I have a pair of phoenix gold x600.1s birthsheeted 879rms on one, the other I don't have the box and paper work for but they all birthsheet out around the same. 800+ from 1-4ohm if you bypass the xeload they'll do more. I'd only do that at 2ohms or burps possibly lower. if the pending trade falls through and your intrested lmk, I miss my old genXX a little sloppy but lots of power I could use to run a single load //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif . I have power, but on two loads //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif don't like running one amp per coil, one of my subs is sitting with a single coil blown from the last time I attempted that lol.
