You could get another DVC sub and then connect them in the following set up:
Run the 2 DVC's in both parallel and series. Since you are running 2 DVC, you should have 4 coils. If you wire it up correctly then you could put 2 coils in series making 8 ohms then wiring the other 2 coils in series making another 8 ohms. Then wiring these series connections would then put them into a 4 ohm setup.
I know this would work (in theory) but I am not quite sure the affect on the subs. If someone has objections and y this would work let me know. I might need to clarify myself a little more on this as well.
