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.

Any ideas?

I have heard the ground from the amp is grounding somewhere else and interfering.

Yeah you have some mixed grounds somewhere. I'm assuming you mean you have a CD changer in the trunk or something of that sorts?

With the way your setup is now, you should completely bypass the whole splice box thing for the amp. Run RCAs and the Remote wire directly from the Headunit. You'll get much cleaner sound that way as well, and it will ensure all your connections are proper.

Ohhhhh...you're doing it the 1990s way. The JVC is a trunk mounted CD player in the back? Why not just get a new head unit then?

In my defense, you're saying head unit, then CD player...separately. Making it sound like there are two separate units.

any way still the same problem the cd player/headunit in the dash still has grounding interference.

Yeah the only way to tell for sure is to pull it out of the dash and see what wires are going where (very easy to do btw). Its definitely a crossed ground issue.

I have tripple checked all the wires that I did, everything matched up, do you need the ground to the chassis in these cars?

Amp, yes. Head unit, yes (which should be grounded already as long as the wiring harness is correct).
