This 5 channel amp is powerful, but not as powerful as Power Acustik claims. To start it only uses 1 of the 2 100amp fuses that are plugged into it. After I opened it I noticed 1 of the fuses is just soldered to the board, it does nothing. Still the guts look like it does around 1,000 watts rms. I have it running my whole system and it puts out some power, and the music coming through my speakers sounds great.
