I've recently become a fan of Polks MM line. Good midbass performance and smooth tweeters, slim mount design too. Pretty sensitive so you can drive them off the OEM radio setup but they also seem to handle power well as I'm running a set of MM6501 with around 100 watts off a Kicker amp in a VW Passat. Speakers (especially tweeters) are a pretty personal choice so I would try to listen a local shop if possible.
My equipment list is here. Playstation Network ID = jmii ...that's JM roman numeral 2
