If your wanting to change to a little more toned down and sound quality setup then a single 12 facing back is the way to go.
As for the fronts use 6.5's. As was said before components are the way to go in this car (easy install and sounds the best). If money is tight and the speakers you already have are coaxial you can run them for a while, until you get components, as they are still better than the stock equipment.
You didn't mention anything about a new head unit?
