Your setup pushes all the pressure into the cabin...thus why you don't experience much rattling. In a sealed enclosure, the box rattles, and the front of the sub rattles (obviously because of the sub), and anything the box is touching , also vibrates/rattles. Also, depending on the sealed enclosure, all the pressure is stuck in the trunk. I have a zenclosures box and it pretty much sealed to the back seat. I do leave it about an inch and half away from the backseat to get some flow into my ski pass. Sounds great but the trunk rattles alot.
