three Speaker ,4 ohm Single Voice Coil

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

Option 1 (parallel) = 1.34 ohm load

4-ohm SVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting three pieces in parallel (for each subs/speakers individually), as the image shows;make the equivalent impedance 1.33-ohm for an amplifier. Equivalent impedance: 1.33? (ohm) Recommended amplifier: Stableat 1-ohm mono amplifier

Option 2 (series) = 12 ohm load

4-ohm SVC subwoofer/speakers are rated at 4-ohm at each pair of terminals and connecting three pieces in series (for each subs/speakers individually), as the image shows;make the equivalent impedance 12-ohm for an amplifier. Equivalent impedance: 12? (ohm) Recommended amplifier: Stable at 4 or 2 or 1-ohm mono amplifier
