Lokuno, he buceado un poco por internet y encuentro lo siguiente. si este es tu modelo, el sub tiene entradas de alto y de bajo nivel (RCA), es decir que lo puedes conectar directamente con un cable RCA-RCA.

More on this product review
The black vinyl-covered medium-density fiberboard sub has a black, perforated metal grille covering its front panel and front-mounted port. The sub's 8-inch cellulose/graphite driver and 100-watt amplifier are hidden inside the cabinet. It's a relatively large subwoofer for this type of system, especially compared with the tiny satellites. The sub's connectivity runs to stereo speaker and line level (RCA) inputs. Size-wise, the sub measures 16.7 inches high, 9.6 wide, and 16.5 deep.
