Possible GM24 Problem.
I made a GM 24 harness to add an amp to my system. Followed the instructions on the forum. I had just the rear hooked to a sub amp and all was good. I changed amps to a four way so I could have door speakers and a sub. My four way amp has F/R inputs. When I connected it all together, I got major engine noise and whine. I put GLI's inline both and took out a lot but not enough. They make a Pac Audio AOEM-GM24. Could my harness that I made be the problem and could the better made one be the answer? Anyone have a problem with a self made GM 24?

Thanks Markcz for all your help with my problem. That's the only component that it sort of " rigged". I'll change that and if there's still a problem, it might just be the amp. I'm getting good at removing the console.

I'm going to put my old 2 way back in and see what happens. That amp did not have any noise. How do you ground RCA cables? I know the outer ring is negative but how do you wire a ground to it?

If the outer contact is exposed you can solder or tape a wire to it. pic
Making a new adapter with a ground cable is another choice. pic
Some do stuff like this
Whatever is easy for you and makes it sound good
