I would put two 6x9's in the back and like two 5", one in each door. As for brands and affordability it depends on if you want better quality or better power. I am a big fan of Pioneer and you can get some good speakers in that range from best buy along with a Pioneer amp with Tri-mode there for about what is in your price range. I wouldnt bother with the tweeters in the dash, i think that would just be pointless. If you are looking for that good of sound range get some good 4way 6x9's.
