So i bought this car with an aftermarket HU allready installed, however the speakers in the rear doors do not work, which doesnt really bother me, but when i mounted a towbar i found out there is a subwoofer in the boot inside the panel on the drivers side, so i want that to work, so i removed the HU and this is what i found.


I need help with what color is for what, and there are two white unconnected wires?

bumping this since im pretty much in the same boat. thought i had the original player installed when i bought my A4 last week. Changed to an aftermarket sony player and only sound from the front speakers.

Guess ill have to do it the hard way and remove the doorpanel and panel in the boot and check what colour the wires are there.

You need a wiring diagram - I know that Bentley has them
