internally regulated. Irragi 280amp and 2 kinetiks. no it doesnt always sit this high, i just snapped the picture one day. everything effects it (temperature, whats running, ect). 14.7 is consistent though
mine never drops below 13.7 but i still gotta redo some wiring under the hood. one of my ground wires is like 8 gauge battery cable i got off a lawnmower //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif but my alt wire and everythng else is RF 4 gauge. running 600rms i seem to do fine with no dimming or anything
