Capacitors are used in car audio systems that require additional power on an instantaneous basis. This occurs when heavy bass hits deep notes. During these bass notes, the current demand on the system is increased and can cause voltage drops. Capacitors act as a power reservoir, supplying added power to keep your system playing strong. If headlights are dimming while bass hits a capacitor will increase your bass and the amps exert the true power they are capable of.
