If you're powering a 4 ohm load, and you produce 50 volts:
I = 50 / 4 = 12.5
W = 50 * 12.5 = 625
You can simplifier by using:
W = V * V / R
So, if your amp can only put out 50v, the maximum power potential with a 4 ohm load is 625 watts. Now if you're powering a 2 ohm load, and the amp can handle it, the maximum power potential is 1250 watts. Most amps are less efficient at 2 ohms, so you will not quite get that same power output, but that's the general idea of how it works.
Now if an amp is bridgeable, and you bridge two channels, you're essentially doubling the voltage potential.
Even though I've been all about ohm's law, both vocationally and avocationally, for the past few decades, it's always nice to freshen up
Seriously though, I was unclear as to what you're issue was wrt;
They have some serious voltage potential so I won't be stuck fighting 4 ohms per channel.
Nor did I understand "fighting 4 ohms per channel."
higher impedance loads require a higher voltage swing to generate current.
Never, have I read anything remotely like this wrt amplification and loudspeakers. My mistake,....I see now, with your subsequent posts, your needs.
Regardless, moving on.
Nice move on the amps, I'm glad you're addressing the line side of the amplifiers as well. This epic LF rig, doesn't need any potential bottlenecks, as it may have before. You keep taking steps forward, system and room. Where did you feel you were, wrt approaching driver limits? Where will the new wall power, amp power put the rig wrt to the same limits?
Were you power limited before, and you're moving more toward driver limited?
