Dude...
If you continue that your sub will be junk. That was one of the absolute most horrible unloads I have ever seen.
Please send me your box layout so I can have a look. You either designed that bock incorrectly, way below tuned frequency or simply way over the subs capability.
You can clearly see where it went non-linear in a destructive fashion.
A very scary video for a nice sub.
