for the front ones, you just have to pop off the speaker cover. you basically just pull on it, it is held in by 3 little clips i think. there are 3 screws that hold the speaker in after you take off the cover. you will need a small screw driver for the top one, its a bitch. i just left that one out i think, b/c the speaker was held in firmly enough with the bottom two. for the back ones, you access the screws from the trunk. there are 4 screws for the speaker cover then you can undo the actual screws for the speaker bracket from inside the car if i recall correctly.
