A common car audio upgrade involves adding an amplifier to the vehicle to power new, high-performance car speakers. For the best possible performance, the amplifier and the speakers should be connected to each other with new speaker wire. This is easy to do in some speaker locations, and harder in others. One area of difficulty for installers is running speaker wire to the doors. Most cars have a rubber boot connecting the car body and the door that contains wiring. Routing the new car speaker wires through this rubber boot solves the issue.

  1. 1

    Straighten a wire coat hanger. Untwist the wire and work it so that you have a length of stiff wire that's about 18 inches long.

  2. 2

    Place the end of your speaker wire parallel to the wire, at the end of the wire, and tape it to the wire with electrical tape, wrapped several times around the wire and speaker wire.

  3. 3

    Carefully push the end of the wire with the speaker wire attached through the rubber boot. You can start at the door side or the car side, depending on which is easier to access.

  4. 4

    Push the wire through until the end appears at the opposite end of the boot. Untape the wire from the end of the coat hanger and grasp it firmly. Pull the coat hanger back out of the boot.

  5. 5

    Pull the remainder of the speaker wire through the rubber boot and proceed with your speaker wiring.
