Trying to Kill the Beast

Rockford Fosgate RFR3110 Power Series HX2 10 Subwoofer. Amongst 100 other problems this gay ass thing had when I got it in the mail, it s got a leaky dustcap and the coil is all messed up and for some reason, at a certain tone, the cone and coil assembly just shoot straight up and get stuck this is my attempt to put the beast to rest before I recone it :D
