OK heres how you get a 2ohm load with rf he2'*
1.take 1 sub and connect the+ of one side to the - of the other side,then do the same foe the - to the + .(you should have a cross (x)pattern)
2.do the same for the other sub.each sub still is at 4ohms
3.now,take the + of both subs and connect to the + of the amp.do the some for the - .
4.adjust your gain on the amp ,and start bumpin'
5.you might want to consider adding at least a 1 farad cap,those subs will draw alot of power.
let me now how it sounds
