You could try the 2dvr is series which would give you 8......put that in parallel with the svc 4 ohm......that will give you 2 2/3 ohm which is probably safe for the amp.

Or just use one voice coil of the 4 ohm dvc and put it in parallel with the 4 ohm svc to get 2 ohms. No reason or advantage to using both vc in this case.
