How to Connect a Boombox to a Subwoofer

Connecting a boombox to a subwoofer can add low-end frequencies to the audio being output by the device. In order to establish a connection between your boombox and your subwoofer, your boombox will need to have an RCA Line Out jack. Connecting the two devices by way of the boombox's headphone output jack would silence the device, leaving only the subwoofer to produce audio signal. Add a subwoofer to your boombox setup in less than five minutes.
