Here's the predicament...

I have a 2002 S2k. I wanted better sound from my music so I added a headunit and door speakers. everything is fine there. I wasn't happy with the sound so I added an 8 inch sub, which filled in the music perfectly. I'm driving down the highway about a week ago and for no reason the sub just stops. I figured I blew a fuse so I continued driving and when I had time to stop and check, the fuse was fine. The radio never quit working and everything else was normal. The amp still had power, and there was NO SOUND at all from the sub which implied it wasn't blown. when I got home my first thought was check the RCA's, so I switched those out and still nothing. then I thought maybe my amp was bad since it had a few years on it so I bought a new amp...and nothing. I switched in a different, known good sub...and nothing. I borrowed a friends known good headunit...and nothing. In all of this I noticed, that for some very strange reason, when I would disconnect the RCA cable the amp would turn off, and would come back on when they were reconnected. Why would this happen? I've traced back every wire I ran, nothing is grounding out anywhere. The sub worked before and now has stopped receiving sound altogether.

I tried to figure out if some other fuse was blown so I grabbed my fuse tester, and no fuses displayed power with the car off or on. I switched to a normal "ice pick style" 12v tester, and still no fuses display power. My car runs perfectly fine, no burnt wires anywhere, everything works..but no power to ANY fuses? please tell me someone else knows what's going on.

answer here or you can PM me you phone # as I'm trying to get this resolved today. Thank you!

well I found the problem, I switched out the connector on the ground to the amp and it fixed all of the above listed problems. I suppose this can be a reference for anyone else who ever goes through this issue.
