The following instructions are for replacing the factory 6.5" round door speakers in your 1999 Toyota Tacoma with aftermarket speakers.
- Remove all the items from the door frame. (image #2)
- The armrest has two screws.
- The door latch has one screw. After you remove the screw, the unit slides forward and then pops out. Then you have to remove the clip from the rod.
- The window crank has a clip behind it that holds it in place. instructions
- The door panel should pop off now. There are a few plastic clips that hold the panel on. These can be easily pulled apart. I didn't remove the panel from around the window section.

- There are five screws that hold the plastic speaker mount to the door frame.
- Unhook the plastic wire harness.
