If you're not going to run an amp, it doesn't matter too much, Circuit City often times has Polk buy 1 set get a 2nd for half off. The best speakers in the world won't sound good running strictly off a head unit only. But since you have $100 to spend, quality is mostly a moot point.
For any price range I recommend Polk. I have Momo components in my Taurus, got them for 199 off ebay *retail is about 350'ish* they ROCK! the cheaper DB's are damn good for the price too.
