dual 2 ohm wired to 1 ohm and 2 xs power d3100 in the back and the optima yellow top up front or maybe 3 kinetik hc2400s ?????System I am planning is around 2500WRMS, and I will be running 2 batts;Guy up the street is running a 10k system, and is making it on 5 batts.
3 solid batts might get you by....but I question whether or not that 270A alt can handle an 8100WRMS load
What impedance are ur subs + speakers ?
