you first have to remove the front door panel, the whole thing, then just unbolt the speaker and unplug the wires, and put your new speaker in...there should be screws along the outside edge of the door panel, underneath the cushions on the handle..unscrew all of these, then put a screwdriver underneath the door latch and try to "pop" it out, the door panel should then come off.
