Running your Deaf Bonce Atom 12.5k amplifier at 0.5 ohms with four Soundqubed HDX4 18 subs (each rated at 2k RMS) can be risky. Here are some points to consider:
1. Power Ratings: The amplifier's 0.5 ohm output will deliver significantly more than the 2k RMS rating of the subs, potentially damaging them if not managed properly.
2. Impedance Matching: Make sure that the subs' combined impedance allows you to run the load comfortably at 0.5 ohms. If configured in a series/parallel setup, ensure the wiring is done correctly.
3. Cooling: High power demands at lower impedances can lead to overheating. Ensure adequate ventilation and thermal management for your amp.
4. Clipping: Avoid pushing the amp into clipping, as this could severely damage your subs.
5. Testing: If you decide to proceed, start with a lower gain setting and gradually increase while monitoring the system for signs of distress.
It's advisable to consult with an audio professional or the manufacturer for specific recommendations based on your setup.
No, you should not try to run that amp on a 0.5-ohm wired load; the amplifier is not rated for 0.5 ohm operation, and you will void the warranty if, make that when, it blows.
Secondly, you have only two options for wiring these subs to that amp, .5 or 2 ohms, so 2 ohms it would have to be.
I am not aware that the Soundqubed HDX4 series comes in an 18", so I'll assume you meant 15".
They are 2000-watt RMS woofers, so the optimum amplification is somewhere in the 12k range, which you won't get at two ohms - tough break.
The amp is rated for 6950 at 2 ohms, so either get an amp that puts out 12k at 2 ohms or replace the subs with four dual 2 ohm woofers and wire them to 1 ohm.
So, how are you supporting that amp, electrically?
Additinally, the difference in output between roughly 7k watts and 12k is not very sub-stantial.
In a car, that 5000-watt difference (6950 to 12.5k) is likely to produce only about a 1.5 to 2db difference in output.
Are you going to be competing?

Yes the soundqubed hdx4 does come in an 18 yes I will be competing with this build. Talk to the builder he is suggesting running another deaf bonce 12.5k. And have 1 par on each sub at 2ohm final load
Cool, I didn't look very hard, might have been the site I went to.
Not that it's all that important, but man, gonna be a BIG box!
So, a set of dual 1-ohm drivers gives you 2 options per set.
1 ohm:
Or 4ohm:
So, you can power each set of sub drivers with one each of the 12K Atom amps (Atom amp, wasn't that an 80's pop singer?) at either 1 or 4, but not 2 ohms - which kind of leaves you in a bit of a pickle...
Each wired set will have a 4000 watt RMS thermal limit, so, as stated prior, you're going to want around 4k plus around 50%, that's around 6k per set.
The Atom 12K (at 14.4V at 4 ohms) puts out 3870 watts, underpowered and a waste of money.
At 1 ohm, it puts out 12k, WAYYYYY too much power, and again, a waste of money since you're talking about getting two ($2200.00).
If you're game to run two amplifiers, then consider a pair of the Atom 5.5k amps instead; same money as a single 12k but at 1 ohm, they put out around 5500 watts each, which is aligned for what your four, 18", dual 1-ohm drivers need.
AND, if you're running a lithium bank to support the amplifiers, you might want to consider something that gives you 15-16v, which will bump the two 5.5K amps to around 6K (@15v) and up to 6790 watts (@16v) each, a little overkill, but definitely a good overkill.
Not sure what category you'll be competing in, not proficient with information on how all that works, but I do know that each category has specifics as to what, when, and how you can use spefcific equeipment and electrical, which if your installer/builder is knowledgeable, he will know if this applies or is acceptable within the parameters of the catagory your wanting to compete in.
Another option would be to change the amplifier brand and go with something like PowerUS (a real modern-day cheater amplifier).
This model, with all the subs wired to that original 2-ohm load, puts out roughly 12000 watts @14.4 volts, and up to 15673 watts at 16Vs!

The problem is I already bought the 12.5k i think for now until I switch subs out in a year or 2 going to run both amps at 2ohms my lithium bank is going to be the xmax90 from xs batteries and doing 2 400 amp altenators with big 3 upgrade of course and I'm going to have 8 runs of 2/0 ofc. It's going in 2004 yukon denali. My builf guy who has his shop wants me to switch to the b2 audio rampage 18's later then I can run both amps at 1ohm but will add another xmax90 and 1 more 400 amp altenatoreCool, I didn't look very hard, might have been the site I went to.

Yeah, I hear ya, been there,done that!
Just a reminder: you don't have the option to run your sets of subs at 2 ohms; it's 1 or 4, no matter how you mix it up - on all four, it's .5 or 2.
You might as well run all 4 of the drivers at 2 ohms becuase you can't run it .5) instead of getting another amp; wait until you get dual 2 ohm subs that you can wire to a 1 ohm load.
The 12K you have already, ouputs close to 7000 watts at 2 ohms, dual 12Ks at 4 ohms each (the only practical option for the current subs) will net you aprixmatley 7700 watts (3870 ea), you'll never here the difference between 7700 watts and 7000 watts, no difference at all.
