coming from someone who has a giant fiberglass box made by fox as well that goes from both sides with two 12s at 1k+ watts RMS, its pretty interesting, in my truck it makes the front seats vibrate like a **** and broke my overhead console!
now the back seat, where the sub is, you can watch the seat flex as much as the sub does....
and if you want to have fun, put a female back there
my neighbors came over to see my truck one day and experience the bass up close and personal, and the wife and daughter both REALLY enjoyed it, at one point he actually walked away from my truck saying "i cant see my daughter look like that and make those faces, and a dad is never supposed to see that"
and then when his wife sat back there about 45 seconds into the demo, i felt a hand grab my shoulder, squeeze hard and then i hear "dont turn it off till i let go"
so naturally i turned it up the bass knob from 5% to 50%
she drew blood from my shoulder from digging in her nails...
that day was a good day!
