近年来随着济南汽车音响 http://www.sdcarmusic.com/行业的发展，济南汽车音响电容的使用也日益普及，那么电容在音响系统里的是什么呢?
In recent years, with the development of Ji'nan automotive audio industry, the use of Ji'nan car audio capacitor is becoming more and more popular, then the capacitance in the sound system is what?

1.能够减小济南汽车音响机头及功放由于电源不良所带来的噪音。
1.To reduce the noise caused by the power supply side of Ji'nan car audio head and power amplifier.

2.在播放大动态的济南汽车音响节目源时，减小由于突然电压降而带来的功放非线性失真。
2.When playing the large dynamic Ji'nan car sound program source, the power amplifier nonlinear distortion caused by the sudden voltage drop is reduced.

3.在优良的济南汽车音响 http://www.sdcarmusic.com/系统中（对于低档的汽车音响系统作用是不明显的），由于电容的蓄能和瞬间充放电特性，可以使中音区部分表现饱满；高音部分声音通透性更好，声音更明亮；使其低音部分更充实浑厚。对汽车音响音质的提升具有不可替代的作用。
3.In excellent Jinan car audio system (for low-grade car audio system is not obvious), due to the capacitance of the storage and instantaneous charge and discharge characteristics, can enable Alto District, part of the full performance; part of the treble voice better permeability, sound brighter; the bass part of a more full and vigorous. The improvement of car stereo sound quality can not be replaced.
