I bought 4 sundown e 12s and I have them installed in a 02 Silverado. They are all D4s, wired at 0.5 ohm. I was playing them and one rattled really loud and froze. I looked as if the coil had been welded to the motor and was seized up. I cut the soft parts out and the coil was perfectly fine. I looked closely at the inside of the motor and the gap was not even all the way around. It was like the slug in the center had shifted over and it will not move back. How do I fix this, who can fix this, and how does this happen? Any info would be helpful. Thanks.
