Rockford Fosgate T4000.1BD , 4000 RMS at 1 ohm. Everyone knows birth sheets of these amps usually say 4300-4800 RMS watts @ 1 Ohm. Had this amp running (4) 15’s for the time I had it installed. See picture for power rating numbers, straight from Rockford Fosgate. Moving out of the country so we are trying to downsize the car stereo collection we have in storage.
