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 capacitors are available in a variety of values and will maximize both the sound quality and
performance that Rockford Fosgate amplifiers can deliver.
®
ATTENTION: We recommend your Authorized Rockford Fosgate Dealer install your new accessory.
• Recommended capacitance is 1 farad per 1000 watts
