thats right, because i can tell you first hand a single pa 3000db of mine tested on a quad dd 9915 surely didnt have a problem at .5 load for a solid 5 minutes. Its a solid amp and the lanzar opti series is the best amp they offer. My guess is it would give you 2k at 1.5 ohm load, but I dont understand why you cant drop it to a even 1ohm load?
