1. Wedge a flat head screwdriver under the edge of the speaker grill.
2. Pry up on the grill. There are several retaining clips holding the grill in place. You may end up breaking these clips off to remove the grill. It's okay to do so because you will be replacing these covers with new ones.
3.Work the screwdriver all the way around the edge of the speaker cover. If you can get your fingers underneath the cover, it may make it easier to pry the cover up. Once the cover is removed, clear the mounting brakes of any broken retainer clip pieces.
