I just got an awesome deal on a great condition US Amps AX5600. Seeing that it's going to be for a future build, I won't be getting more stuff for a while. I do know that this amp is pretty underrated, 1/0 gauge wire terminals speak for themselves as well. Does anyone have any experience with its actual ratings? I read somewhere that it's much closer to 100x4 at 4 ohms and 700x1 at 1 ohm.
