one alpine swr 12d4 with this amp at 2ohms be okay? what would be some issues? if any?
1509516
First off, what is the rms of that sub? This amp puts out 1200 watts rms at 2 ohms. Amplifiers work more efficiently when they are not wired to their lowest recommended impedance so i would feel comfortable saying that it would do its rated power. Issues: does your car have strong enough electrical to supply what this amp needs. At least upgrade the stock battery and use Good wire, OFC (oxygen free copper) 4 gauge at least, 0 gauge if you plan to run multiple amps. I would also suggest at least 12 gauge ofc speaker wire, i use 0 gauge ofc power wire, 8 gauge speaker wire, wired to 1 ohm, 2 batteries and a 4 channel amp as well. Knukoceptz wire and kinetik batteries. First off, what is the rms of that sub? This amp puts out 1200 watts rms at 2 ohms.

I'm no expert, and don't know what they mean by 4 ohm topology. Generally, the 4 ohm amp would be underpowered trying to drive 2 ohm speakers. Should be ok at low to moderate volume but high volume could overheat the amp. You should ask on a car stereo forum.

I would, but not that well cause this amp is only rated at 500 wats rms, and 2 12's at 400 a piece is more than it can handle. It would probably start to get warm or even hot.

Sure, that's the way i have it. Sounds great. Just check your amp power before, but normally it would work just fine.

I have 2 ALPINE SWR-12D4'S,THE AMP I'M USING IS A LIGHTNING AUDIO 1000.1md @ 1 ohm & they slam every time I turn the corner I be turning heads, the only problem I have is my lights dim pulling to much power!how many speakers do u have?

Higher ohms are always compatible. As long as you stay above 2 per channel or 4 bridged you'll be fine with this amp.

Yes im running 2 12in comp Rs at 1 ohm there's plenty of power.best amp ive had so far no problem gets a little hot at 1 ohm but doesn't overheat and go to emergency shutoff

It depends! At 1 ohm what's the output of the amp? If it's 1 ohm stable and pushing at least 750 watts then you good. Also depends on how many woofers. I would suggest only running 1 sub off it!

Yes for sure.. Wire your speaker to one ohm.. Hope your amp is stable at one ohm

I am not familiar with the specs on those speakers. But this amp is only 4 ohm stable. I run two SI18'S dvr subs wired for 4 ohms off of one channel, and run another Ixl 18 svs 4 ohm load on the other channel. Have no problems whatsoever. Try the12volt.com and see the different wiring options for your subs.

Yes it would run it safely and efficently, im running a alpine type r 10 with dual 4ohm voice coils wired to 2ohms on this amp, and it hits hard. mines running at 550 watts

As long as you are truly running 2ohms and the amp is pushing 300w RMS than you will be pushing it just fine. Not too hard, not to little. I run my single 10W3v3-2 by a 500/1 JL slash- which is a true 500 RMS and have had it for several years with no problems. In my opinion, don't run that sub any less than a true 300 RMS!

That amp would be perfectly fine for two of these subs wired at 2 ohms if yiu wire to 1ohm you may blow them though

Get the d4 not d2. 4 ohm can be ran parallel to get 1 ohm. The d2 can only be run at 2 ohm or .5 ohm if you have the right amp. And yes 1200 is okay once they are broken in.

I checked the specs on this amp and it is two ohm stable. No need to bridge. With just these 4 speakers and single amp, you should get 100x4 @ 2 ohm(RMS). Which is within the range of the speakers. The Peak power is 235x4 @4ohm, which may be slightly higher @ 2 ohm. This is just above the recommended power for the speakers, which should not pose a problem as long as you don't max out the gains and volume on the head unit.

I run that same amp with the 2ohm sub, it is perfect sounds awesome and they both should run forever set up properly.

I'm running mine on my stock OEM amp and haven't had any problems. I may not be the best person to answer this since I'm not putting a lot of power through them.
