That's going to give you the most power possible. I'm not sure of the specs of that sub, but I'd be surprised if it could handle what that amp puts out, probably will shoot flames. Definetly turn the gains all the way down. What kind of box are you using?

yeh i just looked at those diagrams myself. i know my amp is pretty serious, but people say the sub is underated and should hold its own hopefully. i have a fairly big box right now, that holds my Treo. But the specs for this sub ask for 3.2 cu.ft. I somewhat forget how to calculate the cu. ft , can someone give me some dimensions so i can get a rough estimate if my box is big enough. thanks for the quick reply

L X W X H (in Inches) =x
Then Divid X By 1728 = Sq Ft
