Can this sub be set up at 2 and 4 ohms or just the 4 that's stated in the specs section? Is there an option as to how it's set up to the amp?

Only 4 Ohms. You'd need the dual voice coil version: Infinity Reference 1262w 12-Inch 1200-Watt High-Performance Subwoofer (Dual Voice Coil)

No it can't..there is a dual version of this speaker at 4 ohms...it can be dropped to 1ohm or 2ohms but the single voice coil cannot support 1ohm load

The manual specifies 6 ohm or higher. Mine are 8 ohm and work well with this amplifier. I don't know how well 4 ohm speakers would work.

Yes this amp is capable of running a 4ohm bridged load. But to be honest with the low power rating on your subs it could be overkill to use the amp in bridge mode. It's pretty stout just running at 4 ohms a side. You could do high pass and low pass with the built in crossover and runs your tops ans subs on one amp. I use this for my bass rig and run a 4ohm load per side. It screams....

From what I've read, that 4 ohm sub wants 150 watts RMS. That Alpine puts out 300 watts RMS at 4 ohms. You might save some money by looking for a bit smaller amp. But, if you don't overdrive the sub, that amp will work. It is nice clean power.

Well the impendance is very important to have correctly matched between the sub and amp. Since your amp is for 2 ohms, you need a 2 ohm sub. Or get a 4 ohm amp to be comparable with this sub

not too sure i have it running at 1ohm and it's great, the amp pushed my Diamond 12" 400watt sub great, clean sound too, getting the Alpine SWR-12D2 12 next week I'll let you know well it pushes that. I have my doubts but only time will tell, I can tell you that's it's not 3000 watts tho, but from experience it's enough for a single 12" 400 watt sub.

you can wire the sub as low as 1 ohm and the speakers to 2 ohm i believe on this amp. so yes you can do 2ohm for the sub "which would be a dual 4 ohm or dual 1 ohm dvc" and do your front stage at 4 ohms.

i have 2 of these and use in a tri-amp situation, mid and upper end only (took out tweeters and mids once JBL too) i would as i did go up a notch and go with the 4000 model for low end and yes 2 to 8 ohms possible

I wouldnt reccommend it. Follow the instruction manual on how to set it up. I believe this amp is 2 ohm stable.

yes. since it is a dual 4 ohm sub, it should be wired down to a 2 ohm load. and the amp does 500 on a 2 ohm load. it will be best to set gains with a multimeter.

I wouldn't set it up like that...I would definitely get 1 amp to run the speakers, and 1 to run the sub. I purchased a 1000w amp for the subs, and this amp for the 4 speakers. Works great.JL W6 12V24x Infinity Kappa Perfect 6 1/2

This is a dual coil sub so I'm assuming it is 2 ohms if you run the two coils in parallel and 8 ohms each side. This doesn't quite work out, you're right, as it should be two 4 ohm coils (which is how I see it described on sites that sell it) that in parallel is 2 ohms or in series is 8 ohms. I built my own box to the sealed box specs (remarkably small) and am driving it in stereo (though my head unit has a dedicated sub setting for outputs which may sum to mono on its own) with a 1000watt stereo amp and I assumed it was 4ohm per side. It sounds amazing in my little car, as a matter of a fact it took me forever to get the sub balanced with the rest of the system because it is amazingly efficient so I kept turning down the sub out as well as the amp trim and finally settled on running it with a 150hz cutoff instead of 75hz. Hope this helps.

the amp is at 4 ohm load, 2ndly are you asking about the implications of series or parallel hookup, hook it up to stay at the 4 ohms,= series. read a bit on the net about series & parallel. try them one at a time, noting amp temp,! aka does the fan come on? mine never did, so if yours does your pulling serious juice & sensitivity how much pre-amp line voltage required. are these subs or full range & are they in stock cabinets?

Well I have it pushing four 6.5 component speakers which is four tweeters and four mid range woofers and two 6x9s and it still seems like it has power to spare. I wired the back two doors with the 6x9s making the ohm rating 2. All of my speakers have 4 ohm ratings. That's the important part. This amp can be wired down to two ohms. Basically if you put two 4 ohm speakers on one channel it becomes 2 ohms. I would say you wont have a problem with this thing. I would say wire the 3.5 and tweeters with your front 2 doors and wire the rear doors with the 6x9s. That is basically my setup minus the 3.5

Oh yeah definately its two ohm stable but if your sub is only 300 watts it may just be to powerful and blow your sub this amp is serious

Are the subs wired correctly for 4ohms or 2 ohms. If so your gains need to be adjusted properly and any boosts from your deck turned off

This amplifier is not stable at 2 ohms. it is limited to 4 ohm loads or higher.
