speaker grill coverings

ok, thank you accord man for answering my last post, i'm glad someone could shed some light. I have another problem though.
I've recently tried to remove the grill covers on my speakers, but they don't come off. I found out that the front speakers are attatched to the whole door panel, and i have no clue on how to take the door panel off, or if i even should. I succeeded in popping off about half of the door panel but i can't seem to get it off from the window area. Does anyone have any suggestions?
