The Phatnoize was sold to Kenwood. My suggestion is if you want to put one of those in, then get a compatible kenwood head unit.
two of my friends have phatnoizes and i am very envious of them. That's a sick setup. but for the $1400 it'll set you back, i'd rather ditch the heavy stereo equipment and throw it into suspension and performance upgrades.
but what do i know? I'm still rolling around in my old n' busted E30
