How to wire 4 dual 1 ohm subs to 2 ohm

To wire 4 dual 1 ohm subs to 2 Ω: Each sub’s two coils in series: 2 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.
Another way to the same load: Each sub’s two coils in parallel: 0.5 Ω per sub. Subs in series.
The other final loads these subs can make: 0.13 Ω, 0.5 Ω, 8 Ω.
2 Ω: Each sub’s two coils in series: 2 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.
2 Ω: Each sub’s two coils in parallel: 0.5 Ω per sub. Subs in series.

Step by step

On each sub, jump coil A − to coil B +. A + and B − are now the sub’s terminals.
Wire the two subs of each pair in parallel (+ to +, − to −). Then amp + to pair 1 +, pair 1 − to pair 2 +, pair 2 − to amp −.

Reading the diagram

Each box is one voice coil. Wires that meet are joined; use proper terminals, not twisted wire and tape.
Left side of each coil box is its + terminal. 1A = sub 1, coil A.
Nominal loads: the real impedance rises in the box and with frequency. Only balanced layouts are shown, where every sub gets the same power.

Frequently asked questions

Can 4 dual 1 ohm subs be wired to 2 ohm?

To wire 4 dual 1 ohm subs to 2 Ω: Each sub’s two coils in series: 2 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.

What loads can 4 dual 1 ohm subs make?

With balanced wiring: 0.13 Ω, 0.5 Ω, 2 Ω, 8 Ω.

Will my amp handle 2 ohm?

Only if its manual says it is stable at 2 Ω or lower. Below that it runs hot, goes into protect or fails.
