How to Connect a Subwoofer to a Laptop

A subwoofer can improve the audio of your laptop.

Subwoofers reproduce the low frequencies of music and audio tracks, adding bass and impact to what you're listening to. The audio performance of a laptop computer can be greatly augmented by connecting a subwoofer to it. Although it's not a difficult task, you will need a few adapter cables to make the connections.

Step 1

Plug the mini-jack end of the mini-jack-to-dual-female RCA adapter into the headphones output of the laptop.

Step 2

Plug the male plugs of the dual-male-RCA-to-single-female-RCA adapter into the female jacks of the first cable.

Step 3

Plug the end of your subwoofer cable into the single-female RCA adapter. Plug the other end of the subwoofer cable into the subwoofer's input jack.

Step 4

Set the subwoofer's low-pass filter knob to 100 Hz. Plug the subwoofer into a wall outlet or power strip and turn the power on.

Step 5

Set your laptop's audio controls to allow the speakers and headphone jack to operate simultaneously.
