Are you wondering how to wire a 2 ohm single voice coil subwoofer? Whether you’re installing a new subwoofer or replacing an old one, understanding how to wire it properly is essential for achieving the best sound quality. In this article, we will provide you with a comprehensive guide on how to wire a 2 ohm single voice coil subwoofer, including a wiring diagram, tables, and frequently asked questions.
Understanding Ohms and Voice Coils
Before we dive into the wiring diagram, let’s first understand what ohms and voice coils are. Ohms are a unit of electrical resistance, and subwoofers are typically rated by the impedance they produce, which is measured in ohms. Lower ohm ratings require more power to drive the subwoofer, but produce louder and clearer sound.
A voice coil is a coil of wire that is wrapped around a cylinder, typically made of aluminum, and situated inside the subwoofer. The voice coil produces the electromagnetic force necessary for the subwoofer to move back and forth, creating sound waves.
Wiring a 2 Ohm Single Voice Coil Subwoofer
To wire a 2 ohm single voice coil subwoofer, you will need a subwoofer wiring kit that includes a speaker wire, amplifier wiring kit, and RCA cables. Follow these steps:
- Disconnect the negative battery terminal of your vehicle.
- Connect the positive speaker wire from the subwoofer to the positive terminal of the amplifier.
- Connect the negative speaker wire from the subwoofer to the negative terminal of the amplifier.
- Connect the RCA cables from the amplifier to the RCA inputs on your head unit.
- Connect the power wire from the amplifier to the positive battery terminal of your vehicle.
- Connect the ground wire from the amplifier to a metal point on the vehicle’s chassis.
- Connect the remote turn-on wire from the amplifier to the remote turn-on wire on your head unit.
- Reconnect the negative battery terminal of your vehicle.
Once you have completed these steps, your subwoofer should be wired and ready to produce sound.

FAQ
What is the difference between a single voice coil and a dual voice coil subwoofer?
A single voice coil subwoofer has one coil of wire wrapped around the cylinder, whereas a dual voice coil subwoofer has two coils of wire wrapped around the cylinder. Dual voice coil subwoofers have more wiring options, but single voice coil subwoofers are generally easier to wire.
What is the difference between a 2 ohm and a 4 ohm subwoofer?
A 2 ohm subwoofer has less electrical resistance than a 4 ohm subwoofer, which means it requires more power to drive, but produces louder and clearer sound. A 4 ohm subwoofer is easier to drive, but produces less sound. The choice between a 2 ohm and a 4 ohm subwoofer depends on personal preferences and the specifications of your amplifier.
Do I need a subwoofer box?
A subwoofer box is not necessary, but it can enhance the sound quality of your subwoofer by providing an enclosed space for the speaker to operate in. The size and shape of the box can affect the sound quality, so it’s important to choose the right box for your subwoofer.
Can I wire multiple subwoofers together?
Yes, you can wire multiple subwoofers together, but this requires understanding how to wire them in parallel or series. Wiring them in parallel means connecting all the positive terminals together and all the negative terminals together. Wiring them in series means connecting the positive terminal of one subwoofer to the negative terminal of the other subwoofer.
Why is my subwoofer not producing sound?
There could be several reasons why your subwoofer is not producing sound, such as a faulty speaker wire, blown fuse, or incorrect wiring. Check all the connections and wires to ensure they are properly connected and functioning. If the problem persists, consult a professional.
In conclusion, wiring a 2 ohm single voice coil subwoofer requires understanding the basics of ohms and voice coils, as well as using the proper wiring kit and following the correct steps. By following the guidelines provided in this article, you can wire your subwoofer for optimal performance and sound quality.
