I believe it's more than just the baffle - the lower panels of doors with factory speakers are actually bowed out into the cabin to get space behind them (while letting the window descend). When I looked into this a while back, it was the difficultly of getting those matching panels that put me off adding speakers to the doors. When you add in the time to disassemble / reassemble the doors, the difficulty of passing the wires through into the body, and - as you're asking - locating or making the mounting baffles, it turns into a pretty big project.
