Of course it's pressurizing the cabin but what Dukk meant is the sub creating ENOUGH pressure in the cabin to 'restrict' the movement of the cone? I don't think a single sub in a non-extreme SPL car is going to do that.

This article has the answer. It gets a bit complicated near the end. It has to do with standing waves, resonance, cancellation, harmonics and modes.

No, the cabin pressure isn't really enough to restrict the motion of the woofer. What restricts the motion of the woofer alot more is the small amount of sealed air behind the woofer.
