As an important part of the sound system, loudspeaker can not be ignored. The grille of the loudspeaker is a place where dust is easy to deposit. As the installation position of the loudspeaker in the car is generally inconspicuous, it is often easier to be ignored. The dust deposited for a long time will reduce the volume of the loudspeaker, so you should pay attention to cleaning.

在音响的日常使用当中，一定要避免突然将音量调到，因为这样做会使音响系统中的电流瞬间加大，可能会将扬声器的线圈烧毁。而且，突然加大音量，也会---影响功放的使用寿命。

In the daily use of the sound, we must avoid suddenly turning the volume to, because this will increase the current in the sound system instantly, and may burn the coil of the loudspeaker. Moreover, suddenly increasing the volume will also affect the service life of the amplifier.

维修汽车音响的技术含量是的，不能只是“修响”就算“修好”，还要确认是否达到状态或厂家规定标准。没有测试仪器及设备和工具，很难将音响恢复到原厂标准。

The technical content of car audio maintenance is correct, not only "repair sound" even if "repair", but also to confirm whether to meet the state or manufacturer's standard. Without testing instruments, equipment and tools, it is difficult to restore the audio to the original standard.

汽车音响多采取高度集成的芯片、电路板，在很小的体积内包括多种功能———麻雀小但五脏全，修理人员需要具有一定的汽车音响技术知识和维修经验。

Car audio adopts highly integrated chips and circuit boards, which include multiple functions in a small volume -- sparrow is small but has all five internal organs. The repairman needs to have certain technical knowledge and maintenance experience of car audio.

成立汽车音响维修站更非简单的事情，前期购买仪器设备、维修资料、零配件，进行人员培训、积累经验的投入也好；得到厂商授权，才能进一步获得各款汽车音响的技术资料和原厂配件，才能更好的维修质量。

It's not a simple matter to set up a car audio maintenance station. It's better to buy instruments and equipment, maintenance materials, spare parts, train personnel and accumulate experience in the early stage; Only with the authorization of the manufacturer can we further obtain the technical data and original accessories of various types of car audio, so as to achieve better maintenance quality.
