How to Install a PC Subwoofer

Boost your low end by adding a subwoofer to your PC speaker configuration. Most new speaker sets in the mid-priced range already come with a subwoofer. Installing the subwoofer is part of the process of installing the speakers

Things You'll Need:

  • Computer
  • Speaker set with subwoofer


  • Unpack your speakers and subwoofer
  • Position the speakers as close to ear level as possible and the subwoofer on or near the floor. Make sure you identify the left and right speakers
  • Shut down your computer
  • Use the supplied cables to connect your speakers and subwoofer to each other. The configuration of your cables will be different depending on the set you bought-some speakers are hardwired to each other, some aren't
  • Connect your speaker unit to the sound card on your computer. Usually all you need to do is match up the color of the jack on the speaker cable to the color of the input on the sound card
  • Start your computer
  • Plug your speakers into a power source then turn the speakers on. Test the speakers

Tips & Warnings

  • If the subwoofer has the speaker controls on the front make sure to place this somewhere within easy reach
  • It's usually easiest to position the speakers and subwoofer first, and then drop the cables down the back of the desk or whatever they are sitting on. Depending on what type of computer desk you have and how long the speaker cables are, you may find it easier to connect them up first then position them afterwards

How to Install Subwoofers? 

Most automobile manufacturers do not consider subwoofers standard car stereo equipment. So if you want to beef up your bass, you will need to mount them yourself. Installing subwoofers is a tricky proposition but these steps can help you do the job yourself


  • Study the directions for installing the subwoofer and make sure you have the tools and mechanical expertise to undertake the project
  • Gather and assemble everything you will need to install your subwoofers, then detach your car's negative battery terminal
  • Fasten a ring terminal to the end of the power cable and attach it to the battery's positive terminal. Locate a spot nearby for the fuse holder and join it to the battery wire. Attach the end of the remaining wire to the other side of the fuse holder. The fuse should not be in the holder
  • Locate a spot where the wire can be brought through the firewall and inside the car. Ideally, the opening should go to one of the foot wells
  • Push and pull the wire through the opening and below the flooring until it reaches the subwoofer on the door frame or under the carpet. Extend it to the amplifier and verify the distance. Play it safe by tacking on several more feet. Cut the wire and hook up the amplifier
  • Find some bare metal or a sturdy bolt that runs inside the car several feet from the amplifier. When connecting to bare metal crease a ring terminal to the ground cable and attach it to the body with a thread cutting screw. If making an existing bolt connection, place a ring terminal on the body bolt. Now you are ready to join the ground to the amplifier
  • Follow the manual instructions on running remote and signal wires. Attach them to the amplifier and verify all your links
  • Test your amplifier and subwoofers and select your settings. Hook the negative battery terminal back up. With the fuse holder empty, activate your car's accessory power ignition to verify that everything works and none of the fuses are bad
  • Turn off the ignition to accessory power and place the fuse into the holder, connecting the amplifier. Verify the settings on your subwoofer. Activate the accessory power and switch on the radio. The sound of a bass line indicates a successful subwoofer installation

Tips & Warnings:

  • Mount your amplifier in a level, open area that is conducive to cooling
  • Do not affix the amp directly to your car's chassis.Rusty metal can be cleaned by sanding and then rubbing clean
  • Installing the fuse should be the final step.Ready-made amplifier kits come with everything you need to install your subwoofers

  • 1 x Subwoofer Speaker
