First off, what ports does your stereo system have?
If it has a "line-in" port that looks like you can plug in a standard 1/8" jack (like on headphones), then you need a 1/4" to 1/8" Male-to-Male adapter cable.
If it has an "AV" port that looks like either a "red and while" or "white and black" ports, (like the set on most DVD players and VCR's, White, Yellow, and Red) then you need a 1/4" to AV Male-to-Male adapter cable.
Whatever says: "Input" That's the kind of cable that has to plug into it.
If your lucky to have a stereo system that has a 1/4" port, then you can use a standard "Guitar cable" to plug into it.
I really hope that this information helps!
