Each sub will be 2 ohms by paralleling the coils. Put a sub onto each channel for a 2 ohm stereo output.

What I would do, though, is series the coils to make each sub 8 ohms, then parallel the two subs together and bridge the channels with the 4 ohm load. That is a 2 ohm output, as well, and the result will be mono.

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

Since they are 4 ohm dvc you need to run a wire from the positive of one coil to the other, and the same with negative. Then just run a wire from one of the negative to the negative on the amp, and the same with positive
