The Goal: Wiring to 1 Ohm The objective in wiring 2 dual 2 ohm subs to 1 ohm is to create a stable load that measures close to 1 ohm total. Then, you connect the negative terminal of the amplifier to the negative terminals of both subs.
Calculating the Correct Impedance for Dual 2 Ohm Subwoofers
To achieve the lower impedance needed, you must bridge the internal taps to wire the coils in parallel, dropping the sub's impedance to 1 ohm before you even begin wiring to the amplifier. 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.
Coil Configuration Options Before you even touch the wiring harness, you must decide how to configure the coils within each subwoofer. 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.

This design offers flexibility because you can choose to utilize only one coil or wire both coils to achieve different total impedances. 5 ohms, which is too low and potentially dangerous for most amplifiers.
