First of all, how rare are these third row seat models? Any info on that option would be appreciated. Anyway, my car has an aftermarket cd player and nice, although small, door speakers. I would like to add a little bass to the system without comprosing the pop-up 3rd seat. I was thinking either mounting some 6x9's or possibly a bazooka tube in the hidden storage area. I'm not looking for an insane sound system, but would like to actually know there is a bass line in my music. Any of you with a nice sound system in your 3rd row seat equipped wagon, please let me know what you've done in order to continue utilizing quite possibly the coolest part of the car. Thanks a lot.
