Rear deck to access Woofer W203
If not, maybe if you remove the seats:
Pull the seat cushion out from the rear. Push your hands down between the cushion and the seat back, get a grip and pull it up and out.
The seat back is held on by brackets at the bottom that will now be visable; push down on the seat back to disengage the brackets.
Hope this helps...
I'd stop by a body shop and see if they will give you a little free advice.
Maybe take them a six pack...
