Place speakers in the walls of your home to save space when installing a surround sound or home theatre system.

  1. 1

    Locate the studs in the wall by using the stud finder. Install speakers in between wall studs. Mark the location of the studs with the pencil or painter's tape.

  2. 2

    Place the face of the speaker on the wall and trace around it with the pencil or use a template if one was included with the speakers. This process will put an outline of the speaker on the wall.

  3. 3

    Cut around the outline on the wall with the drywall saw. Take out the piece of drywall and set it aside.

  4. 4

    Open a package of 3-inch roll insulation and measure a piece that is 2 to 3 feet long with the tape measure. Cut the insulation with the utility knife.

  5. 5

    Insert the piece of insulation into the hole in the wall that was cut for the speaker. Connect the speaker wire to the speaker and mount the speaker in the wall.

  6. 6

    Repeat this process for additional speakers you want to mount in a wall.

Tips and warnings

  • Use the same amount of insulation for each speaker that is installed or mounted in a wall.
  • Wear gloves when cutting and inserting the insulation into the wall to prevent itching.
