I think 4 x 3-3.5" fullrange with good passive crossovers and sound deadening to stop the door's buzzing and you got a much better sounding sound system with careful selection of parts for less than $150. It's also a good starting point for upgrade and you can easily add to it.

I have the $12 speakers listed by soundman with the 800hz inline crossover and it's a noticeable Improvement in sound clarity, but the buzzing doors begin to get highlighted. This is where the sound deadening comes in. The factory woofers are actually not bad looking and the output matches the new dash speakers well if you remove the door buzzing at higher volumes.
