SUBWOOFER REPAIR HELP- i punctured my rubber surround on my subwoofer.?

earlier i installed my 2 kenwood 12's in a bandp enclosure and because of the goofy angle i happened to accidentally stab my surround right near the basket which punched a small tear in it. now the material surround is rubber not foam, so should i go to the car audio store and get some type of kit to do this, or hand it over to the professional repair center there? or should i buy some silicone - if so which type. spray adhesive, hot glue, super glue? and again its right near the basket.
