DIY: Hidden Subwoofer

A hidden subwoofer can help make a custom stereo system install look clean. It can also be a theft deterrent as would-be thieves may not be able to see it. The exact process for designing a hidden subwoofer system varies by vehicle. For example, hatchbacks will require a different design than SUVs. The size and scope of the installation will also play a role. For example, it is easier to hide one eight inch subwoofer over two 15 inch ones.

  1. 1

    Measure the boot of the car. Determine the best placement of the subwoofers in the boot. Depending on the size of the subs and the boot, the box should either be flush against the back seats or flat on the floor of the boot.

  2. 2

    Design the custom box. Make the box according to the measurements taken in step one and incorporate the subwoofer manufacturer's recommendations for box size. The box should be flush with the contours of the boot. Measure out all six sides. The box should look like the rest of the boot and not an independent piece.

  3. 3

    Cut out the six sides of box from plywood, fiberboard or particle board, using a jigsaw.

  4. 4

    Assemble the box. Use a drill and screws to put the sides of the box together.

  5. 5

    Cut out holes for the speakers. Use the dimensions given by the manufacturer to make sure the size of the hole is correct.

  6. 6

    Cut out six pieces of carpet that will go over the sides of the box. The carpet should match that of the car's boot.

  7. 7

    Liberally apply carpenter's glue to the back side of the carpet and adhere it to the box. Wait for the glue to dry.

  8. 8

    Cut out the carpet from the speaker holes.

  9. 9

    Drill a small hole in the back of the box for the speaker wires.

  10. 10

    Fish the speaker wires through the hole to the subwoofers.

  11. 11

    Insert the subwoofers into the holes. Fasten them in with screws.

  12. 12

    Drape a mesh speaker cover screen over the speakers. Pull the mesh screen tight and glue it to the edges of the top of the box.

  13. 13

    Insert the box into the car. Connect it to an amplifier. Test the system.
