How to Connect 2.1 Speakers to a TV

Updated February 21, 2017

A 2.1 speaker system consists of left and right stereo speakers connected to a powered subwoofer for bass. Commonly used for computer audio applications, the compact size of a 2.1 system also makes it a good choice for adding audio to a TV set in a small space where a rack of stereo components and floor speakers might be impractical. A 2.1 system also connects in a matter of seconds, so the entire speaker package can be disconnected and moved to another room, if desired.

Connect the plug on the end of each speaker cable to the corresponding left and right audio output jacks on the rear of the subwoofer. The speakers are labelled L and R on the back to aid in placement on each side of the TV.

Hook up the plug on the end of the subwoofer cable to the smallest of the three jacks on the Y-adaptor. The other two jacks are labelled L and R to distinguish the stereo channels that will connect to the TV.

Connect the white plug on one end of the stereo cable to the L jack on the Y-adaptor and insert the red plug into the R jack. Insert the plugs on the other end into the matching white and red audio output jacks on the rear panel of the TV. Be sure to connect to the TV jacks labelled "output."


Hook up the speakers and subwoofer to the TV with stereo cables before connecting the 2.1 system to a power outlet.
