Build an Orion Demo Truck, think I have Pictures somewhere on it, but it blew the two side windows right out of the truck, 8-15" Orion NT2 and 2 Orion Concept 97-3 and a Concept 97-1 you do the math 
It was a chev full size this is going back probably 6 years and it hit 155db with the windows out.... it peaked close to 160 but never got a real test cause the windows gave out.

I have 1 12, and I shattered all my windows.
With a bat.

Unreal audio that truck was built by our crew at acoustic services led by mark feeney. It was at audio thunder. The truck was owned by one Mr. Fagundes. How did you like the duck tape that we held the window in with at the end. Hit the cement floor and didn't even smash. Just flew straight out.
