济南汽车音响升级http://www.sdcarmusic.com/介绍用绝缘胶带或热缩管将音频信号线接头处缠紧以保证绝缘，当接头处和车体相接触时，可产生噪声。
Ji'nan car audio upgrade introduced with insulating tape or heat shrinkable tube audio signal wire joint wrapped tightly in order to ensure insulation, when the office and body joint contact, can produce noise.

济南汽车音响升级建议保持音频信号线尽可能短。音频信号线越长，越容易受到车内各种不同频率信号的干扰。如果不能缩短音频信号线的长度，超长的部分要折叠起来，而不是卷起。音频信号线的布线要离开行车电脑模块电路和功放的电源线至少20cm。如果布线太近，音频信号线会拾取到频率干扰的噪声。最好将音频信号线和电源线分开布在驾驶座和副驾驶座两侧。
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.
