DDJ SB AND 5.1 SOUND PROBLEM

Hi, i want to buy a ddj sb console, and i m using a Genius SW 5.1 sound system, i understood that using this kind of audio system i will never get sound  from all the speakers (including subwoofer) when i m using ddj sb console. is there any chance that i could make at least the subwoofer + front speakers to work ? on the back side of my subwoofer i have AC-3 ( 5.1 ) INPUT 1 with front surround and cen, AND 2-CH INPUT with TV, TAPE and CD/VCD DVD ( 2 CH) thanks !
