We need more detail than just loud noise. Does the noise pitch increase with your rpms? Re-do your grounds and scrape off the paint before you screw into the metal.

not really, the sound does not increase with rpms but when i put into Drive, it makes some noise.

I'll try to scape off the paint and try it again.

Like, where exactly is the good spot for ground? solid metal?

did you run the rca's next to the power wire? if so it would cause that type of problem.

+1

did you run you power opposite of your RCA's?
you should, if you ran all you wires together you would get noise
alway run the power on the opposite of audio wires

Thank you.

I sanded the paints, separated the RCA cables away from the power wire.

not only the sound went away, there was this sound that came with rpms when a/c was on. That sound also went away.

Thanks
