Great Amp and Performance

I actually found this amp online used for a budget build and only paid $50. Well I can't be any happier because this amp is solid. I have used it in 3 channel mode powering 2 front speakers off front channels and one 10" Punch P2 @ 4ohm from the rear channels bridged. I recently moved my rear deck speakers to the floor of my front seat and have them bridged at 2 ohms!! It never has cut out and I always have my music as loud as my head unit will allow and the quality of the sound, in my opinion, doesn't drop one bit. Of course, it's not recommended but if you know RF then you know they are made to do more than you expect. This amp has been discontinued for a while but if you find this amp used and pretty cheap, hop on the deal.
