Gorilla tape should work just fine if you dont want to recone it and still be able to use that sub. Id recommend using a heat gun or a hair dryer to heat up the glue from the gorilla tape and either use a roller or just press with your hand enough to make sure it sticks well. prob be best to do both sides of the sub to make it a bit more rugged.Its either that or reone or replace the sub.Gorilla tape is about $6-8 bucks a roll. pretty good tape IMO
