The following accessories were designed to enhance the perfor- mance of the Punch 400x4 amplifiers.
Energy Storage Capacitor
The Punch capacitors are used to provide extra current needed by amplifiers to reproduce musical transients. The Punch Caps also have the natural ability to filter AC ripple caused by the alternator, reducing the chance of noise in the system. The Punch Caps 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.
