I was on another forum and a member stated the following (we were discussing why our explorers roof flex, and I responded with my new crx style box might cut down on the amount of roof flex)
"the roof is flexxing due to the variance in air pressure, which is bass by simple definition.
unless your new box manages to NOt change the air pressure in the car, which would mean no bass... the roof will always move.
less subs, or lower xsus subs can decrease that pressure, but that also will yeild a decrease in sound pressure, or loudness, or dBs"
Is this true? Does sound pressure have a direct relationship with the amount of flex?

Yes, that is true, the amount of flex would depend on the SPL you're hitting, in combination with the frequencies being played. If you are playing the resonant frequency of the roof, then yes it will probably flex
In my place, I have these wooden box shudders on my windows downstairs, right by my guitar rig. I can play pretty loud without them vibrating UNLESS I hit a low "G" in which case they vibrate like mad at even lower volumes.
