Re: No compromises front loaded double 18” cab
Before you can look at output power, you should look how much power you can get into the amps.
Here in Germany we have aproximately 4kW long term input power for single phase 230V/16A feed ( which I can get everywhere ).
My rule of thumb is to expect about 8kW short term output power for sub application ( still music, not welding ), if the amp is class D, has high efficiency and PFC.
For 2 Ohm operation ( if the amp supports this ) these 8kW are diminished, because efficiency goes down, and are distributed over 8 drivers ( 8 Ohm each ).
For me the conclusion was to buy amps optimized for 4 Ohm operation and at a prize, where I can buy two for the prize of one big boy amp.
As I understand the power distribution in USA presents you an even more difficult task
