For sale is this Rockford Fosgate P400-4 amp. It's rated at 50 watts x 4 into 4 ohms, 100 watts x 4 into 2 ohms, 200 watts x 2 in bridged mode into 4 ohms.
I was using it in bridged mode to drive a set of Boston Acoustics Pro 6.5's that had large external crossovers and it always performed well.

This is a pretty versatile amp with multiple wiring options and crossover points, gain adjustments and a port for a wired remote. (Remote not included).

Comes with the user manual. There are no significant scratches or marks, all the connectors, switches and dials are in very good condition. The unit was mounted in the glove box compartment so it never really got exposed to anything other than dust.

Does not come with any external wiring, fuses, etc. Just the amp.
