Yeah your tuning will change since you are changing the volume of the vehicle.As for attaching the box to the car I have heard you want as few points as possible to reduce vibrations through out the body of the vehicle.

once you have the wall in play a 12 in a sealed box and figure out the loudest frequency with a sealed sub in the available airspace. then port your wall around that frequency, though the tuning goes up a few Hz with several thousand watts on woofers due to the loading of the air in the vehicle.

If you get really into it the termpro guys have tons of experience with buildign walls and getting your tuning right. Some here have the expereince, and some dont. I would get as much input as possibel if your going to compete.
