4 6x8s under 100bux, plus questions

[Mustangless]

I am trying to get a little better sound than I have now. I replaced my stock radio with a pioneer deh-p3700mp and it sounded much better, but now I need more.

These

should I do those all the way around? Or should I get something different for the front or back? Wouldn't something like that be too bassy for the doors?

How well would 5.25 fit in the doors like these here

Would it be better to get those in the front doors?

Neither of those should be to bassy for doors. The 5 1/4 are small and most likley wouldnt have much bass. I have 7" in my doors and they arent to bassy. i would choose the 6x8 between those 2. If you go with anything other then the 6x8 you will have to build a mounting plate for the woofer.
