So i decided what I am going to do...
Sails: Polk db1001 Tweeters
Front Doors: Polk db461p 4x6s
Rear Deck: Tang Band W69-1436 6x9 woofers...

Amp for the 6x9s: Rockford Fosgate Punch P325.2 (2 channel 80 WRMS)
Excludding installation costs, it will be like $350. I think it will sound good and is a good price.
