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.

ized requirements. You can get the following XCards from your
