Connecting your home stereo speakers to your computer's internal soundcard can expand your digital music listening experience. All that it takes is a way to amplify the speakers and the right cable. Once you know how to wire the system directly to your soundcard, you will be able to bypass the internal speakers on your laptop or the connected computer monitor speakers for good. With the right instruction, you can wire the speakers to your machine in less than five minutes.

  1. 1

    Connect the stereo speakers to the audio receiver with the speaker wire. Plug the red, or positive, end of the wire into the red connector on the receiver's main speaker-out jack, then the white, or negative, end of the wire into the black connector on the same output jack.

  2. 2

    Plug the RCA ends of the RCA-to-1/8" audio cable into the "CD" or "Aux" input jacks. The input jacks are commonly housed on the back of most receivers.

  3. 3

    Plug the 1/8" end of the same cable into your computer's "Line Out" jack. The "Line Out" jack on most computers is usually green and is on the back or side of the casing. Some laptops do not have colour-coded soundcard connections, but this is usually the jack to the right on most models. If you are uncertain as to which jack is the "Line Out" for your particular model, refer to your owner's manual for a detailed description of its internal soundcard.

  4. 4

    Press the "Source" button on your receiver until either "CD" or "Aux" appears as the input source on its screen. Select the same input source that you connected the RCA-to-1/8" inch audio cable to.

  5. 5

    Play a piece of music on your computer, such as an MP3 or WAV file, and listen as the audio plays through your stereo system.
