2007 Tahoe LTZ - BOSE Radio.
I seem to be developing a whine in my rear speakers, I have replaced the rear center console heater control unit with 2 different new GM units and they both did the same thing. So I highly doubt that the rear controls are the issue. I am wondering what others have found. I suspect a ground, because sometimes when I hit a bump it gets louder, then another bump and it goes away. If I unplug the rear controls, the noise goes away, and obviously I do not have any sound from the rear speakers.
I have considered a few things to fix this:
1) Making a jumper to bypass the rear console unit altogether.
2) Buy some sort of noise filter
