This is my lil bros amp. It is a 3 channel is about all I know. I think the sub out does 250X1 @ 1ohm and the 2 channel does 100 watts. I saw somewhere that said 350 instead of the 250 so I am not sure what it does. I do know it WORKS. $50 shipped.....open to offers. Also have it listed with 2 power hx2 15's in a WTT ad.
