Door speakers are absolutely aftermarket.

I had to go back out in the cold to check. I was fooled by the Bose plate in front of it, not ON the speaker. So when I replace it, get a GM radio that is not a Gold Bose system?

[Eric DeVirgilis CLC# 8621]

Correct.

May have to some detective work on how they have the system (re)wired.

Barney, I suggest that you investigate what sort of butchery was done to the speaker pods themselves. If the Bose hardware is still inside and they didn't totally wreck the pod screwing the speaker in, the amps can be rebuilt fairly inexpensively from a service or really inexpensively if you know what you're doing with capacitors and a soldering iron (I, for one, do not). The Bose speakers themselves are still good, they last forever. Properly working, it is a really great system, definitely worth salvaging if it all feasible.
