Is there anything to talk about car maintenance?

Car audio maintenance is different from ordinary household appliances. Due to the harsh use environment, heavy dust, large vibration and small compartment space, the car audio can't be too big. Usually, the standard size is 1din: 182mm * 53mm. In such a small space, the heat dissipation of the main engine is also a problem, which determines that the car audio must be durable. In order to adapt to the limited space, car stereos mostly adopt compact design, such as miniature patch components and double-layer circuit boards (some of which use multi-layer circuit boards). Every electrical failure has its own reasons. Some faults are inevitable, and the design of the machine itself has a service life, such as the CD laser head, which will age with time. The main feature is that the CD reading ability is getting worse and worse. When the laser head is aging, it must be replaced. Some faults can be avoided. To maintain the good performance of the machine, we must develop good usage habits. Bad usage habits will only accelerate the damage of the machine. I once knew a car owner who probably liked strong music very much. He likes to turn the volume of the stereo to the maximum, even if the music is seriously distorted, as long as the volume is loud enough. I don't know. This hobby can easily hurt the sound system. The speaker bears the brunt. The speaker has good pronunciation characteristics in its power range, but beyond the power range, the distortion will rise sharply and the voice will be hoarse seriously. The power of the speaker can be very high in an instant, but it cannot be in a high power state for a long time. When the power output to the speaker is greater than the bearing power of the speaker, the excess energy will be converted into heat. The high heat emitted cannot be effectively emitted, which will cause irreversible damage to the speaker. Car stereo is a set of sophisticated electronic equipment. Although it has a perfect design, it should be used with care. Whether the car stereo is durable, whether it can give full play to its functions and the installation process are also very important, which is one of the reasons why the car stereo is different from ordinary household appliances. A senior car audio installation technician, he is not simply installing wiring, he will consider whether the various systems of the audio are matched, make appropriate suggestions, and try to install with the best configuration. Some irresponsible technicians install it at will, and the wiring will not strictly distinguish between positive and negative phases. Even a set of high-grade audio they installed can only produce mediocre sound effects. It's best to go to a store with strong technical strength to buy a car stereo. After all, car stereo is not easy to install, and after-sales service is also very important.
