Can you put larger speakers in without too much trouble? Or maybe just larger in the back? A 4' speaker is not going to be able to pick up close to all of the frequancies that are in a song, as a result no matter what you use its not going to sound all that great. I like the Reference series speakers as well, and recomend them to you. But, I would find a way to fit the 6' speakers in there, in the end you will have a much more well balanced audio system IMO. As far as head units I have a JVC KD-AR7500 in my truck and have liked it quite a bit, but it does freeze up every now and then. Other then the freezing up every now and again it has given my zero problems.
