Alrighty,
After you take out the two screws, you're going to pull off a bunch of these little white clips around the door. You can see one that stayed in the door instead of on the panel on the left side about half way down. Don't know why that one didn't come off on the panel like the rest of them. There is a panel remover tool for this you can buy. I used a screwdriver for leverage.
Unplug the wires that connect the mirror motor. It was an easy push one thing while you pull another kind of deal.
The last part is the little metal bar that is attached to the door handle (not the window switch). I can't find a picture of it. The end by the handle ends in an "L" shape that you push out of the hole it's set in. Then the bar is only attached to a little plastic piece. You just pop/twist the bar off the plastic and you're ready to go for it with the speakers. I really wish I could find the picture of the bar, it'd make a lot more sense (you can kind of see it with some sort of blue wrap on it in front of the black bundle of wires in the first picture.
For me the funkiest part was lifting the panel over the door lock.
Hope it helped, good luck!
