The Punch 400x
4
(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 400x
4
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.
