Maintaining good car audio know-how
Maintaining audio needs specialized tools
Car audio out of order, should go to a professional car audio repair station to conduct a comprehensive inspection, in order to identify the cause of the disease, the right remedy, and by no means a "street clinic" can be competent. Car audio is different from home audio, circuit design is also more complex than home audio, non-professional repair station or even do not know how to disassemble, and do not know what special disassembly tools. Part of the car owners are sick, looking for some personal or street store repair, the result is that the original problem has not been repaired and produced a new failure; some of the use of second-hand dismantling parts, the price is cheaper, but can not guarantee the quality; there are the use of non-specialized tools, will be prying the car's interior panel bad --- will be the deaf cure into a The first time I saw this, it was a very good idea.
Maintenance of audio to do a "full body check"
Maintenance of car audio not only to check the fault of the sound itself, but also a comprehensive inspection of the vehicle's own wiring, to rule out the impact of the vehicle on the sound. There has been a car stereo radio and cassette part of the normal work, but the CD does not work. Open the host to check the CD control system found burned; continue to check the CD line line, found that 11 lines in 6 short-circuit each other; and then found that the root cause of the failure is the installation of the floor rubber door edge strip fixing screws will be CD line through, resulting in a short circuit. Through the above failure is not difficult to see, only the audio host repair is not enough, but also need to car circuit part of the overhaul, in order to completely solve the problem.
Repair audio to reach the "original standard"
Repair car audio technology content is very high, can not just "repair" even if "fixed", but also to confirm whether the optimal state or the CD cable to wear a short circuit. It is also important to confirm whether the optimal state or the manufacturer's standards. Without test instruments and specialized devices and tools, it is difficult to restore the sound to the original standard. Car stereo adopts highly integrated chips and circuit boards, which include multiple functions in a small volume - a small sparrow but with all its vital organs, and repairers need to have certain technical knowledge and maintenance experience in car stereo. The establishment of a car audio repair station is not a simple matter, the initial purchase of instruments and devices, maintenance information, spare parts, personnel training, experience is also a huge investment; get the manufacturer's authorization, in order to further access to the various models of car audio technical information and original spare parts, in order to ensure the quality of repair.
Precautions for car audio modification
At present, most of the domestic car audio modification is located in the automotive supplies and automotive beauty and decoration stores, and the operation is carried out by a small worker who lacks of experience in audio and knowledge of audio, and who only advertises the brand of the equipment and the price to the owner of the car, so that the owner of the car who was unfamiliar with the audio mistakenly thinks that this is the whole content of the car audio modification. Some modified audio, its effect and equipment performance not only did not get normal play, and even damage to the original electrical system, leaving the owner of the car later safety hazards, many experts pointed out that the key to modifying the car audio is to see if you can carry out an effective error removal, many times, effective error removal is more important than the brand.
Maintenance of sound modification
Car audio due to the special nature of the use of the environment, so that its design is different from the home audio. When people use car audio in daily life, they are not familiar with its characteristics, which can easily lead to some unnecessary failures.
For the car CD audio system, the most attention should be paid to the dust. The laser head is the most expensive and fragile part in the CD, although the car stereo has considered dustproof in the design process, but due to the road conditions, dustproof still need special attention. Careful maintenance of the sound, can effectively extend the service life of the laser head, but also can make the car audio system to ensure long-term high-quality music playback.
Another common problem is the use of CD host mechanical parts. General car audio in the CD mechanical structure is used in the inhalation design, just gently put the CD at the place, the mechanical structure will automatically inhale the disk. And some consumers in the use of this structure, do not understand this structure, mistakenly pushed the disk, which will not only damage the disk, serious cases will also damage the tray structure.
In addition, the warranty is also very important, experts reminded that not all brands of car audio after-sales service is perfect, miscellaneous car audio although cheap, but the cost does not include after-sales service costs, consumers can not just look at the price when buying, must clearly understand the after-sales service status of the brand purchased. Only grasp the quality of the product, master the modification technology, do a good job of post maintenance, can be considered a successful audio modification!
