You're correct chrisp847. The 6x9s in the rear are actually two seperate speakers. There is the woofer part which is the actual 6x9 and then on top of the bracket over that one is the small, maybe 2", mid-range speaker. They are wired seperately as well. The Monsoon amp runs base to the woofer and then the mid-range sound to the smaller speaker.

Kind of symantics i suppose. I would count that as one speaker, but since they wire them seperately, I guess they are technically 2. You almost wonder if GM/Delco did that on purpose just so they could say "9 speakers" instead of "7 speakers". That's probably a bit cynical, though.
