How to wire a dual 1 ohm sub to 0.5 ohm
To wire a dual 1 ohm sub to 0.5 Ω: Each sub’s two coils in parallel: 0.5 Ω per sub. One sub to the amp.
The other final loads these subs can make: 2 Ω.
0.5 Ω: Each sub’s two coils in parallel: 0.5 Ω per sub. One sub to the amp.

Step by step
On each sub, join A + to B + and A − to B −.
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 a dual 1 ohm sub be wired to 0.5 ohm?
To wire a dual 1 ohm sub to 0.5 Ω: Each sub’s two coils in parallel: 0.5 Ω per sub. One sub to the amp.
What loads can a dual 1 ohm sub make?
With balanced wiring: 0.5 Ω, 2 Ω.
Will my amp handle 0.5 ohm?
Only if its manual says it is stable at 0.5 Ω or lower. Below that it runs hot, goes into protect or fails.
