I got a great deal on 3 JL audios and a kenwood 11 channel eq. Two of them are 8" subs and one 10" sub. I decided to put the 10" sub with the box in my car. I think when I went to test it though the surround came loose. It looks to be just from age though because it didnt rip or bust or anything like that. It seems to have come unglued. The JL surround seperated from the cone as if the glue just got old and came a loose. I really want to keep this sub setup because for one it was dirt cheap and two, I like the way it sounds. What can I use to seal this back together?
