I hear you, I'm all for headroom ... top to bottom.
Merely pointing out you may try it first with a normal 20 amp circuit. A couple days ago, I shared some information about residential circuits, etc, that seems to come up quite frequently. I always try to point out that due to the transient nature of music and special effects, that the branch circuit wiring size, 14awg/12awg/10awg, is often more of an impediment than the breaker.
Massive current amounts are allowed prior to a breaker tripping and interrupting the circuit. These amplifiers are quite efficient, and so is an IB aligned sub system.
Here's a section of that information in a recent post;"The main breaker, and the branch circuit breaker, ... and these can both pass extraordinary amounts of current higher than their rated amount. By design, to prevent nuisance tripping with motor loads (which pull huge amounts upon start up), typical residential breakers can pass 7-8 times the rated trip amount, .. for up to a second or more. Also, it can allow up to 3x the rated amount for up to 10sec or so, and up to 1.5-2times the rated amount for a period extending as long as 30 seconds.
So even the smaller branch circuit rated at 20 amps, it can allow;
~140-160amps for up to 1 sec
~60amps for about 10secs
~30-40amps for as long as 30secs
Again, that is a huge amount of current."

You may try the drivers in open air, with the entire signal path in place, and carefully check how much amp the drivers will take, ... this way you can carefully explore max excursion without being subject to full SPLs, since the drivers are in free air. Also, you will explore current draw of the sub system too.
Since IBs use amp power so differently than small sealed subs do, free air testing is really a worthwhile way to safely and carefully explore all the limits at the system extremes ... but without the structural shaking and high SPL craziness that accompanies typical limits testing.
