Hooking up Hi-Fi speakers to a PC requires either a pair of speakers with built-in amplification, or an amp connected to the computer and high fidelity speakers. A computer does not contain an amplifier powerful enough to drive external speakers, so an external power source is necessary. When using an amp with full-size speakers, a Y-adaptor will be needed to connect the audio cables to the PC.

Skill level:

Things you need

  • Hi-Fi speakers and amplifier
  • or Self-powered speakers
  • Speaker wire
  • Audio cables
  • Y-adaptor

  1. 1

    Connect a pair of speakers to the amplifier with speaker wire, using the red wire for the right-channel connection and the other wire for the left audio channel.

  2. 2

    Insert the plugs on one end of a standard set of audio cables to a free set of audio jacks on the back of the amp, for example the Aux or Auxiliary jacks. The red plug connects to the right channel and the white plug connects to the left.

  3. 3

    Plug the other ends of the cables into a Y adaptor equipped with a 3.5mm mini-plug on the other end. Y adaptors are available at electronics stores.

  4. 4

    Insert the mini-plug on the Y adaptor into the computer's soundcard jack, or use the headphones jack on a laptop.

  5. 5

    Plug the amplifier into an electrical socket and turn on the component to power the external speakers.

  6. 6

    Connect self-powered speakers to the PC by inserting the mini-plug from the right-hand speaker into the computer's soundcard or headphones jack, then connect the mini-plug from the left speaker to the Audio OUT jack on the back of the right speaker. Plug the DC power cord into the right-channel speaker and connect the other end to a wall outlet.

Tips and warnings

  • An amplifier with a 5.1 Surround Sound speaker package enables the user to enjoy multichannel sound from the PC.
  • Do not plug in the equipment to the electricity until the audio connections are complete.
