Power capacitors or stiffening capacitors are used to assist a car that has a problem with dimming lights (voltage sag) or to help tighten up the bass. These capacitors store a large amount of power and then release it very quickly when the demand is the greatest from the amplifier. These capacitors release the current much faster than a battery can and do not force the amplifier’s power supply to be at a loss (due to a voltage drop) when bass notes and other transients are greatest. Capacitors should be chosen in the ratio of one Farad per thousand watts max or 500wrms.
