it is the same (if I know the one you're talking about)

first you pop up the rear seat from the clips,
then undo one bolt on each of the sides of the seats on the bottom and pull those columns up and out,
then you take off the side pillars(the interior trim piece) there's about 5-6 clips that hold that in place, be careful not to brake them as you take them out,
after that where the seats fold down, there are about 7 clips you take to take out to get the carpet loose from the vertical frame,
after you get those out and the side pillars are off you can pop up the deck (it's sitting on two clips) and bingo you got yourself the speakers (or rear strut tower nuts) whichever you were looking for back there
ps. forgot disconnect the break light after pushing the whole box to the left and then up to take it out so it doesnt get in the way or you don't pull out the wires heh
