6ohm speak, stable for 1, 2 or 4ohm, stable amp.
I hope this is me.

Option 1 (parallel) = 3 ohm load
Voice coils wired in parallel
Recommended Amplifier: Stable at 2 or 1 ohm mono

Option 2 (series) = 12 ohm load
Voice coils wired in series
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

This would be correct, also doing this if anyone else wants to know

1 DVC driver with Voice Coils in Series
Connecting the two voice coils of the driver in series (+ to -) will result in the following impedances:
Dual-6 Ohm Subwoofer: 12 Ohms
Dual-4 Ohm Subwoofer: 8 Ohms
Dual-2 Ohm Subwoofer: 4 Ohms

What was the question?

-------------
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
