yes sundown. my saz3000d pulled just about the same ratio of amount of current as my hifonics does.
if you have a decent electrical system you can keep the voltage up. with 2 125ah batts in back and a 70ah upfront. i only dropped to 13.5 from 14.5 when running my 2607d at .5ohm. now with the 2 of them i drop to about 12.7 while running them at 1ohm each
