Ok, so I just went ahead and gave it a go. The process is a bit of a pain, but its doable. Your main goal is going to be to remove the two interior panels that are back there to expose the subwoofer. These two panels being the one covering the subwoofer and the panel above it. The top panel must be removed first because it overlaps the bottom one. For the most part the top panel just pops out, there are clips along the edges that need to be released. Also there are screws in the middle where what I believe is the cover for the back is inserted. The bottom panel is a bit more tedious to remove. First the rear seat has to be removed. If the carpet is peeled back you will see several screws that need to be removed. Two screws will have to be removed from a carpeted piece of platic that runs the width of the vehicle in order to fold it back. This piece is part of the open area that houses the third seat. Also, near the rear door there are two more screws that are hidden. There is a hook/latch that will need to be removed in the corner in order to release a small patch of carpeted plastic that covers one screw. You're going to need a socket set for this. Also, the plastic cover that runs along the rear door will have to be removed because its leftmost section covers a screw. This should pop off after you realease all of the clips. The top panel that was removed in the beginning was covering several screws on the top of this panel that needed to be removed also. After that you should be able to remove the panel. You will now see that the subwoofer is bolted and glued into the vehicle. Remove the bolts and you might have to pry the sub off with a little bit of force because of the glue. You should be good to go after that. Hope this helps for anybody that might be looking.
