Front door:
1. Remove the door trim panel. To do this, you will need to remove the screws that hold the panel in place. There are two screws located at the top of the panel and two screws located at the bottom. There are also two screws located on the side of the panel near the window. Once you have removed all six screws, carefully pry the panel off the door.
2. Remove the old speaker. Once you have removed the door trim panel, you will be able to see the speaker. The speaker is held in place by four screws. Remove these screws and carefully pull the speaker out of the door.
3. Install the new speaker. Place the new speaker in the door and secure it with the four screws that you removed in the previous step. Make sure that the speaker is properly seated in the door before you tighten the screws.
4. Replace the door trim panel. Carefully align the door trim panel with the door and snap it into place. Make sure that all of the screws are properly tightened.
