like NDMstang65 said, that might be too much, but as long as you have the gains set properly, it should not be a problem. the FI Q is an amazing sub, mines is only getting 800rms or so, and its friggin' loud as hell.
my next setup will be 2 12" FI Q's with at least 2000rms //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
