How to Wire a 2-Ohm DVC Subwoofer to 2 Ohms
When setting up your car audio system, it is crucial to match the impedance of your subwoofers with your amplifier. This ensures optimal performance and avoids potential damage to your equipment. In this article, we will explore how to wire a dual voice coil (DVC) subwoofer with a 2-ohm impedance to a total impedance of 2 ohms. We will also cover the implications of different configurations and what to do if you cannot achieve the desired impedance.
Understanding the Configuration
A DVC subwoofer typically has two coils, each rated at a certain impedance. In your case, both coils are 2 ohms. Proper configuration of these coils can affect the overall impedance of your system.
Wiring Options
Series Configuration
When you connect the two 2-ohm coils in series, the total impedance will be:
2 ohms 2 ohms 4 ohms
This configuration does not achieve the desired impedance of 2 ohms. In fact, this setup will result in a much higher impedance, which may not match your amplifier properly, potentially leading to suboptimal bass performance or damage to your subwoofer or amplifier.
Parallel Configuration
When you connect the two 2-ohm coils in parallel, the formula to calculate the total impedance is:
1 /(Rtotal) 1/R1 1/R2
For your scenario:
1 /(Rtotal) 1/2 1/2 1
Rtotal 1 ohm
This configuration results in a much lower impedance of 1 ohm, which is not the desired impedance of 2 ohms. Thus, this setup also does not achieve the intended impedance.
Achieving 2 Ohms
For DVC subs with 4-ohm coils, you can achieve a total impedance of 2 ohms by wiring the coils in parallel:
1 /(Rtotal) 1/4 1/4 1/2
Rtotal 2 ohms
However, if your subwoofer is 2-ohm instead, you cannot achieve a total impedance of 2 ohms without using a different configuration or subwoofer.
Conclusion
If your DVC subwoofer is rated at 2 ohms per coil, you cannot wire it to achieve a total of 2 ohms with standard configurations. If your subwoofer has 4-ohm coils, you can wire them in parallel to achieve the desired impedance of 2 ohms.
Remember that impedance matching is critical for your audio system. Incorrect wiring can lead to poor sound quality and potential damage to your components. Always refer to your subwoofer and amplifier manuals for specific impedance requirements and recommendations.
Frequently Asked Questions
Can I use two 2-ohm voice coils to get 2 ohms?
No, whether you wire the two 2-ohm coils in series or parallel, you will either achieve 4 ohms or 1 ohm, respectively. To achieve a total impedance of 2 ohms, you need either two subs with 2-ohm coils connected in series, or one sub with 4-ohm coils connected in parallel.
What is the best way to connect dual voice coil subwoofers?
The best way to connect dual voice coil subwoofers depends on the impedance requirements of your amplifier and the subwoofer. Generally, paralleling two 4-ohm coils will result in a 2-ohm impedance, which matches well with 2-ohm amplifiers. Always check your equipment specifications for optimal configuration.
