Default 86-89 BOSE Head Unit and Speaker Rebuild Guide with AUX Input

All,

I spent a lot of time gathering information about rebuilding the 86-89 Bose stereo and speakers from the forums and across the Internet, including getting my hands on a set of factory schematics which allowed me to add an AUX input to the system. In order to preserve the information and help others, I compiled an extensive document on the procedures including:
  • Why the Capacitors fail
  • Replacing the speaker capacitors
  • Replacing every capacitor in the Head unit
  • Refurbishing and cleaning the cassette deck
  • Adding an AUX input to the radio
  • Parts lists for cassette belts and LED lighting for the head unit
The doc is attached as a PDF to this post and is 55 pages or so long. I tried to document each step with pictures to make it easier to follow along.

Have at it and feel free to PM me with suggestions or additional information you have that might be useful to include.

NOTE: Although I have the factory schematics, all of the diagrams within the document are original to me so there should be no copyright issues with this doc.
