2 ohms or 4 ohms?

[CentralFC 10+ year member]

So my subwoofer (Alpine Type R 12") is dual voice coil 4 ohm. Now what I'm confused with is it's wiring down to 2 ohms (for 500 watts RMS). I wired down to "2 ohms", but is that per voice coil, making it 4 ohms, thus leaving me with only 300 watts RMS? If so, does that mean I'd have to wire it down to 1 ohm, making it 2 ohm total?

Basically what I'm asking is if the ohms are per voice coil, or total. Any help would be great! This would really make things clear.

You're confused, bro. Your sub can only be wired to 2 or 8 ohms. That's it...

1 ohm can be wired to 2 ohm or .5 ohm.

2 ohm can be wired to 4 ohm or 1 ohm

4 ohm can be wired to 8 ohm or 2 ohm

the wattage doesn't change that the sub can handle when it's wired on any ohm. so when you wire it up to 2ohms you can still run 500 to it. it just depends on the amp you're feeding it with. it's a total number cause you wire them both together.

There is a wiring chart on the fosgate site.That might make it easier to understand.
