C250 coupe - blown center speaker




My car is gonna be down for at least a week, so I want to know if it is possible to pop off the grill on the dashboard to access the speaker? I'm thinking I'll just disconnect it for the week and reconnect it when I bring it back. I don't want to ask the dealer for a new rental over a blown speaker...but it is annoying.
Any ideas how I can disable this speaker manually...or electronically if it is even possible (other then my trick of using the FADAR button).
I already tired toggling between logic 7 off/on and it doesn't make a difference.
