What is the impedance on my SA-12 D2's?

[xander37 10+ year member]

I'm looking at the wiring wizard here Rockford Fosgate® - Woofer WiringWizard and I need to know the impedance. My first choice was 2x2 and I thought that was right but it didn't have a 1 ohm option. I've looked at the manual for my amp and in the installation instructions it says it can be wired down to 1 ohm bridged. Can I do this? Or do I not have the right impedance subs?

your woofers are dual 2 ohm.

and parallel wiring will give you a 1 ohm load....pos to pos neg to neg.

wouldn't that bring me down to half an ohm? according to this guy

it will. Unless I misunderstood something.

If its single sub you'll get a 1ohm load, if its 2 it'll be half ohm in parallel. With your subs you can wire to half ohm or 2ohm.

d2 stands for dual 2. so single sub you can wire to 1 or 4 ohm. 2 subs you get .5 or 2 ohms

**** well since my amp can't go lower than 1 ohm it looks like I'm going to have to wire both subs to 2 ohms using the wiring wizard.

Yeah, then wire each woofer to 4ohms, and parallel the two woofers at the amplifier or enclosure lugs to see the 2ohm final impedance.

What amp do you have and how is your electrical?
