two Speaker , 4 ohm Dual Voice Coil

Subwoofer Wiring Wizard, Two 4 ohm Dual Voice Coil (DVC) Speakers

Option 1 (parallel/parallel) = 1 ohm load

4-ohm DVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting two pieces in parallel (for both cases- sub/speakers voice coil terminals and individual pieces), as the image shows; make the equivalent impedance 1-ohm for an amplifier. Equivalent impedance: 1? (ohm) Recommended amplifier: Stable at 1-ohm mono amplifier

 

Option 2 (series/parallel) = 4 ohm load

4-ohm DVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting two pieces in parallel (at individual subs/speakers pieces) & series (at individual sub/speakers voice coil connectivity terminals), as the image shows; make the equivalent impedance 4-ohm for an amplifier. Equivalent impedance: 4? (ohm) Recommended amplifier: Stable at 4 or 2 or 1-ohm mono amplifier
