No Sound on Drive side front and back


Registered User
Hi All

So I have recently had to get an amp off ebay for my Audi A5 which has a B&O system.

My AMP had died.

I have now fitted my AMP from Ebay and have sound, However the sound I have is only on all of the passenger side. I do not have any on the drivers side front or back.

I have been advised it could be the T Harness, Which I am getting checked this week.

Any other ideas? Or any ways I can check without spending a fortune.

According to your profile page you have a B8, is this correct? If so then this is for the B9...
