Help me pick an upgraded stereo system for a 2008 Scion xB!?

We got the Pioneer Premium Audio system, but it's just not cutting it in the clarity and bass departments. I'm not looking for a system that costs $2000, but something with decent bass, mids, and highs... a sub, an amp, etc. I'm looking for good quality sound, not just LOUD sound.

I think the best bang for your buck is going to be a Kenwood system, Kenwood has really clean amps, but If you want to spend a little more money then I would go with Alpine...Alpine is hard to beat at any price.
