Can this thing really do all of this? http://www.woofersetc.com/p-10074-leviathan-ii-zed-audio-6-channel-900w-rms-amplifier.aspx It seems to be a little cheap for so much. There's a guy online who says he tested it at 148 watts x 4 at 4ohms and 563 watts from channels 5 and 6 bridged at 4 ohms. he also said how efficient it is, used the word wow a lot. Made in America too.
