Without the make and model of your stereo speaker system I can't give an exact answer.
If the speakers are passive you can connect them to the RCA speaker level output on the subwoofer. The center pin of the RCA plug should be the plus speaker connection.
If they are active you would need to use a speaker to line level converter.
Cheaper gear uses RCA connections for speaker terminals, which was not what they were designed for, so it seems like you could just use an RCA cable but that could overload the input of the powered speaker, cause distortion, and maybe damage the amp in the speaker over time.
