The Rockford Fosgate Punch series of amplifiers delivers Rockford Fosgate's technologies at a price point that make similar comparable amplifier brands seem expensive. The Rockford Fosgate Punch amplifiers are 2 ohm capable and feature on board Punch Bass control. All Rockford Fosgate amplifiers are CEA 2006 compliant meaning the rated power of the amplifier is certified true and accurate,many other amplifiers quote extreme peak power output but when tested, if they dare, never live up to their ratings. Rockford Fosgate Punch amplifiers deliver true reliable power to your speakers and subwoofers.

This amplifier is a 4-channel amplifier rated at 400 watts RMS (total) designed for running front and rear channels. The P400X4 Rockford Fosgate amplifier also utilises Class A/B technology delivering higher efficiencies whilst maintaining a smaller foot print.

Rockford Fosgate - The Company

In 1973, in a garage, Jim Fosgate created his first car amplifier and the Rockford Fosgate brand was born. Since then Rockford Fosgate has been at the forefront of the car audio industry creating some of the loudest and toughest car speakers and car amplifiers money can buy without sacrificing sound or build quality.
