Our maniacal rabbit got out of his cage and made a straight run for my cable.... he's lucky it was a passive subwoofer So now I've got a bunch of teeth marks that split the outer casing. The cable runs behind the walls and under the flooring so I cannot pull another one through (I am an idiot for not putting conduit down there). My understanding is subwoofer cables have an inner core and an outer casing, both of which needs to be connected, but can't touch. Someone correct me if I'm wrong.... Is there a simple way to splice this type of cable ? Thanks !
