Best bang for the buck imo: JBL 1200.1 I've blown two audiobahn 15"s with it, and before that hit 143.8 in a sealed box. I've had mine for three years without a hiccup. if your planning on running those 3 mtx's your gonna need a reliable amp. alot of them aren't 1 ohm stable and that should be what your amp will see. (assumming the subs are 4 ohm SVC's)
