four Speaker ,4 ohm Dual Voice Coil

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

Option 1 (parallel) = 0.5 ohm load

4-ohm DVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting fourpieces in parallel (for both cases- sub/speakers voice coil terminals and individual pieces), as the image shows;make the equivalent impedance 0.5-ohm for an amplifier. Equivalent impedance: 0.5? (ohm) Recommended amplifier: Stable at 0.5-ohm mono amplifier

 

Option 2 (series/parallel) = 2 ohm load

4-ohm DVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting four pieces in parallel (for each subs/speakers individually) & series (for each subs/speakers voice coil connectivity terminals), 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 3 (parallel/series) = 8 ohm load

4-ohm DVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting four pieces in series (for each subs/speakers individually) & parallel (for each subs/speakers voice coil connectivity terminals), 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
