Just got a 1600W 2 channel amp. Power Acustik power series, used. When I first bench tested it, I got the red "protection" light, then it went away. So I installed it in the truck on 2 of my drivers, all wired in properly(been doin this awhile) It got the green power light and played fine... Moments later it quit playing, but was not hot and didn't blow a fuse. Also it was not being driven into clipping or even NEAR it.. I was still adjusting my crossover.. I think it is somewhere on the input side because if you play with the bass boost and crossover switches it clicks in the speaker just so slightly, like a functioning amp with no input. So, anyone heard of this and is there a surefire test?

the fix for mine was to disconnect the amp completely, open the case, and spray everything down heavily with CRC QD Electronic Cleaner, it costs about 5 bux at any autozone and is extremely handy. this fixed the issue, i then sprayed the connectors down with rid-ox and used an rca adapter as a cleaner (ie inserted it into each socket while wet and rotated it a few times), also installed a new set of rca cables just to be on the safe side.
in my case the amp was stored in a trunk and had something either spilled or condense in it, a good cleaning of the board took care of the problems and it has been working now for the past 4 months.
hope this helps,
trin
