Randall, Thanks for the PM. I was thinking about using the center channel for the reverse brake switch and rear camera video feed, but hadn't considered it for the speakers. I have enough of the carpet around the door sill up that I can run the rear speaker cables. There is actually a bit of space tucked in there and I found another wire bundle there already.

The carpet side piece piece is held on with two screws and some clips that fit in to the body. It popped right up. If I could get the passenger side kick panel out I could just roll up the carpet and put the cabled under the carpet. But so far, no joy.
