How do you take rear speakers out of 2007 Buick lucerne?

To remove the rear speakers from a 2007 Buick Lucerne, start by carefully prying off the speaker cover using a flat tool to avoid damage. Once the cover is off, unscrew the mounting screws holding the speaker in place. Disconnect the wiring harness connected to the speaker and then gently pull the speaker out of the enclosure. Reverse the process to install new speakers.
