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. 5 ohms, which is too low and potentially dangerous for most amplifiers.
Understanding Amplifier Load with Dual 2 Ohm Subwoofers
Parallel wiring is the key; it divides the total resistance, effectively halving the load. Depending on whether you wire them in series or parallel, the total load presented to the amplifier changes.
Subwoofer Coil State Subwooper Wiring Impedance per Sub Total System Impedance Internal Parallel (1 Ohm) External Parallel 1 Ohm 0. Many enthusiasts purchase the powerful drivers expecting an easy plug-and-play experience, only to discover that impedance management is the real bottleneck.
Understanding Amplifier Load with 2 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. Often, these coils are already wired in series to present a 4 ohm load to the outside terminals.
