inside door handle that opens door,plastic cover pull off one screw here.

Did you remove the plastic panel that covers the mirror assembly? After you remove the door handle, that would keep the panel from being lifted off the tabs. That piece can be easily pried out. Speaker replacement is almost as easy.
This is the kind of door panel I have. I can only access the bolt that holds on the door handle and two body clips. One under the mirror access, the other under the other piece across the window from it
