So its an 04' model? I had a 04 12L7 the cone broke off from spider. Yours prob did too or is in the process pf doing so... Pull the sub outta the box check all around where the spider meets the cone. This is what happened to me 3 times(I'm hardheaded). If this is the case and you want to try and repair it, get epoxy for plastic at walmart, autozone wherever but the longer the set time the stronger the bond will be. ie 60min epoxy would be stronger than 5min.
