[who-dat]

2 days ago I started to hear a rattling in my sub. I checked it later that night and near the bottom of the coil, the cover that has like a glue seal around it, is torn half way around.

Would it be okay to completely just reseal this?

the dust cap? the center of the cone? if so then yes you can just seal it back down, as long as nothing got in under it.
