    You have to pull the rear seat and then the rear panel to get to the rear speakers.

    Most door panel removals can be done with a Phillips screwdriver and by simply pulling the door panel off by hand. Just look for screws at the edge of the door panel, near the door handle or inside the door pull. Once you remove all the screws, you should be able to pull the door panel off with ease. You can get to the rear speakers on most late model cars one of two ways. You can remove the rear speaker grills from some vehicles simply by removing screws that hold down the speaker grills to the rear deck lid. These screws are usually located on the bottom side of the rear deck (accessible through the trunk). The second way would require you to remove the deck lid from the interior of the car. On some cars removal of the rear seats is required to get to the rear deck lid. Hope this helps. Good luck.
