How do I wire a dual coil subwoofer?
Wiring a dual coil subwoofer can seem complicated at first, but it becomes easier once you understand the basics of the wiring configurations. The two most common methods for wiring are series and parallel. In a series setup, you connect the positive terminal of the first coil to the negative terminal of the second coil, which results in a higher overall impedance. This configuration is useful if you’re trying to match a higher resistance rating for your amplifier.
On the other hand, a parallel wiring setup involves connecting both positive terminals together and both negative terminals together, effectively lowering the overall impedance. This method allows for more power to be delivered to the subwoofer, making it beneficial for systems with amplifiers that can handle low-impedance loads. Always double-check your amplifier’s specifications before deciding on the wiring configuration to ensure optimum performance.
What is the difference between series and parallel wiring?
The main difference between series and parallel wiring lies in how the voice coils are connected and the resulting impedance. In series wiring, the coils are connected end-to-end, which adds their impedances together. For instance, if you have two 4-ohm coils wired in series, the total impedance will be 8 ohms. This setup can be useful when your amplifier is rated to work best with higher resistance.
In contrast, parallel wiring connects the positive terminals together and the negative terminals together, effectively lowering the combined resistance. For example, if you connect two 4-ohm coils in parallel, the resulting impedance drops to 2 ohms. This configuration is advantageous for systems where more power needs to be pushed through the subwoofer without exceeding the amplifier’s capabilities.
Can I use a single voice coil amplifier with a dual coil subwoofer?
Yes, you can use a single voice coil amplifier with a dual coil subwoofer, but you need to pay careful attention to the wiring configuration and impedance.
