i decided neither of them. i want to do a quad 8" setup so i just ordered 4 Massive Audio Pw8's, rms on them is 200. lower than what i wanted but max output is around 400 so im hoping to be in the 1100-1500w range. any suggestions on an amp for these? i seen some Lanzar Vibe amps rated at 350w x 4 @ 2ohms but im sure it was overrated since it was only around 220.00 for the amp
