ROCKFORD FOSGATE ACCESSORIES

Energy Storage Capacitors

Energy storage capacitors are used to provide extra current needed by amplifiers to reproduce musical transients. The capacitors also have the natural ability to filter AC ripple caused by the alternator, reducing the chance of noise in the system. The Punch Caps are available in a variety of values and will maximize both the sound quality and performance that Rockford Fosgate amplifiers can deliver.
