The Punch 400x4 (pronounced “x4” not “by 4”) is a 4-channel amplifier which can deliver 400 watts RMS. This amplifier utilizes a 2/4-channel input switch to eliminate the need for signal splitters. Four internal XCard crossovers allow the ampli- fier to be configured for use with many popular system designs without the added cost of external processors. The Punch 400x4 is a powerful 4-channel amplifier with integrated features which are offered at a competitive price.

We strongly recommend you have your Authorized Rockford Fosgate Dealer install your new Punch amplifier. If you do choose to install it yourself, please be sure to read the entire manual before beginning.
