AMP Ground - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I have replaced my factory AMP with a new one. When I originally hooked it up I had the ground wire connected directly to the battery. Someone told me that was not good so we moved the connection to the same bolt that the battery terminal connects to the body with.

The thing is now I get a lot of noise (sounds like an electrical motor running) when the radio is on. I am sure that this is due to a bad ground as when I had it connected directly to the battery terminal I had no such noise. The noise is coming from the speakers and goes away when I turn the car off.

The sound system also sounds a lot better with the car off and just the radio on.

So my question is this, is it really that bad to hook the ground directly to the terminal on the battery? Should I move the Ground back? Where is a good spot to ground the AMP?

BTW I am using 4 AWG wire for power and ground.

Thanks in advance.

Put it back on the battery , long as you have a fuse on the positive. you be find. less noise. thru radio.

Battery, seat belt bolt, main ground point (near battery) are all sufficient points for grounds.

Ground it back to the battery. If that does not clear up the noise, get a ground loop isolator for your RCA's.
