How to Hook Up Harmon Computer Speakers to an HDTV

By James Clark

Harmon Kardon computer speakers can be quickly connected to an HDTV with a Y-adapter to convert the TV output jacks into a single jack that will work with the speaker system. The Harmon Kardon speakers are self-powered, so the HDTV will not face any power demands by adding additional sound. Since the computer speakers also come with a subwoofer, low-frequency bass response should be improved over the built-in speakers in the TV set.

Things You'll Need

  • Stereo cables
  • Y-adapter with two 1/4-inch jacks and a 3.5mm mini-plug jack

Step 1

Insert the white and red plugs on the stereo cables into the left an right audio output jacks on the back of the HDTV.

Step 2

Push the plugs on the other end into the two large jacks on the Y-adapter.

Step 3

Connect the 3.5mm plug on the end of the Harmon Kardon subwoofer cable to the small jack on the Y-adapter.

Step 4

Plug the cables from the left and right Harmon Kardon computer speakers into the matching jacks on the back of the subwoofer.

Step 5

Plug the subwoofer power cord into a wall outlet.

Tips & Warnings

  • Unplug the HDTV from electricity while hooking up the speakers.
