How do you replace speakers in a Pontiac vibe?

To replace the speakers in a Pontiac Vibe, first, remove the door panel by unscrewing any visible screws and gently prying it off with a trim tool. Disconnect the speaker wiring harness and unscrew the old speaker from its mount. Install the new speaker by securing it in place, reconnecting the wiring, and then reattach the door panel. Finally, test the new speakers to ensure they are working properly before finishing up.
