When I bought my A4 I noticed that the rear speakers sounded **** (in fact maybe only one of them was even working at all), so I had a little look at them and found a chunk of metal with a couple of BARE wires coming out of it and it had a little blue connector plugged into it. I have since learned that this is supposed to be an amp!? I found this picture of it that someone posted in another thread... (What a beast!!) What I'd like to know is what the green and black wires are supposed to be connected to? Hopefully once soldered to something, this will fix my dodgy speakers. Also, on the pasenger side in the boot where the tool kit is stored, what is supposed to be in the space under the tool kit? Cause whatever is supposed to be there; isn't =[ Can any one help? Thanks.
