So I found out I have a BOSE system?
 

When I first got my 1995 Camaro it needed a cd player. When I started wiring the cd player in I noticed it had different wires ran than stock. The previous owner had put their own wiring in to each speaker. Today I went to change the front door speakers and found out I had BOSe sound. Well I have a few problems:
1) Can I hook this up to an aftermarket stereo and how would I do that?
2) Which wires would go from the BOSE box to the speaker?
3) Is it really worth it to hook it up?
