How to wire 4 dual 2 ohm subs to 1 ohm

To wire 4 dual 2 ohm subs to 1 Ω: Each sub’s two coils in series: 4 Ω per sub. Subs in parallel.

Another way to the same load: Each sub’s two coils in parallel: 1 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.

The other final loads these subs can make: 0.25 Ω, 4 Ω, 16 Ω.

1 Ω: Each sub’s two coils in series: 4 Ω per sub. Subs in parallel.

1 Ω: Each sub’s two coils in parallel: 1 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.

Final load	How
0.25 Ω	Each sub’s two coils in parallel: 1 Ω per sub. Subs in parallel.
1 Ω	Each sub’s two coils in series: 4 Ω per sub. Subs in parallel.
1 Ω	Each sub’s two coils in parallel: 1 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.
4 Ω	Each sub’s two coils in series: 4 Ω per sub. 2 pairs in series, the two subs of each pair in parallel.
4 Ω	Each sub’s two coils in parallel: 1 Ω per sub. Subs in series.
16 Ω	Each sub’s two coils in series: 4 Ω per sub. Subs in series.

On each sub, jump coil A − to coil B +. A + and B − are now the sub’s terminals.

Every sub’s + to amp +, every sub’s − to amp −.

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.

To wire 4 dual 2 ohm subs to 1 Ω: Each sub’s two coils in series: 4 Ω per sub. Subs in parallel.

With balanced wiring: 0.25 Ω, 1 Ω, 4 Ω, 16 Ω.

Only if its manual says it is stable at 1 Ω or lower. Below that it runs hot, goes into protect or fails.
