fold down your back seats and pick up the carpet at the very bottom of the seat backing. You will see a bolt on each side of each seat (either 10mm or 12mm). Take these four bolts out and the seat backs will come right out. Now as for the bottom part of the seat, i'm pretty sure they are just clipped in...just yank them out. It's not too hard, you have to take them out to replace the rear speakers.
