wiring subs

How would I wire up 3 dual two ohm, or dual 4 ohm speakers... I used the impedance calculator, but it is making my brain hurt. I need about 400 watts for each sub, so 1200 watts rms total. And I need to know mono what kinda ohmage I am looking at, and weather I need a mono amp or a 2 channel bridged or whatever... This is making my brain hurt. But the subs are going to be 3 ED 13Kv's So pick me out an amp to go with them. I am wanting a class D to save on amperage, but if I have to go with an a/b because of the ohm load then I will. Thanks in advancefiberglass reminds me of peanut brittle... but fiberglass tastes better!

ok somtimes I feel like a sped.   I figure if I get the dual two ohm versions I can strap them all for 4ohms. And then tie them all in parellel to a monoblock and it will render a 1.333 ohm load. Does this sound good? Also, if I get a monoblock that is only 2 ohm stable will it underohm protect on me. Or should I just get one that is 1 ohm stable and not run it to it's full potential?fiberglass reminds me of peanut brittle... but fiberglass tastes better!

Use the woofer wiring wizard over in the left column and save those Excedrins.  And if you want to put a 1.33 ohm load onto an amp, it will have to be 1 ohm stable.  Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
