DVC wiring options

Coils in series, subs parallel is better than coils parallel, subs in series.

I prefer this wiring, then bridged across the two channels...rather than subs at 2 ohms each onto the respective channels.

Note: this is a preference call, as you will undoubtedly hear no difference whatsoever using any configuration which puts a 2 ohm load onto each channel.  There is also no inherent danger in using any of the above-mentioned wiring scenarios.
