If you are an audio enthusiast, you know that a subwoofer is a vital component of any sound system. It is the element that gives your music the depth and bass that makes it enjoyable to listen to. However, connecting your subwoofer can be quite challenging, especially if you do not have the necessary knowledge. In this article, we will guide you through the process of subwoofer wiring, specifically dual 2 ohm subwoofer wiring diagram.
What is a Dual 2 Ohm Subwoofer?
A dual 2 ohm subwoofer is a speaker that has two voice coils, each with a resistance of 2 ohms. This type of subwoofer is common in car audio installations and requires a specific wiring setup to function optimally. The dual voice coils allow for more flexibility in wiring options compared to a single voice coil subwoofer.
How to Wire a Dual 2 Ohm Subwoofer?
Wiring a dual 2 ohm subwoofer might seem daunting, but it is relatively straightforward. There are two ways to wire a dual 2 ohm subwoofer: series and parallel.
Series Wiring
In series wiring, you connect the two voice coils so that they act as one, doubling the impedance. To wire a dual 2 ohm subwoofer in series:
- Connect the positive terminal of one voice coil to the negative terminal of the other voice coil.
- Connect the remaining positive and negative terminals to the amplifier’s positive and negative terminals, respectively.
The resulting impedance will be 4 ohms. This wiring setup is ideal when you want to increase your subwoofer’s impedance to match your amplifier’s rating.
Parallel Wiring
In parallel wiring, you connect each voice coil to the amplifier’s positive and negative terminals separately. To wire a dual 2 ohm subwoofer in parallel:
- Connect the positive terminal of each voice coil to the amplifier’s positive terminal.
- Connect the negative terminal of each voice coil to the amplifier’s negative terminal.
The resulting impedance will be 1 ohm. This wiring setup is ideal when you want to decrease your subwoofer’s impedance to match your amplifier’s rating.

FAQs
Q. What is the difference between series and parallel wiring?
A. In series wiring, you connect the two voice coils so that they act as one, doubling the impedance. In parallel wiring, you connect each voice coil to the amplifier’s positive and negative terminals separately, halving the impedance.
Q. What is the advantage of a dual 2 ohm subwoofer?
A. A dual 2 ohm subwoofer allows for more flexibility in wiring options compared to a single voice coil subwoofer.
Q. Can I wire two dual 2 ohm subwoofers together?
A. Yes, you can wire two dual 2 ohm subwoofers together. You can wire them in series or parallel, depending on your desired impedance.
Q. What is the ideal impedance for my amplifier?
A. The ideal impedance for your amplifier depends on its rating. Check your amplifier’s manual or specifications to determine its ideal impedance range.
Q. Can I wire a dual 2 ohm subwoofer to a 1 ohm stable amplifier?
A. Yes, you can wire a dual 2 ohm subwoofer to a 1 ohm stable amplifier. Simply wire the subwoofer in parallel to achieve a 1 ohm impedance.
In conclusion, wiring a dual 2 ohm subwoofer might seem complicated, but it is not. With the right wiring diagram and some basic knowledge, you can easily connect your subwoofer to your amplifier and enjoy high-quality sound. Make sure to match your subwoofer’s impedance to your amplifier’s rating for optimal performance.
