I've heard of people just hooking up a better amp to the factory 8" speakers with decent results. There's also a shelby/kicker direct fit replacement but I probably wouldn't bother with that.
The problem with that spot is that even though it sticks out pretty far there really isn't any depth for a good speaker to fit. If I did a stereo build I'd almost want to put the regular door panels in and ditch the 8" setup.
