Nice setup, I think you're light years ahead of where I and probably a lot of others were at your age (I was doing car audio in college, kind of wish I could have taken that back now). I've got a white light behind my tv right now, I've had a few comments from friends that they think it's cool. I think I'm actually going to try to move to crown molding with cove lighting and see how that works for ambient light, but not right behind the tv.
