Also, at what supply voltage does it make 3000W RMS? 16VDC? That is important to know, so you don't waste your time trying to get 3k at 12VDC.

A battery bank is almost requried for that much power, with one or more large HO alts. Sure, you can try to get that much power without the electrical infrasturcture, but the voltage drop will be too great and you won't ever see it.

Are you burping or trying to sustain that power level with music? Is this for everyday listening or SPL competition? What is your objective and goal?
