B5 factory stereo wiring - what goes to rear amp?
 

My 1998 A4 has the standard concert tape deck with the factory rear amp and speakers.

Which of the coloured wiring blocks that go into the rear of the radio contain the wiring that carries the low voltage signal to the amp?

This article should tell you about the wiring diagrams and such. it should be the same for b5 a4's... good luck :p
