Powered computer speakers can add the all-important dimension of sound to your computing experience. With speakers hooked up, you'll get more enjoyment out of games and videos, and you'll be able to listen to sound from Internet radio, music files and CDs. Dell computers are built with audio outputs on the back panel that make it easy to hook up speakers.
Place one speaker on each side of your computer monitor. The two speakers will be connected to each other with a wire--route the wire behind your monitor so that it's out of the way.
Plug the audio cable of the speakers into the audio output of the computer. The speakers' audio cable terminates in a male 3.5mm stereo plug--it's identical to the type of plug you'll see on a pair of headphones. The computer's output is a 3.5mm female plug, color-coded with a green surround.
Plug the power cable of the speakers into a wall outlet or convenient power strip and turn the speakers on. The power switch is usually located on the front of the right speaker and is often integrated into the volume control.
