How to wire 4 single 1 ohm subs to 1 ohm

To wire 4 single 1 ohm subs to 1 Ω: 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.

1 Ω: 2 pairs in series, the two subs of each pair in parallel.

Final load	How
0.25 Ω	Subs in parallel.
1 Ω	2 pairs in series, the two subs of each pair in parallel.
4 Ω	Subs in series.

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 −.

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 single 1 ohm subs to 1 Ω: 2 pairs in series, the two subs of each pair in parallel.

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

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