If your into music and appreciate clean audio, then nothing beats a comonent system. In a component set, the tweeters are mounted separately from the woofer allowing louder and more powerful mids without distortion. The Infinity Reference 6010cs are a premium and affordable component set that wont dissapoint.
They are best run with an amp, and complimented with a subwoofer.
As for now, I ran mine from my deck and they still sound great. If you run them without an amp, they will distort at high volume levels, because there is not enough power from the deck to provide a clean signal.
I run the 6.5"s In the soundbar and placed the tweeters in the dash of my TJ.
I highly recommend them to anyone who wants premium audio without spending an arm and a leg.
