Hello, today I was bumping a friends jl 12w3 v2 in my s10 off my my infinity 7540a. The amp is a 4 channel and I had the rear 2 channels bridged pushing the sub at 4 ohm recieving about 200 watts in a 1.3cubic foot sealed enclosure. Anyway the amp was working fine and I took the sub out, who knows why??? and when I went to put it back in I noticed the power light had went out on the amp. I checked all the wires and I couldnt get it to go back on. eventually I took the remote wire out and started to push it in and out of the amp, the protect light would flash on every know and then. Eventually after messing with it for a long time I got the power light back on but it would keep going out and then back to the protect light? Could you anyone help me figure out whats wrong with my amp? thank you
