crutchfield will sell you a set of car stereo installation tools for like 100 bucks, including an ingenious device called a skewdriver, which is like a toilet snake with a bit on the end. or, see above post. unscrew any screws in the doorhandle first, then start popping out the fasteners at the bottom of the door with a straight slot screwdriver,(watch your paint) the lift the door panel up and off. disconnect the electrical connections instead of letting the panel hang from them. you'll be glad you did......the speakers will be held on by six sided hex screws, about 7mm i believe.
