Hi I tried to fit in my new aftermarket radio using this wire but I still have no speaker/subwoofer sound from the back. I have a 2005 a3 8p 5door 1.6FSI with half amplified rear speakers.
I believe it is not bose as it does not say it on the doors.
How is the cable meant to be wired into the stereo. Any diagrams or how to's?
Any help would be appreciated
After market stereo: Alpine CDA-137BTi
