EricM9104 Posted December 26, 2009 Report Posted December 26, 2009 Looking at re-doing my system once I get a new car (MK3 VW Jetta)... Think a 200+ amp alternator, 2-4 group 31 batteries in back would keep voltage above 13v full tilt, with the amp at 1ohm?

Boon Posted December 26, 2009 Report Posted December 26, 2009 Yeah I would say that would be fine. Won't stay above 13 though. 12.8. Quote 10.x volts fo' life!
