Understanding the Dual 2 Ohm Subwoofer A dual 2 ohm subwoofer is not a single voice coil; it is two separate voice coils wired together internally, each measuring 2 ohms. When you wire 2 dual 2 ohm subs to 1 ohm, you are attempting to transform a specific load into a single, lower impedance path that your amplifier can handle with confidence.
Calculating the Right Impedance for Your Dual 2 Ohm Subwoofers
Coil Configuration Options Before you even touch the wiring harness, you must decide how to configure the coils within each subwoofer. This design offers flexibility because you can choose to utilize only one coil or wire both coils to achieve different total impedances.
You have two primary options for a single dual 2 ohm sub: leave the coils in their default wired state or reconfigure them. This process requires a precise understanding of series and parallel configurations, as getting it wrong can result in overheating, poor sound quality, or even damage to your equipment.
