I think there is a cadence txa series amp that put out about 750 watts on the classifed right now.. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
i have a cadence txa 750.1 at 1ohm it is in protection mode but nothing is visibly burnt on the board should be an easy fix for a nice little amp you can have it for like $15 plus shipping
