I put in some Kenwood 4x6's in the fronts. They stink. Even after soldering in some capacitors to filter out everything below 300~ hz, they pale in comparison to the Infinity's I have on the rear shelf. So I'm going to find myself some Infinity 4"s for the dash.

Also, it takes a lot of cutting to get the 4x6's in there. And once you do that, no more warrenty.
