If you've not looked inside one of these you may be surprised. Grill is at the front of the door, speaker is at the back, a tunnel system moves the sound, and its really hard to put anything but a 5-1/4" speaker in the factory mount. Consider buying the door card and using one of the available patterns others have designed for more common speaker sizes, and the possibility of 2 or 3 way door speakers.
