. The correct approach is to use the wet cloth dust gently sucking down.　　As for the press and the knob of the cleanup, you can once again use a cotton swab. 2. use the cleanup tool cleaning tapes and CDs in addition to audio hosts kept clean, tape and CD CD-ROM to ensure clean. Tapes and CDs of dirt will not only affect the playback of sound quality, even on the audio damage caused. CD machine head in high speed operation, if you run into dust, magnetic head deviation from the original sound track laser, causing distortion and damage to the head.　　It is understood that the tapes and CDs of cleanup tool in most of the video shop you can buy in. 3. regular checks of tape tension speaker cannot be ignored. It's a grid overlay is easy fouling, the ash can make the speaker volume size reduction. Listen to the music before it's a good idea to check the tape tension, loose will use the pen to its retension; tight will use Rewind way to relax.　　If a tape is not used for long periods or shutdown, the best will tape exit, a long time may cause pressure deformation with wheels. 4. slow clearance less swap discs winter is the car audio with most of the laser head damage, because the climate is dry and prone to static electricity.　　When entrusting his best not to touch by hand directly, don't take intermediate, slowly, try not to frequently change discs, up to the light as possible.　　5. volume do not suddenly drop to maximum audio in use to avoid suddenly put the volume to the maximum, this loudspeaker will burn, coil on the amplifier will impact, suddenly increase the amplitude will be burnt power amplifier.　　When you purchase the above audio from, install to a full range of maintenance to understand, is not the mind at ease a lot of? of course, in the specific implementation process to analysis of specific problems, the only way you can really have a satisfactory sound equipment, make dull driving journey become romantic picturesque and colorful. Warning article five areas to guard against audio conversion, gradually become the car tuning extremely important components. Visit the capital city of several car decoration shop, big or small almost can provide audio conversion services, in order to figure cheap or easy, and many people are just looking for a shop "changed into" results assumed most of the audio is not "good". Where does the problem out, may wish to listen to professionals advise: 1. install a fake or substandard equipment now has a lot of fake brands of audio equipment on the market, there are many domestic brand of audio equipment, neither through technical expertise, as well as with national quality standards.　　Such equipment specifications are very low, the quality is very poor, have the machine on with the noise, while playing music with background noise, this is the signal to noise ratio, is the result of poor quality circuit, but also a security risk. There are some car owners with a lower price to install a set of sound, looks installed equipment, but basically is fake and shoddy products. This equipment is generally no specification, there's no origin and manufacturers, some posing as United States, Japan's brand-name products. Use these products combine sound system, must have noise, music signal is distorted. Furthermore, these product frequency response, in playing music is sure to be a defect, it is not possible to complete the music, especially installed active subwoofer to the overall sense of confusion and even ambiguous.　　Good audio quality is high, mid, bass level, very clearly, like a water pure and transparent.　　　　How to distinguish fake and inferior of Hi-Fi? packaging 1. look at whether there is a detailed description, the place of production, manufacturers, specifications, etc.; 2. no distribution authorization; 3. the key is to issue quality meets equipment indicators; 4. combined into how the system sound effects. 2. installation of the equipment is a low end product is brand-name products, but each brand has a low, medium and high-grade materials, generally low prices are very cheap equipment, such as: simple single-disc CD player with two speakers on the low end, the price is over, looks are brand-name products can easily accept, but this is often easier to abuse by some businesses. Customer only see is brand-name products, and do not know what is low-grade products or equipment does not match between, in particular the low end speakers are even not treble head, is commonly used to support low-power drive, power is relatively small, high sensitivity, volume slightly up will produce distortion when used to complete the CD good sound difficult, mainly treble zone performance worse, Husky Squeaky, bass control is low, and sometimes the "shooting" sound out "flutter, flapping".　　Therefore, consumers purchase must comprehensive test sound indicators. 3. installation of equipment that does not match between is not a brand-name equipment must be a good result, a customer-installed equipment is famous, speakers installed twelve, there are three bass, three amplifier. A not large and noisy, low sound design size calculation also has errors, mainly equipment with unreasonable use of the equipment is improperly installed and debugging techniques is very poor. It is for these reasons, resulting in overall system did not play a role.　　After the match and after installation again, although the basic use of original equipment, sound effects, but new look. A good sound system configuration, is not just a simple mix of money, to give full play to the role of each equipment, mining equipment's potential. Some people believe that the equipment using the same brand, here mention, what is a "fever", not using the best equipment is the "fever", should be using some quality good equipment, but the price is not always very expensive, through rational collocation, professional installation, debugging, make the meticulously equipment to play the best results, more than equipmentThe value of its own, even compared with the effect of brand-name equipment, this is the "fever". 4. installation of technical and technological gap car audio is a semi-finished product, needs to have a car audio professional training of personnel setup in order to guarantee sound quality. Some shops use no trained staff, general installation just put equipment simply concatenated, acoustic positioning error, phase error, adding power amplifier does not install fire insurance, occur. When the installation is fast and does not perform according to specifications of the technology, using wire, crudely, the consequences are poor sound quality, the failure rate is high, the equipment's short life.　　　　The consequences for the sake of cheap is caused when the installation is shoddy work. 5. poor General debugging techniques in car audio industry, the cultural level is low, car audio theoretical knowledge is even smaller, the installation of car audio most people think it is a simple thing, but it is not, if you want to install a good sound system, he should have comprehensive quality and theory with car circuit, electrical theory, acoustic principles, installation technology, music theory knowledge and so on. As the saying goes: "on the ball to Yue, amateur listen to lively," some people think that audio sounds great, bass heavy is good, real good sound is loud when no distortion, and sound permeability level good bass real and not scattered. Some installer even can not read the instructions for use of equipment, will not be using the equipment, not heard symphonies and other real instrument sounds, how to correct the timbre? how can recognize the problem?, how to produce a good sound system, this requires debugging is audio enthusiasts, in tune when the audio system to adjust to the best State. Therefore, debugging is to install the sound system of the last important links.
