Connecting external stereo speakers
You can take advantage of your computer’s stereo sound output by attaching
externally powered (amplified) speakers.

You need a cable with a stereo miniplug at one end to connect one or both
speakers to the computer.
Some speakers require a dual-plug adapter. Others, like those shown in the

speaker wires. See the documentation that came with your speakers for
more information.
