Well, i already got the fronts (his Diamond Audio S600s) from that install that you heard since he replaced them with some Focals (IIRC). I think we heard it at the meet with the Diamond Audio sub, so i'm sure it would still sound great, but he threw me for a loop saying how bad it sounded. Especially since i've seen and heard his Adire Brahma. That sub is F'n AMAZING. You should check out some of the videos on their website. I wish like hell i could fit that sub where i want it.
