does anybody know how to take the the middle part of the rear seats off??
its the piece that has like a bag attached to it. I took the front part off they just snaped off but I dont know if its possible to take the rest off
thanks

 

On the B3 Audi 80/90 series they are just held in with some kind of sealant that easily separates. Not sure if its the same in your case though. Have you taken off the entire rear back to seat btw, you will need to to remove the ski bag. It should just pull up directly and pop off.

 

I've got a 1990 100Q. It's a ski bag btw. When I installed a subwoofer a couple years ago, I think the thing just popped off with a flathead screwdriver and a little force. If that's what you're trying to remove.
