For instance my amp puts out 400wx2@2ohms bridged and im using a 400w rms sub (jl w6v2) which is dual 4 ohm.

So would my equation be V = sqrt (400x2) or V = sqrt(400x4)?

I answered your PM.

You would want to use the actual ohm load that the sub will be wired to. so sqrt(400*2)
Just remember what i said in PM...if your amp isnt 2ohm stable I HIGHLY recomend that you do NOT run it at that low of an impedance.
