here is a tip that worked good for me. in the doors if you will take the grill that comes with the speaker and cut the meshing out flip it beveled side toward outside of car, you can with most speakers gain the extra. you will have problems getting the bottom to clip in, go to home depot (or equivelent in your area) and get some invisible screws. it is simply a screw with a cap, run it in to pull the panel down, and you get all that you want with a factory look. i used pioneer 3-way 6.5's, nothing cheap. you can also easily modify to get a 6x9 to fit in the back and get a amazing difference in sound. hope that helps
