A high-quality sound system is one of the fundamental elements of enjoying movies and games on your computer. If your PC has a good-quality sound card, it is possible to connect anything from basic speakers to 7.1 stereo speakers to your computer system. With all the inputs and wires, however, hooking up your computer stereo system can be confusing.

Skill level:


  1. 1

    Locate the volume control unit. Note that the subwoofer is the volume control unit on some systems. All speakers will connect to the volume control unit.

  2. 2

    Connect each speaker to the volume control unit. Accomplish this by plugging in the RCA connector from each speaker to the appropriate input on the volume control unit. If you are installing 2.1 surround sound speakers or higher, these inputs should have a label such as "FL" or "FrontL" meaning that is the input for the front left speaker. On a standard two-channel (two speakers) system, look for a single RCA input on the volume control unit.

  3. 3

    Connect the subwoofer output to the volume control unit, unless it is the volume control unit. Note that you should skip this step if you are installing a two-speaker system.

  4. 4

    Connect the coloured computer speaker cables to the coloured input ports on the volume control unit. These speaker cables are usually green (front speakers), blue or black (rear speakers) and yellow or pink (subwoofer). Note that you will have only a green cable with a two-channel system.

  5. 5

    Connect the AC adaptor to the volume control unit. Set the speakers up around your computer, ensuring that the front speakers are in the front and that the rear speakers are behind your. Place the subwoofer on the floor pointing away from you.

  6. 6

    Connect the coloured speaker cables to the output ports on the back of your PC. Match up the colours. Note that some colours may vary slightly. Check your computer operator's manual for exact output colours.

  7. 7

    Plug the AC adaptor into a wall outlet and turn the speakers on. Start your computer and log into Windows.

  8. 8

    Configure your Windows sound by clicking on "Start" and selecting "Control Panel." Click on "Sound" and click on the "Playback" tab. Highlight "Speakers" and click on "Configure." Click on the "Audio channels" drop-down box and choose your speaker configuration. Click on the "Test" button and listen as Windows tests each speaker. Click "Next" and follow the prompts until finished. Click "OK."
