My buddy has an MTX Thunder 8000
There isnt a knock, and no scraping when i push on the cone or anything
He says it only works at high volumes, i hooked it up before even knowing that and nothing happened (hooked it up to my amp)
It appears the coating around the tinsel lead melted off on part of the positive lead, so idk if that could have caused something
Here's a pic of the lead, sory for the grainy image, its off my blackberry

He had it getting around 400 watts from an infinity reference 1600a i believe
Also, would that amp kill my sub if i bought it?
I have an infinity kappa 102.7- 300 watt rms dvc
that amp does 600 at 2 ohms, so it would be getting double power but i'd set gains modestly
