Okay story is my g.f had her system on her stock deck, remote into a split, rcas into that small box with three wires, we bought a brand new jvc deck from walmart, and a subie clip, got the deck installed, i moved the remote to a remote off the cd player, everything worked fine untill we moved the cd player. We blew a fuse on the fuse panel, which I replaced which fixed the cd player issue, but now the amp won't turn on. She has a pioneer 12" sub with a sony xplode amp.
I found out when I unground the cd player, the amp turns on, when you ground it back up, the amp turns off.
I have heard the ground from the amp is grounding somewhere else and interfering.
