濟南汽車音響升級http://www.szanyuda.com/介紹用絕緣膠帶或熱縮管將音頻信號線接頭處纏緊以保證絕緣，當接頭處和車體相接觸時，可產生噪聲。

濟南汽車音響升級建議保持音頻信號線盡可能短。音頻信號線越長，越容易受到車內各種不同頻率信號的干擾。如果不能縮短音頻信號線的長度，超長的部分要折疊起來，而不是卷起。音頻信號線的布線要離開行車電腦模塊電路和功放的電源線至少20cm。如果布線太近，音頻信號線會拾取到頻率干擾的噪聲。最好將音頻信號線和電源線分開布在駕駛座和副駕駛座兩側。
Ji'nan car audio upgrade recommendations to keep the audio signal lines as short as possible. The audio signal line is longer, more easily to be disturbed by vehicle in different frequency signal. If you can not shorten the audio signal line length, long part to be folded, not rolled up. Power line wiring audio signal line to leave the driving computer module circuit and power amplifier for at least 20cm. If the wiring is too near, noise from the audio signal line may gather frequency interference. The best of the audio signal line and a power line that separates the cloth in the driver's seat and the copilot seat on both sides.
　　
濟南汽車音響升級http://www.szanyuda.com/提醒當靠近電源線、微型計算機電路布線時，音頻信號線必須離開它們20cm以上，如果音頻信號線和電源線需要互相交叉時，我們建議最好以90°相交。
