Why use a power capacitor?
This power capacity is an energy storage device. It is designed to supplement you car’s charging system, when your audio amplifier places a high current demand upon it. This occurs, for example, when the music you are playing contains a loud, transient, deep bass signal.
The overall bass response of your system will be enhanced by using this device. Since automotive batteries are not designed to deliver the current required by modern car audio systems, a capacitor such as this one, which is capable of discharging extremely rapidly on demand, is a logical addition to your audio system.
In addition, this capacitor can filter out the AC voltage induced in the amplifier’s power supply. Unchecked, this voltage can cause audible noise in the sound system. It is recommended to use a capacitor with a minimum of one microfarad (1F) for each 500 watts of amplifier power. (you can never have too much capacitance for any audio system).
The 
capacitors feature a digital voltage display.
