Coil Configuration Options Before you even touch the wiring harness, you must decide how to configure the coils within each subwoofer. 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.
Connecting Negative Terminals on Both Subwoofers
This design offers flexibility because you can choose to utilize only one coil or wire both coils to achieve different total impedances. If you wire the subs in series, the impedances add up, resulting in a 2 ohm load, which is not the goal here.
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. Subwoofer Coil State Subwooper Wiring Impedance per Sub Total System Impedance Internal Parallel (1 Ohm) External Parallel 1 Ohm 0.

5 ohms, which is too low and potentially dangerous for most amplifiers. This parallel connection between two 1 ohm loads results in a total impedance of 1 ohm.
