Not sure what farad that is. My buddy had a 50 farad and it helped quite a bit when they get that high though it's pretty much a battery then. You can get a batt cheaper than that though just fyi. I'm running my 2 on a sundown saz2000d 2000 true rms and no dimming. I'll be selling mine soon to upgrade to bigger batts.
