My simple mind says that to do this, you'll need to drive the woofer way beyond its BL limited xmax, toward its true mechanical xmax (sort of like a slingshot effect). Along the way, you'd generate lots of odd order harmonics, which would boost the spl.
Did the 147.3 come at the beginning of a burp, or did the system build up to it? I wouldn't guess you could play it all that long at that power level.
Don't take any of this as bashing...I'm just curious.

Sorry, not local. I'm from chicago.
As for the enclosure, its about 2 cubes and uses aeroports (
Welcome to Precision Sound Products!)
When I burp my vehicle, I start with the volume lower and then roll it up. If I try to burp it full tilt right off the bat, it usually makes the sub bottom out hard, something I never want to do again.
So yes, I am pushing the sub to it's mechanical limits.
2000 RMS on a 500 RMS rated woofer tends to do that.
