two Speaker , 4 ohm Single Voice Coil

Subwoofer Wiring Wizard, Two 4 ohm Single Voice Coil (SVC) Speakers

Option 1 (parallel) = 2 ohm load

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

 

Option 2 (series) = 8 ohm load

4-ohm SVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting two pieces in series (for individual pieces), as the image shows; make the equivalent impedance 8-ohm for an amplifier. Equivalent impedance: 8? (ohm) Recommended amplifier: Stable at 4 or 2 or 1-ohm mono amplifier
