How to wire 2 dual 2 ohm subs to 2 ohm

To wire 2 dual 2 ohm subs to 2 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. Subs in series.

The other final loads these subs can make: 0.5 Ω, 8 Ω.

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

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

Final load	How
0.5 Ω	Each sub’s two coils in parallel: 1 Ω per sub. Subs in parallel.
2 Ω	Each sub’s two coils in series: 4 Ω per sub. Subs in parallel.
2 Ω	Each sub’s two coils in parallel: 1 Ω per sub. Subs in series.
8 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 2 dual 2 ohm subs to 2 Ω: Each sub’s two coils in series: 4 Ω per sub. Subs in parallel.

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

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