How to Connect External Speakers to an LCD TV

Updated February 21, 2017

Connecting a pair of external speakers to an LCD TV expands the sound in the room without moving in a lot of bulky stereo components or full-size speakers. Self-powered speakers are needed for the connection because the LCD TV's amplifier is only powerful enough to run the built-in speakers. You can hook up a pair of computer speakers quickly to achieve good sound in a small space by using an audio Y-adaptor, which is available at electronics stores.

Set up the speakers on each side of the LCD TV for stereo sound separation.

Plug the cable attached to the left speaker into the audio out jack on the side or back of the right speaker.

Plug the cable from the right speaker into the smallest of the three jacks on the Y-adaptor.

Connect the stereo cable from the two jacks on the Y-adaptor to the stereo output jacks on the back of the LCD set.

Plug in the electrical cord to the power jack on the speakers, usually the right speaker where the amp is located, and connect the other end to a wall outlet.
