Id look at the alpine type x. You can get them online for about that price. You can probalby go to a good guys and listen to all three back to back. Ive herd some good stuff about the pioneer revs. I had some old polks ex 2's and they were ok but didnt feel they were particularly special. Id also put more money into the front speakers and jsut buy some cheap coaxils for the rear if you need to. What is the budget?
