LOL, yeah, that is a huge speaker and a weird looking guy in the corner. As far as windows shattering...I know that van I posted a link to uses 1/2" thick (eventaully he is going to replace it with 1" thick....I think he said) plex-glass instead of glass windows. I actually got to see that thing first hand since the guy who owns it/made it graduated from the Engineering college that I am enrolled in.
