I would like to know the best option for wiring my subs. My mono alpine amp is 350 watts at 2ohms, and 200 watts at 4ohms. I have two subs, one is a Rockford Fosgate fast&furious dual voice coil 4ohm sub, the other is a kicker single voice coil 4ohm sub. Is there a way to wire this to get down to 2 ohms to get the full power from the sub? I'd like to not ditch the 2nd sub as I have a dual enclosure and it will be in there if its used or not. I've been trying to figure this out and just can't. Any help would be greatly appreciated.
No way to get a 2 ohm load without not using one voice coil, which wastes power dragging around extra undriven weight.
I'd suggest wiring the Rockford Fosgate fast&furious dual voice coil 4ohm in series, then parallel it with the kicker single voice coil 4ohm sub.
The difference between 350 watts at 2ohms, and 200 watts at 4ohms is less than 3 dB, doubling cone area adds 3 dB, assuming the speakers have similar phase response.
Compare it to qguy's suggestion and see which produces more actual SPL, speakers have far different impedance at different frequencies, hard to say what will actually work best with your amp without testing.
That gives your amp a 6Ω load, The amp will be grateful for it. 🙂 This is how I would do it too.

So I mistakenly gave the average value but it seems that even this 2.6666...7Ω load can be handled by the amp, give it a try.
Yes. (In the case amp+low impedance doesn't work) The other way, (6Ω) is to parallel the 2 voice coils (2Ω) in one sub and series with second woofer (4Ω).
In addition; the best woofer or the one that can handle the most power, could be wired so it gets the most power.
If the DVC woofer can handle more power than put those DVC's in parallel and the drivers in series.
If the SVC woofer handles more power, put the DVC's in series and the drivers in parallel.

Same to you, I didn't notice my mistake about the average vs parallel mix-up. So we all learn, that's why we are here.
