This is for connecting the Teac subwoofer system to the main unit. There are different 9 pin configurations and this may not fit your non-Teac system. Please ask for help. 15 ft length. We also make a 3 and 6 ft version. Poly bag packaging. This cable will NOT work with Bose, Korg M3 or Sanyo Home Theater systems. We have cables for those too, just not this one! Lifetime warranty against cable defects. | |||||
