I have a pair of older 15" kicker comp cvrs that used to bang hard... I got them off of a friend and he left them by a window for some time. So when i got them the rubber ring around them looked brittle. After hooking it up they hit really hard and i managed to start tearing them around the ring... the coils are all good but im afraid to bump them and cause more damage. So I was wondering if there is a way to patch them or do i have to send them off to kicker? Anyone with info?
