Rockford Fosgate P400-1

The Rockford Fosgate P400-1 is a mono amplifier designed for medium to high-powered subwoofers. Capable of outputting 400 Watts of power, the amp can augment an existing system with powerful bass backup.

Bass and Treble Punch EQ are available, and an optional remote allows them to be adjusted on the fly. A variable crossover is also used to enable precise tuning, and a 2-Ohm resistance allows for a more stable output that can be sent to up to four 4-Ohm DVC subwoofers. LED indicators on the top show Power, Thermal and Protect statuses, and the small size of the amp allows installation under a seat for easy access when needed.
