I have four subs, all with dual voice coils, and i was wondering if there is any way to hook them all up to have a total impedance of 4Ω. I played with the calculator for a bit but can't get it to 4Ω.

What ohm are the subs cause to get what you want you will need 2 ohm versions and wire like this:

eahc voice coil is 4 ohm, so each sub can be 8 or 2 ohm

(4) 4ohm dvcsubs cannot be wired into a 4 ohm load. The closest you can come is 2 ohms https://www.audiobahninc.com/tech/wiring/Series_Parallel_dual_4_ohm.pdf If you want to wire 4 subs into a 4 ohm load they would have to be 2 ohm dvc's like tdsteele said.
