Subwoofer Wiring Guide With Calculated Impedance and Generated Diagrams

Choose your subwoofer count, voice coil type, and nominal impedance. The wizard calculates valid final loads, shows the exact series/parallel math, and generates a wiring diagram that keeps polarity and connection order clear.

Positive Is RedEvery positive conductor is drawn in red.

Negative Is BlackEvery negative conductor is drawn in black.

Load Is CalculatedFinal impedance is generated from standard circuit rules.

Step 1

Configuration

Set the wiring inputs, then choose from the valid final loads this calculator can produce.

Subwoofer quantity ?

Set the number of subs connected in this one wiring layout.

Per-coil impedance mode ?

Use a preset value or choose custom for uncommon ratings like 1.4 or 0.7 ohm.

Custom per-coil impedance (ohms)

Enter a custom nominal per-coil impedance.

Voice coil type ?

Single Voice Coil (SVC) Dual Voice Coil (DVC)

Available final impedance (ohms) ?

Choose a final load at or above the amplifier's minimum stable rating.

Wiring variant for selected impedance ?

Pick the layout that best matches your enclosure and wiring path.

Topology

Per-Sub Net Load

Nominal impedance is a rated value used for system design. Real measured impedance changes with frequency and enclosure behavior.

Step 2

Generated Wiring Diagram

Download the diagram or use the instructions below it to verify the wiring path.

Diagram legend: red = positive conductor, black = negative conductor. A line crossing another line does not mean a connection unless it lands on a terminal.

Select or enter impedance values to generate equation trace.

How To Use This Wizard (Beginner-Friendly)

Select your subwoofer quantity. This is the number of drivers connected to one amplifier output.
Select SVC or DVC based on your sub terminals. SVC has one plus/minus pair. DVC has two plus/minus pairs.
Enter the nominal per-coil impedance from the subwoofer specification sheet (for example: 2, 4, 1.4, or 0.7 ohm).
Choose a final impedance target from the generated list. These are calculated using standard series and parallel circuit rules.
Choose a wiring variant. Some loads can be reached more than one way.
Use the generated SVG diagram and step text to wire each coil first, then wire the whole sub network to the amplifier.

Electrical Rules Used

Series connection: R_total = R₁ + R₂ + ...
Parallel connection: 1 / R_total = 1 / R₁ + 1 / R₂ + ...
Equal loads in parallel: R_total = R / N

For DVC models, the tool calculates two stages in order: coil stage first (inside each sub), then network stage (between subs).

What This Tool Covers

1 through 4 subwoofers.
SVC and DVC subwoofer types.
Standard and non-standard per-coil impedance values.
Multiple valid topology variants for a shared final impedance result.
Equation trace for each generated result.

Install Verification Notes

Stay at or above the amplifier's minimum stable impedance rating.
Keep polarity consistent: amplifier positive to speaker positive, and amplifier negative to speaker negative.
For best predictability in a shared network, use matching subwoofer models and matching impedances.
Confirm the wiring path physically before applying high output power.
A DMM measures DC resistance, which is usually lower than nominal impedance.

Jargon Quick Reference

Nominal impedance: The rated impedance value used for design and amplifier matching.
Final load: The total nominal impedance the amplifier channel sees after all wiring is complete.
Topology: The electrical layout pattern (all series, all parallel, series-parallel, or parallel-series).
Per-sub net load: The impedance of one complete subwoofer after any DVC coil links are applied.
Polarity: Keeping positive-to-positive and negative-to-negative through every connection path.
