I have a rattle on the passenger side rear speaker panel. I can press the top edge of the speaker grill while someone else is driving and the rattle is gone so I know exactly where it is. However I can't see how to remove that panel to gain access to the backside of the speaker grill. It appears the actual speaker grill is mounted to the backside of that panel and cannot be removed from the surface.

If it's like the C6, you will need to remove the entire panel to access the speaker and or grill.

Unfortunately, I don't have my C7 here to look at the panel but they are typically held in place with clips. It should be very straight forward. You will need to pry the panel up to remove it however if there are any panels that overlap that one such as the panel that goes across the roof/b-pillar line, you will need to remove those first.
