之所以寶馬汽車音響維修的價(jià)位高于家用音響，其主要原因是由于汽車音響的使用環(huán)境要比家用音響的使用環(huán)境惡劣得多。網(wǎng)絡(luò)或電話溝通，就給你搭配方案（尤其是信誓旦旦自稱很的），絕大多數(shù)是純商業(yè)行為，只是賣汽車音響而按你的要求改音響
The main reason why the maintenance price of BMW car audio is higher than that of home audio is that the use environment of car audio is much worse than that of home audio. Network or telephone communication, to give you the collocation scheme (especially vow very much), the vast majority is pure commercial behavior, just sell car audio and change audio according to your requirements
在檢查電路時(shí)，通常需求辨明元器件是左聲道仍是右聲道，將攪擾加至這些元器件，通過改動(dòng)平衡旋鈕來改換揚(yáng)聲器發(fā)聲就能夠區(qū)分左聲道仍是右聲道的元器件不好。
When checking the circuit, it is usually necessary to identify whether the components are left or right channel. By adding disturbance to these components and changing the balance knob to change the speaker sound, we can distinguish whether the components with left or right channel are not good.
某一聲道高音無聲
A certain channel is silent
故障排除：先檢查分音器的配線是否接通，然后用電表從分音器端去測(cè)量有沒有聲音，可能是錯(cuò)將喇叭線輸入端接至低音輸出端。
Troubleshooting: first check whether the distributor wiring is connected, and then use a meter to measure whether there is sound from the distributor end, which may be wrong to connect the horn wire input end to the bass output end.
自己改裝的話記得所有電源線無論正負(fù)極都要加保險(xiǎn)絲、外套護(hù)管，所有過車架鐵皮切口的地方套橡皮圈（非常重要，為你的車不自燃）。
If you refit yourself, remember that all power cords, both positive and negative, should be equipped with fuses and protective tubes, and all the places that pass through the iron incision of the frame should be equipped with rubber rings (very important, for your car not to ignite).
