I recently bought a 2003 tiburon gt. I'm trying to wire up my amp and sub to my aftermarket cd player. I used a wiring harness and conencted everything just fine but the only thing that turns on is my aftermarket amp and sub, when my factory speakers and sub should be working but their not. I checked and everything was wired up just fine, I'm not sure if its my wiring harness or not but If I could hook my amp and sub up to my factory infinity stereo that would be fine for now, but If anyone could give me some ideas of what I'm doing wrong with it, I'd appreciate it.
I even tried connecting all 3 remote wires together, my factory + aftermarket both to the remote wire on the harness, and still nothing.
