Two things .. I'm looking for a rear Bose speaker wiring diagram and a fix for my speedometer.. it is not moving at all. I have watched some YouTube stuff but nothing so far works. Everything else on the cluster works. Junkyards are hell to get to. Just not enough time last one I went to the car was behind and under 10 cars.

 

There are places that will repair speedometers. Have you considered that? You can get used parts on line, such as carparts.com. Have you tried ebay? Search for instrument cluster.

Here is a link the service manual (known as FSM) section with the wiring diagram. The diagram starts on page 166 and runs for several pages. The rear speakers are on page 171. A block diagram is page 164 which will give you the big picture.

If your sub is cutting out or all the way out there may be an easy fix. It's a common problem. Check out the links below.
