ok here's the deal i pulled my box out to glass it and paint it it was out for about 2 weeks i put it back in and the amp doesn't work now i've seen enough blown amp and that doesn't seem to be the problem all lights are on no protection lights on it clicks like it's kickin on but nothing i switched the rca to see if that was it but nothing usually when a power supply goes bad you get a protection light so this one has me puzzled BTW it worked fine when i pulled the subs out and i didn't pull the amp out so no wireing has changed sorry for the novel
