John - thanks for the reply. I can see the two screws for the speaker, but don't have any tools to get up in there to get at them without removing that panel as far as I can tell. Maybe someone put some kind of aftermarket panel on mine. It's carpeted the same as the interior and is just too big and bulky to allow me to get at those screws.
