I'm thinking about buying these (3-way). I've heard they are the best speakers out there next to the JBL Power's and the Infinity Perfects.

 

I have Infinity Kappas in my Integra, and I love them. I've never heard the Perfects or the JBL's so I can't speak for them, but the Kappas perform very well.

Do you have a subwoofer in your car? These speakers are good for mids and highs
