How low can I go with a crossfire vr4000d (voltage)?

[da box king 10+ year member]

I have a 150 amp alt, and a g34 up front, and 2 g31's in the rear. With 2 pos 1/0 kicker runs and a neg run, and 4 guage to all the amps(thats what they take). I'm worried about voltage with the crossfire as I heard they don't like low voltage..I will watch my voltage but how low do you think I cna go to be safe.. Late I will get a mecham 260 amp alt...but any input would be nice

in general just try to stay above 12, anything less and you need to either turn down your gains or beef up your electrical some
