Pyramid= Shi't. If you want an amp that'll make RMS power like that, you are looking at like USAmps, US Acoustics, Zapco, MMats, EQ Shredder, etc. The Zapco C2K-9.0XD retails ~2500 bucks, and it makes 2000 RMS 2 ohms bridged, and that is underrated.... Never believe any amplifier manufacturer who puts the max wattage on the amp.
P.S. For all the knowledgable people, I know there are other ~2000 watt RMS amps out there, the Zapco is the only one I could think of at the moment...
