The pressure differential would not be enough especially with how we have fresh air coming into our cars. Pull off the plastic around the battery and you will see a large inlet. There is no way enough pressure would build up in the car to cause damage to that seal when you have that air duct venting to ATM.

If that's the case I would be worried about running my sub in the car with the windows up, as that thing surely pushes just as much if not more air in a "sealed" cab.

If you can find me a example of a small car with a frame all around the window that still has the window open a crack when you open and close the door ill have to believe you, but I dont believe that is the case. If it was your ears would pop everytime you closed the door.


This is all my opinion, as I really have no facts other than my window hitting the car to back it up.
