OK, I know this may have been covered but I have not recieved a good theory on this.
I installed the AVIC-D3 into my Cadillac Escalade with Bose and ONStar.
I have a hissing noise from the speakers when no music is on. Now is this from my factory amp? Do I have a factory amp? How do I by pass it?
Or
What can I do to make this hissing noise stop?
Thanks!
