650 and 600 bucks?!? That's a pretty reasonable price I think, I'd go with the Utopia's since they are only 50 bucks more, and plus not many can say they have Focal Utopia's in their car (assuming they've ever shopped for car audio outside best buy, cause to those people PIONEER ROCKS MAN!)
i say get the utopias also. $50 ain't nothing if you already that high in price. you'll have the best speakers out right now. and for you gotsnoboost. i love my pioneer speakers. hahah.
