I just read many reviews on this amp. Almost every one says that the weaknesses is it over heats more then enough. Make sure it is very well vented. Oh and is the "Protection" LED comming on when the amp cuts off? I think that it is just overheating

. The two-channel design is rated at 80 watts per channel into four-ohm speaker loads, power output doubling when impedance is halved. Use it in bridged mode and you get 320 watts on tap. What gauge wiring are you using also???
