The following accessories were designed to enhance the perfor- mance of the Punch 4020 amplifier.

Energy Storage Capacitor (PCH-C1)

The Punch 1 farad capacitor is used to provide extra current needed by amplifiers to reproduce musical transients. The Punch Cap also has the natural ability to filter DC ripple caused by the alternator which can result in noise in the system. The PCH-C1 will maximize both the sound quality and performance that Rockford Fosgate amplifiers can deliver.

Punch Link (FG-LINK)

The Punch Link is a specially cast heatsink interconnect which allows you to join any of our current Punch or Punch Power amplifiers together. While providing additional cooling through the coupling process, the Punch Link adds the finishing touch by giving you the look of one awesome amplifier.
