I tried fitting the Excelon in the bottom slot, but found that it's external tuner module, and cables got in the way. With no easy access to the back, it was impossible to move them around to get it to fit. I'll try sometime later this week (too much rain right now) and take off the sides of the center console to try to get better access back there. I'm still hunting a problem with my back right speaker (signal is fine, speaker wire to wiring harness is fine, just nothing past that..) which I suspect lies in the wiring harness adapter I made.
