This cable will convert the 3.5mm earphone jack into RCA cables. With this cable you can listen to your portable audio device (walkman, ipod, ect) through your (home, car, or motorcycle) stereo system. 

The cable is 6 foot long, one end plugs into the 3.5mm earphone output jack of your portable audio device, and the other end has two RCA plugs. If you already have your own speakers, and an amplifier, then you will need this kit to use your Portable Audio Device with the speakers.
