If your TV has an analog audio output (either stereo mini plug of 2 RCA jacks) then you just need the correct cable. If your TV only has a digital audio output (usually optical) then you will need a digital to analog converter like this: http/www.parts-express.com/digital-to-analog-converter-%2851-compatible%29--180-999
