Did this last weekend to replace the stock speakers.
1.) Pull off the upper (2) plastic trim panels on each side of the window. These are held in place by clips only and require a decent, but even pull.
2.) Pop the window switch trim off the arm rest, disconnect from wiring harness.
3.) Within the arm rest where you remove the switch panel, you will see a black bracket with (3) bolts. You only need to remove the (1) larger bolt going into the door panel. The (2) that attach the bracket to the arm rest can be left in place.
4.) Pop the narrow cover plate off of the door handle bracket. You will see (2) screws inside, remove them both and pull the handle off.
5.) Now you should see (3) bolts left holding the door panel on. (2) on top that were behind the plastic trim you popped off, and (1) exposed on the bottom under the storage compartment. Remove all (3) of these.
6.) Now just grab the door panel by the arm rest, lift up and pull back. If you've taken off all the right parts, it comes off very easy.
7.) Now you have access to the speaker. Assembly is just the reverse.
I also took some pictures... if I can figure out how to upload them I will. Sorry, I'm new to the forum...
