Hi> I just did an upgrade to my 07 > !
1.The top covers are held on by metal clips (CAREFULLY ) pull up slightly on the plastic till you see the clip then use long handled flat screwdriver to (carefully) pry the clip loose from the lower portion. These will break off easily from the plastic!!!!
2. You can now see into the area that holds the speakers and where the other clips hold the the panel on. (CAREFULLY ) pry those loose > do not pry too hard, the panel clips go through the speaker bracket and then to the metal of the car.
3. there are several small clips along the front edge of the panel that need loosened ( be careful they don't fall off and go into the lower panel abyss!)
4 the panel will slowly come off except for one push plug along the back edge of the panel wiggle it loose and your there.
I installed a pair of 5" diamond audios with tweeters > made an 1/4 inch MDF panel exactly the same size as the 5x8's and mounted the crossovers in the trunk
Just be sure nothing interferes with your top hydro cylinders they move up and down slightly when the top moves
If you have any other questions please let me know ( sorry this is so late just got on the forum>
