This amp has never seen under 15.0 volts and it POUNDS! It is an extremely large amp... I have had a DD Z1A, and a cadence zrs-9000d, and an autotek mm4000.1, and this thing is just as loud (if not louder) to my ear as any of those. This amp is an absolute beast on my two treo ssx 18's... It's a true 2-ohm stable, and will accept 17.5 volts of input
