济南汽车音响改装http://www.sdcarmusic.com/介绍功放的电源要使用“大水塘”滤波电容，因为大容量的电容电感量大，所以要并联小容量的电容以“提高电源的速度”。

1、济南汽车音响改装介绍把整流后得到的脉冲直流电进行滤波以减小交流干优，高速供电。
Jinan car audio conversion was introduced to the rectified DC pulse filtering to reduce exchange dry superior, high-speed power.

2、济南汽车音响改装http://www.sdcarmusic.com/介绍电容器能为音频信号提供通路。电容的对电源的滤波作用，对于功放只是表现出是否有交流干扰；电容的贮能作用可以为功放的瞬态大电流需要提供电能，但变压器功率不足不能为它及时充电，它的贮能作用就不明显了；而它为音频信号提供通路对音质和音色的影响也是至关重要的。
Jinan introduced capacitor car audio conversion can provide access to the audio signal. Filter capacitor on the role of power for the amplifier just to show whether there is hum; the role of energy storage capacitors for high-current amplifier transient need to provide electricity, but the transformer power shortage can not charge for it in a timely manner, its role in energy storage is not obvious; and it provides access to the quality and impact of audio signal tone is crucial.
