I've been having the same problem since I installed my aftermarket radio, got all the right harnesses. It's a steady constant whine gets louder when accelerating but not when you turn up the volume. Other than the whine at low volume it sounds excellent. I've read the whole forum, im going to try cleaning the 32 pin in the console but have no rear controls at all. 03 Silverado. Any other help would be greatly appreciated thanks

 

The bare wires are probably ground wires used to keep the noise level down on the cables. They should be connected to ground on one end only to avoid ground loops.

 

I have had a noise issue with my 2003 duramax 2500HD crew cab ever since I owned it. The noise issue for me is not a whine it is all the speakers start to crackle and pop as I increase speed. It starts at about 55mph and Anything past 65mph is almost unbearable for any length of time.
​​​​ I will confirm the rear stereo control is the problem! I removed it and problem disappears. After plugging in and out repeatedly the problem goes away.
This problem has been driving me crazy for years. I have disconnected and removed/replaced just about everything in my truck over the years and nothing until today has even remotely effected the noise.
I now have 394,000 miles on my truck and cannot be happier. So very thankful.

Best regards to all those who posted.

 

Hey people,

I'm from Germany and bought a 2007 Suburban. I have the problem that the speakers start to buzz or scratch when I turn on the RSE at the back. Unfortunately, no sound comes from the speakers either. I installed an aftermarket radio with a PAC RP5-GM31 Canbus adapter. Maybe someone has an idea to solve this problem?
