When installing a car audio system, you can use one or more subwoofers with the amplifier. If you want to use a single subwoofer with the amplifier, you can bridge the connection to get more sound. Bridging a subwoofer with a Pioneer car audio system is the process of sending more power to the subwoofer from a single amplifier. You can do this by properly wiring the subwoofer to the Pioneer amplifier.

Instructions

  1. 1

    Locate the speaker connections or terminals on the back of the Pioneer amplifier. If you have a two-channel amplifier, there are four terminals. Each channel has a positive and negative terminal.

  2. 2

    Cut 1/2 inch from both ends of a speaker wire with wire cutter. Connect one end of a speaker wire to the positive terminal, for Channel 1, on the amplifier, by pressing the tab on the positive terminal and then inserting the speaker wire into the opening.

  3. 3

    Connect the other end of the speaker wire to the positive terminal on the subwoofer. Press the tab on the positive terminal and then insert the speaker wire into the opening.

  4. 4

    Cut 1/2 inch from both ends of a second speaker wire with the wire cutter. Connect one end the speaker wire to the negative terminal, for Channel 2, on the amplifier. Connect the other end of the speaker wire to the negative terminal on the subwoofer.

  5. 5

    Turn on the car's ignition. Power on the car stereo and turn on the amplifier.

  6. 6

    Turn on the radio or play a CD to determine if the bridged subwoofer is working with the Pioneer amplifier. If you can hear sound from the subwoofer, it is working correctly.

  7. 7

    Repeat this process to bridge a second subwoofer with another amplifier.

Tips and warnings

  • A four-channel amplifier must be used to bridge two subwoofers to the same amplifier.
  • If you connect the speaker wire to the wrong terminal on the amplifier, no sound will come from the subwoofer.
