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.

在音響的日常使用當中，一定要避免突然將音量調到，因為這樣做會使音響系統中的電流瞬間加大，可能會將揚聲器的線圈燒毀。而且，突然加大音量，也會---影響功放的使用壽命。

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.

維修汽車音響的技術含量是的，不能只是“修響”就算“修好”，還要確認是否達到狀態或廠家規定標準。沒有測試儀器及設備和工具，很難將音響恢復到原廠標準。

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.

汽車音響多采取高度集成的芯片、電路板，在很小的體積內包括多種功能———麻雀小但五臟全，修理人員需要具有一定的汽車音響技術知識和維修經驗。

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.

成立汽車音響維修站更非簡單的事情，前期購買儀器設備、維修資料、零配件，進行人員培訓、積累經驗的投入也好；得到廠商授權，才能進一步獲得各款汽車音響的技術資料和原廠配件，才能更好的維修質量。

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.
