DOB has nothing to do with being a regurgitator.
I was born in '89 as well. Who cares. I simply state that 2" is unlikely since we basically have the same truck, it is added that that box is built to drop low. I giggle and state my system simply as a reference to "lowness" and panel flex, and then someone was a dick to me because i didnt bow down to the all mightly Type-R as beind superior to all things audio.
I imagine that if my cab did flex 2" the rubber gasket that holds the glass in the frame would tear and the glass would partially dismount then shaddar. Ive seen it happen to other extended cab trucks and the cab wasnt flexing 2" to make it do that.
Ive seen systems loud enough to start tearing the glue around the windsheild, crack the dash baord, my own system rattled trim peacies off of the dash, ive seen roofs wave like the ocean, all in extended cab trucks, and never once have i seen 2" of flex with the back glass staying intact.
I too would like to see video of this 2" of flex.
