thx to all who replied here.
I'm looking to go bang for the buck so following KoneKiller and Mazman. I think I'll use the Sube upgrade w/tweeters.
Anyone have a nice $400-600 headunit that has some power and looks right. I'm thinking Blaupunkt or Alpine. Is the Sony stuff any good it looks cool -but that may be it. I don't need thumpn Bass or ear splitting volume. MP3 disc play back would be nice but not ness.
I'm not lazy just willing to listen to those who have done some research.
