I have/had (currently removing) Alpine everything, head unit, with 6" in the doors, and the rear cut for 6x9's with a 10" sub and amp in the trunk. I like it, it sounds really good without being overly expensive.
My new system is a live jukebox/karoke machine with a great selection of the classics, but it will occassionally goof on the lyrics, and doesn't always quite have the tune right. It will take requests, if it's in the right mood, and doesn't pretend it sounds better then it is. If it has a cold, it takes the day off.
