Now that's an amp, that scares me just thinking about how hard that would hit.
>>4 guage power and ground directly into the amp? What are you talking about it says "Gold plated 1/0 gauge power inputs".
To answer the first question: It would cost alot but I would run 3 amps, one to each sub. Find amps that run the subs to peak RMS power. Then you will hit HARD. I always say that two little amps are better than one big amp. Does anyone disagree with that? Hope what I said helps.
