SVC (Single Voice Coil)

DVC 2Ω

DVC 4Ω

1 Subwoofer Wiring Diagrams

DVC 2Ω → Parallel

1 OHM FINAL

AMP(+) → Both Sub(+) together
AMP(-) → Both Sub(-) together

✅

Use with 1-ohm stable amps

DVC 4Ω → Parallel

2 OHM FINAL

AMP(+) → Both Sub(+) together
AMP(-) → Both Sub(-) together

✅

Most common for mono amps

DVC 2Ω → Series

4 OHM FINAL

AMP(+) → Coil1(+)
Coil1(-) → Coil2(+)
Coil2(-) → AMP(-)

✅

Good for 4-ohm stable amps

DVC 4Ω → Series

8 OHM FINAL

AMP(+) → Coil1(+)
Coil1(-) → Coil2(+)
Coil2(-) → AMP(-)

✅

For high-voltage, low-current amps

2 Subwoofer Wiring Diagrams

2x DVC 4Ω → 1 Ohm Load

Wire each sub in parallel (2Ω each), then wire both subs in parallel to the amp.

1 OHM FINAL

2x DVC 2Ω → 2 Ohm Load

Wire each sub in series (4Ω each), then wire both subs in parallel to the amp.

2 OHM FINAL

2x DVC 4Ω → 4 Ohm Load

Wire each sub in series (8Ω each), then wire both subs in parallel to the amp.

4 OHM FINAL

2x DVC 2Ω → 4 Ohm Load

Wire each sub in series (4Ω each), then wire both subs in series to the amp.

4 OHM FINAL

🚨

Don’t wire below your amp’s limit!

If your amp is only stable to 2-ohms and you wire your subs to 1-ohm, you will trigger protect mode, overheat the amp, or fry the internal circuitry. Always check your amp’s birth sheet or manual before finalizing your wiring.

📋 Quick Reference: Common Wiring Configurations

1 SVC 4Ω: 4Ω load (single sub)

1 DVC 2Ω (parallel): 1Ω load

1 DVC 4Ω (parallel): 2Ω load

1 DVC 2Ω (series): 4Ω load

2 DVC 4Ω (parallel): 1Ω load

2 DVC 2Ω (series/parallel): 2Ω load

2 DVC 4Ω (series): 4Ω load

2 SVC 4Ω (parallel): 2Ω load

❓ Wiring Wizard FAQ

Does wiring change power handling?

No. Wiring only changes the load (impedance) the amp sees. Your subwoofer’s RMS rating stays the same regardless of how it’s wired.

What’s Series vs Parallel?

Series adds resistance (higher ohms). Parallel divides resistance (lower ohms). Series: + to -, + to -. Parallel: all + together, all – together.

Can I mix different subs?

Not recommended. Mixing impedances causes uneven power distribution and can damage your amp. Always use identical subs.

Why use DVC subs?

Dual Voice Coil subs give you flexibility to achieve different final impedances with the same sub, letting you match almost any amp.
