could this be caused by running a dvc sub off of seperate channels of the amp or maybe having the coils 180 degrees out of phase from one another?

No. Not unless the coils are on opposing edges of the cone. The voice coil former would be crumpled like a piece of junk paper.

That may be a passive radiator but it still doesn't explain the craziness, and is contraindicated somewhat by the presence of a nearby port.

What is that yellow thing in front of the speaker?

The unit is mounted in a car boot and there a reason that is not clear in the video why this cone motion is so twisted and warpped, any other ideas tho?

omfg

someone's playing a joke, that can't be a real functioning sub.
It goes all sorts of angles of axis. Unless this is some new two axis sub, not.
"stop motion video" comes to mind too. It may be a blown driver and they cut off the coil former and had their buddy push it in and out and speed up the video. Of course I really have no clue I'm just guessing.

I am 100% positive that its someone moving the cone from the back side and the video is being played back at a higher speed. It does look quite interesting though.
