I have for sale an old school Rockford Fosgate monoblock amplifier model 351M. It is rated at 350 watts RMS at 2 ohms and that rating is without a doubt wrong! The birth sheets on these amplifiers were always 25%, or more, actual power than the manual listed. It is a subwoofer bass only amp and does not have the end caps. It is in decent physical condition for it’s age showing some signs of use and wear but perfect working order. I’ve included some additional specifications and features below.

350 watts RMS x 1 at 2 ohms

requires 8-gauge power and ground leads — wiring and hardware not included with amplifier

selectable 50-250 Hz variable low-pass crossover, 24 dB per octave

TRANS•ana circuit designs keep voltages low and signal paths simple in the pre-amp section, for minimum distortion and maximum musicality

MEHSA provides more efficient transfer of heat from MOSFET output devices to the heatsink for cooler operation

TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise

NOMAD — advanced protection circuitry for "intelligent" shutdown protection

preamp-level inputs

preamp outputs (for passing signal to another amplifier)

wired remote Punch Bass boost (0-18 dB at 45 Hz)
