BOSS Audio Systems CAP8 Car Capacitor - 8 Farad, Energy Storage, Enhanced Bass From Stereo, Warning Reverse Polarity Tone, Voltage Overload Low Battery Voltage Led
A capacitor is a passive (it consumes, but does not produce, energy) two-terminal electrical component. In building a sound system for your car, you would want to use a capacitor for a couple of different reasons.
The main reason a capacitor is always recommended is for power reserve. The capacitor stores energy and releases it very quickly to the amplifier(s).
Music is dynamic, no matter what type you listen to, and the dynamics can vary quickly, going from soft voices to thundering bass notes. These moments are where the benefit of having a capacitor is heard. The amplifier requires a constant amount of steady power to function efficiently and power the speakers. A capacitor will keep the power going to the amplifier consistent and stabilized, which means a better-sounding system.
Important: The remote output of the head unit is connected to the remote turn on of the capacitor. The capacitor will not function if the remote wire is not connected to your head unit.
