So I bought some used DD 9917s off CACO and apparently they were just reconed. Well, I had a box built for one of them just to try it out and I started to play it in the car and it wasn't exactly very loud and literally after a minute or so, the sub completely locked up.
It was wired to two ohms @ 3000 watts which is pretty much nothing for a 9917.
So, after that, I hook up the other one. I notice the strong smell of a burning sub after about 20 seconds of playing it loud then about 2 hours later it starts making a sound like a spring vibrating or something. This one isn't blown YET but I sense it's damaged. Any of you guys have experience with something like this happening before?
