those amps do best with .7 nominal..... not actual.. actual load at burp, you gonna wanna be above 1 ohm...
the two teammate / friends I have that used those (Paul Nelson, Chad Hines) both ran theirs @ .7 nominal.... both had modded amps..
you're gonna want dual 1.4 coils, and you'll probably not wanna run those amps @ .7 nominal daily.... I'm gonna assume they are modded..
