Bridged Subwoofer Wiring Diagram – A Complete Guide

Subwoofers are essential components for delivering high quality sound in car audio systems. The bridged subwoofer wiring diagram is a popular way of wiring subwoofers as it delivers more power and enhances the sound quality. In this article, we will guide you through the process of bridged subwoofer wiring diagram and answer some frequently asked questions.

What is Bridged Subwoofer Wiring Diagram?

The bridged subwoofer wiring diagram connects two channels of an amplifier to a single voice coil subwoofer. This method effectively doubles the power of the amplifier and provides a higher output voltage to the subwoofer. The bridged subwoofer wiring diagram is an ideal configuration for those who want to achieve higher sound quality and more volume.

The bridged subwoofer wiring diagram utilizes the impedance of the subwoofer to produce a higher output voltage. It is important to note that not all amplifiers are capable of bridging. Therefore, it is important to check the amplifier manual to see if it is possible to bridge the amplifier.

How to Wire a Bridged Subwoofer?

The bridged subwoofer wiring diagram is not difficult to wire. Follow these steps to wire a bridged subwoofer:

  1. Disconnect the power supply to the amplifier before wiring.
  2. Connect the positive output of channel A to the positive terminal of the subwoofer.
  3. Connect the negative output of channel B to the negative terminal of the subwoofer.
  4. Connect the negative output of channel A to the positive output of channel B.
  5. Connect the positive terminal of channel A to the positive terminal of the subwoofer.
  6. Connect the negative terminal of channel B to the negative terminal of the subwoofer.
  7. Reconnect the power supply to the amplifier and test.

This process is based on a two-channel amplifier. If you have a four-channel amplifier, follow the same process but connect each channel to a separate subwoofer.

Benefits of Bridged Subwoofer Wiring Diagram

The bridged subwoofer wiring diagram offers several benefits that make it a popular choice for car audio enthusiasts. These benefits include:

  • Increased power output: Bridging two channels of an amplifier effectively doubles the power and provides a stronger signal to the subwoofer.
  • Better sound quality: The bridged subwoofer wiring diagram reduces distortion because it provides a cleaner signal to the subwoofer.
  • Enhanced bass: Bridging the amplifier channels ensures the subwoofer receives more power, resulting in stronger bass.
  • Flexibility: The bridged subwoofer wiring diagram is ideal when you want to add additional subwoofers to your car audio system. With a powerful amplifier, you can bridge channels to accommodate more subwoofers.

FAQs

What is the difference between bridged and unbridged subwoofer wiring?

The difference between bridged and unbridged subwoofer wiring is in how channels of the amplifier are used. In bridged subwoofer wiring, two channels of the amplifier are connected to a single voice coil subwoofer. This method effectively doubles the power of the amplifier and provides a higher output voltage to the subwoofer. In unbridged subwoofer wiring, each channel of the amplifier is connected to a separate voice coil subwoofer.

Is bridged subwoofer wiring diagram suitable for all types of amplifiers?

No, bridged subwoofer wiring diagram is not suitable for all types of amplifiers. It is important to check the amplifier manual to see if it is possible to bridge the amplifier. Some amplifiers may not be suitable for bridging due to their design or power limitations.

Can I bridge a two-channel amplifier to two subwoofers?

No, it is not recommended to bridge a two-channel amplifier to two subwoofers. Bridging two channels to two subwoofers can lead to damage to the amplifier and subwoofers. Each channel of the amplifier should be connected to a separate subwoofer.

What is the best subwoofer size for bridged subwoofer wiring diagram?

The best subwoofer size for bridged subwoofer wiring diagram depends on your personal preference and car audio system. However, 10-inch and 12-inch subwoofers are popular sizes for bridged subwoofer wiring diagram as they provide a good balance of sound quality and bass response.

What is the output power of a bridged amplifier?

The output power of a bridged amplifier depends on the power rating of the amplifier and the impedance of the subwoofer. For example, a 100-watt amplifier that is bridged to a 4-ohm subwoofer will provide an output power of 200 watts to the subwoofer.

Conclusion

The bridged subwoofer wiring diagram is an effective way of increasing the power and sound quality of your car audio system. It is not difficult to wire and provides several benefits, including enhanced bass, better sound quality, and flexibility. Make sure to check the amplifier manual before attempting to bridge the amplifier, and always disconnect the power supply before wiring. With the correct set-up, bridged subwoofer wiring diagram can create an extraordinary listening experience.
