The tweeter box is attached to the door panel so the whole door panel will need to be removed. Remove and unplug the switch panel on the door panel. There are two torx bits under the handle on the door panel (little plastic caps should be covering them). The rest of the panel is held on by plastic clips, a clip removal tool is ideal although a long flathead screwdriver will work. Pry up a corner and remove the rest of the panel by pulling easily all the way around it. Don't forget to unplug the courtesy light and the tweeter speaker wires before completely removing the panel.
IIRC, the mirrior is attached by 3 nuts and I believe theres a wiring harness to unplug. Never went this far. Just removed the power window motor and regulaters on both cars over the years...
