1 Ohm Sub Wiring Diagram

Hello and welcome to our comprehensive guide on the 1 ohm sub wiring diagram. In this article, we will provide you with detailed information and step-by-step instructions on how to properly wire a subwoofer at 1 ohm impedance. Whether you are a car audio enthusiast or just looking to upgrade your audio system, understanding the wiring diagram is crucial for optimal performance. So, let’s dive right in!

1. Understanding Impedance

Before we delve into the wiring diagram, it’s important to understand what impedance means in the context of subwoofers. Impedance refers to the resistance that a subwoofer presents to an electrical current. It is measured in ohms and plays a significant role in determining how much power your subwoofer can handle. Lower impedance, such as 1 ohm, allows for more power to be delivered to the subwoofer, resulting in louder and deeper bass.

2. Benefits of 1 Ohm Wiring

Wiring your subwoofer at 1 ohm offers several advantages. Firstly, it allows your amplifier to deliver its maximum power output to the subwoofer, resulting in louder and more impactful bass. Secondly, it ensures that the subwoofer operates efficiently and does not strain the amplifier. Additionally, wiring at 1 ohm provides greater flexibility when it comes to adding more subwoofers to your system in the future.

3. Step-by-Step Wiring Instructions

Now, let’s walk through the step-by-step process of wiring a subwoofer at 1 ohm impedance:

  1. Start by gathering all the necessary tools and materials, including a subwoofer, amplifier, speaker wire, and a wiring harness.
  2. Identify the positive and negative terminals on both the subwoofer and amplifier.
  3. Connect the positive terminal of the subwoofer to the positive terminal of the amplifier using a speaker wire.
  4. Connect the negative terminal of the subwoofer to the negative terminal of the amplifier using another speaker wire.
  5. Double-check all the connections to ensure they are secure and properly connected.
  6. Finally, connect the wiring harness to the amplifier and the power source to complete the wiring process.

4. Alternative Wiring Options

While wiring your subwoofer at 1 ohm provides numerous benefits, there are alternative wiring options available depending on your specific needs. One common alternative is wiring at 2 ohms, which still delivers significant power to the subwoofer while offering a slightly easier load on the amplifier. However, keep in mind that this may result in a slightly reduced bass output compared to 1 ohm wiring.

6. Frequently Asked Questions (FAQ)

Q: Can I wire multiple subwoofers at 1 ohm?

A: Yes, you can wire multiple subwoofers at 1 ohm by connecting them in parallel. This allows you to maximize the bass output while maintaining the 1 ohm impedance.

Q: What gauge wire should I use for 1 ohm subwoofer wiring?

A: It is recommended to use a high-quality speaker wire with a gauge suitable for the power output of your amplifier. Thicker wire, such as 12 or 10 gauge, is typically preferred for 1 ohm wiring to minimize power loss.

Q: Will wiring my subwoofer at 1 ohm void the warranty?

A: It is essential to check the warranty terms and conditions provided by the manufacturer of your subwoofer and amplifier. While wiring at 1 ohm is a common practice, it’s always best to confirm with the manufacturer to avoid any potential warranty issues.


Properly wiring your subwoofer at 1 ohm impedance is crucial for achieving optimal bass performance in your car audio system. By following the step-by-step instructions provided in this guide and understanding the benefits and alternatives, you can enhance your audio experience and enjoy powerful, deep bass. Remember to always double-check your connections and consult the manufacturer’s guidelines for your specific subwoofer and amplifier. Happy wiring!
