My first post...
I have a Audi 00 A4 with a Bose Radio system.
The Problem started with the Driver side door speaker going on and off with every bump or turn (now it stays off more often then on). I thought it might be a loose wire in the door but now the Passenger side door is doing the same thing. A lot of static when it's on.I now have times when just the back speakers are on.
Now I'm not sure if it's the Radio or the wire to the speakers now.

Thank you for any help

Get a good look at the wires, they might be loose or have lost connection to the speakers. Chances are, that's the problem.
