Analysis Plus 1.2m Super Sub T JumperSuper Sub T Jumper Allows you to run a single long run of sub oval interconnect to your subwoofer. Simply plug the male end of the T connector into the sub and insert the long run into the female on the top of the T connector. Then connect the 1 ft. sub oval to the subwoofer and the other end to the female on the T connector. This eliminates unwanted pig tail connections of a hard splice.
