I am selling a Rockford Fosgate Punch Amp. My boyfriend had it installed in my previous vehicle and I no longer need it. I don't know much about it but I have researched a little and it is going for starting bid on Ebay at 400.00$. The guy on ebay had these specs listed for it. If that helps?. It is in good condition and was rarely used (not so sad to see I don't have it honestly). Rated at:. 200 watts RMS x 2 @ 4 Ohms. 400 watts RMS x 2 @ 2 Ohms. 800 watts RMS x 1 @ 4 Ohms Bridged. 2400 watts Max Power. If you would like to see it please call.
