Hello all,
Just got a A3 came with a alpine HU and only the front speakers worked, I replaced it with my Sony HU and same problem. After looking I needed a harness I have tried PC9-401 and 410. It is half amped tried both no good. But the original Audi HU in and still no rear speakers. What can I check to see what the problem is? Do you think the AMP in dead for the rears? Really confused. Thanks in advance
