My sub blew?

[350gt]

I put it on as I normally do and for some reason a few minutes later I heard some rumbling coming from the speaker. It is my second sub in the room and it a JBL venue 10, it is running from a Y cable with my def tech supercube.
Whe I inspected the speaker I smelled something burning and pulled the rca out of the sub. As I did I felt air pressure from the input and yanked it out. I then unplugged the power cable.
The rca cable looks fine but if you look straight into it the surface looks black like if it burned. The sub smelled burned for while but has since gone away. I plugged in the sub and it now gets no response, I wasnt expecting it too but just wanted to be sure. The power light comes on but thats it..

Anyone know what could of happen?



Oh and my other sub is fine......thank god..LoL. I dont mind losing the JBL but not my DEF tedh.

I was loving the sounds of two subs though...



Details: my sub was turned alittle more than half way to keep up with the other sub.
