OK pay attention this is hard to describe with words. You can't get 2 ohm with this. You can only get 4 or 1 ohm. But remember (this is where it gets confusing) when you bridge an amp, the amp "sees" 1/2 of those little ohmies. Reason is - you are sharing channels and so the left channel sees half as does the right. What you need is to wire them in series-parallel.

wire 1 - from the amp'* positive terminal go to sub 1 coil 1 positive.

wire 2 - from sub 1 coil 1 positive to sub 1 coil 1 positive.

wire 3 - from sub 1 coil 1 negative to sub 1 coil 2 negative.

wire 4 - from sub 1 coil 2 negative to sub 2 coil 1 positive.

wire 5 - from sub 2 coil 1 positive to sub 2 coil 2 positive.

wire 6 - from sub 2 coil 1 negative to sub 2 coil 2 negative,.

wire 7 - from sub 2 coil 2 negative to amp'* negative terminal.

This will result in a 4 ohm load which the amp will see 2 ohms.

To get a 1 ohm load, connect all of the positives to positive and all of the negatives to negative.

hope it helps

The only ways you could get a 2 ohm load is to only use 1 sub and wire both the pos together and both the negatives together and back to their respective terminals on the amp.

or
Wire both subs in parallel but only use one coil on each sub.

or

Buy two more subs and wire like the post above, except that you would carry it over to the new subs and bring back the negatives from the last sub.

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

KEOTOK is correct. You cannot get a 2 ohm load from 2 subs with dual 4 ohm voice coils, if all coils are used. You can only get a final load of 4 ohms or 1 ohm with what you have, and if you are not carefull you can wire them out of phase and fry them. Check out the Wiring Wizard diagrams on Rockford'* site in their tech support section. www.rockfordfosgate.com/rftech/wiringwizard
