First thing - Are you replacing the Bose system? If so you will need some sort of adapter since the Bose speakers attach to the panel with a 3 point triangular system.
A good post on that is here:
Ok - this is from memory:
There are 3 screws you need to remove along the edge of the door. I think two in the rear and one up front. You also need to pull out the plastic piece under the door handle/pull. 2 screws will be hidden beneath it that need removal. Best way to pull out the plastic is to put your fingers on the inside part and push in and down. It should come loose, and wiggle out from there.
Once the screws are out you need to pull up on the door panel and it should slide out of its clips.
Now before you pull the door panel completely away you need to disconnect the door handle lever from the cable. Peel away the liner behind the panel so you can get access and unhook it. Also you need to disconnect all the plugs for the windows and electrical. Mid the color co-ordination of where they are plugged in. Makes it easier plugging them back in so that your front switch doesn't end up controlling your back window!
Here's a pic of the door (I have pics for everything...
) The thick white cable running diagonally is the latch cable you need to disconnect at the door lever.
