Well after listening to to what everyone has to say about this I would have to agree with heamphyst and Id say its not all its cracked up to be and I wouldn't waste $20000 on it

See? I was right. There is NO WAY, on a continuous basis to exceed 100 percent efficiency, with a SINGLE power supply. I understand now, the "hybrid" option, but this isn't new. Bob Carver had multi-rail voltage, "smart" power supplies YEARS ago... The 1.5T was a REAL 750 watts per channel, PEAK, and the transformer was about the same volume as a pack of cigarettes. He used the same capacitor bank cheat as this amplifier does.
This is the SAME trick RF is now pulling with this amp, except they are CALLING IT 15kW, and it ISN'T... Drive this amp for too long, at those power levels, to where the power supply eventually becomes exhausted, and leave it all up to the 12v power of the car, (which BTW is 300A*14.4v=4320watts in, / 4 channels = 1080 watts per channel - all of a sudden - with the volume control WFO!) and it's gonna sound like crap... No additional voltage for headroom... And being driven THAT hard, with the high-voltage power supply all of a sudden empty, major clipping will ensue.
Nope, IMO, RF is falling into the same category as Audiobahn as far as the honesty of their power claims are concerned. It's NOT a 15,000 watt amplifier, it's a 3500 watt amplifier - for 20 Grand!
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

20 grand is a lot of money for an amp. so is 7000 $ for the jackhammer, no thanks i stay with my 4 12" and my 160A Amp.Rockford Fosgate T15kW - Page 3 - Last Post -- posted image.
