Yo, i just got a 12" MTX thunder 8000 4 ohm dual coil sub and need an amp to power it. The thing im confused about is which one i need, in terms of power. The sub is 400 rms and 800 peak. So what i wanna know is what amp i can get. I was told i need to get XXX rms @ 4 ohms bridged. Is that correct? I was looking into buying a Hifonics zxi6006. Would that be the correct amp for this setup?
