How do I remove rear and door speakers in a 2000-2005 Buick Lesabre? Any help is appreciated!|||Remove the door panel. Some Lesabre's in that period had speakers screwed in, while some had them riveted in to the door. If screwed in, unscrew. If riveted in, drill out the rivets, making sure to use the smallest drill bit that will still get the job done. This is to be sure you can reuse the screw holes if you're installing new speakers in the same location.
