Default Best place for an amp ground wire...
I need to redo my ground setup because when I added in my second amp I'm getting a squealing noise. I currently have them grounded to where the spare tire is suppose to screwed down to. I do have the paint scrapped off from there as well. Is there any easy way to run it down to the frame?

but that assembly the spare mounts is welded. I usually ground amps under the rear seat. be sure all the wires are the same gauge as well.

That maybe it. My both of my amps grounds are the same but I have a aux plug in the back too and that is just a small ground. Do you think that could do it? I redid my ground and I will post pic of it later because its still doing it. Then you guys and tell me what I'm doing wrong.

no, a cigarette lighter. I had a power inverter for my tv in the back but I took it back out for now. But I left the plug back there

power inverters introduce noise. I have that issue with a i-pod aux adaptor I use.

well it started when I put the new amp in. I had the inverter before the amp and there was no problem.

noise can be pinched RCA, bad internal ground in the amp, outside electronics such as aux adaptors and such.
