A capacitor is a bit similar to your car battery; it stores electrical energy. But unlike a battery it doesn't produce its own power, it simply stores it. A car audio capacitor will help you get the most from your amplifier. It will store power for release on demand, delivering it to your amplifier just when it's needed.
Your car amplifier requires a lot of power to play loud music, especially when there's lots of heavy bass. Without a capacitor your amplifier will be robbed of power by parts like your lights, engine, and air conditioner.
So what happens when your car audio amplifier doesn't receive enough power?
A common occurrence is dimming lights. In such a situation the light will follow the beat of the music. The light will dim each time a heavy bass note sounds. If you were to turn off the lights, your car stereo system would suddenly sound louder and the music would be cleaner.
Your amplifier is simply trying to use more energy than the electrical system can supply. If a capacitor had been present there would have been enough energy to power your amp. That electrical energy would have already been stored.
When you want to reduce headlight dimming, improve bass response, and increase the power of your amp, a stiffening capacitor is a must. Equipped with capacitor and an adequate power supply, your system will get every bit of current it needs. Voltage drops will be a thing of the past.
