I'm wanting to run another of the same amp I already have (hifonics Zeus 2400.1) I have 2 sundown audio x12's right now the dual 2 ohm versions so I'm running at 1 ohm at the amp. My question is though if I had the second amp how would I keep it at 1ohm to keep the 2400 watts at each amp?

you should be able to run one amp per sub, wire each voice coil in parallel for a 1ohm load.

As long as you have means to give each amp the exact same signal and set each amp's gain the exact same. Otherwise, you are going to have inevitable cancellation of some frequencies.

will it be very noticeable?

that's how I have them wired now I believe, they have dual voice coils so if both are dual 2's sooo

2+2=4
2+2=4
4+4=1
Is that right?
But if I was to just run sub of of each amp I'd be at 4ohms per sub right? Which would significantly decrease my wattage which would be defeating the purpose of even adding the second amp lol.

Huh ?

Don't make it harder than it has to be. Click this link and scroll down and pick your configuration -

lol, what glh said.

2+2 = 1ohm sub #1
2+2 = 1ohm sub #2

If you have all 4 coils wired in parallel now you're running at 0.5ohms which the hifonics amp might handle but i'm sure it would prefer a 1ohm mono load much more.

Well after see what glh said I went back and double checked and I have a dvc 4 ohm versions. Idk where I got that I had the other. So now if I were to wire them up individual I'd have to run 2 ohms which again is defeating the purpose. So now that y'all have the correct info, how could I add another amp while retaining my one ohm load?

2 x 4 ohm DVC subs = 1 ohm when wired together and to a 1 ohm stable mono amp. So much for making it easy. In the link I posted, scroll down, pick 1 mono amp then pick 2 - 4 ohm DVC subs and see how they are wired together and wired to the amp. It is called series-parallel wiring. Dang. I'm drunk and I can figure it out. Don't take offense to that ! It is what it is. I can show you illustrations/diagrams better than I can tell you ! Now. What 2 subs do you have ? Model numbers. Are they in or going in a sealed enclosure or a ported enclosure ? If ported, what is the enclosure tuned at ? Whew ! We will continue from here.

OK. I have established your 2 X-12's will handle 1250 watts RMS each. They should be wired together and to the Zeus as a 1 ohm load. The Zeus supposedly does 2400 watts RMS into a 1 ohm load. I doubt it, but I reckon when you are looking for something to put out 2400 watts RMS, you can't be too picky. You need to be sure you know how to properly set the gain on that amp for 2400 watts @ 1 ohm using Ohm's Law, a DMM, and a testtone on CD, preferably recorded at -3db. Son, if you want to run big boy equipment like that, you need to learn how to set it up. I think you are probably a pretty good ol boy or I wouldn't be trying to help you so much. Now, if the enclosure you have is ported, you need to know the tuned frequency of it and use that frequency for the testtone. If it is a sealed enclosure, use 40 or 45 or 50 hz. What headunit do you have ? You need to find the maximum clean volume of it and play the testtone at that volume and then never turn it higher than that volume. Hopefully you can set the lowpass for the sub preouts on the headunit. If so, set it no higher than 80 hz and set the lowpass filter on the subamp to the highest number (so it's just a pass-thru). If your system is ported, hopefully you have a subsonic filter on your amp to set no more than 5 hz less than the tuned frequency. This will keep the subs from trying to play too low for the port, protecting them against over-excursion and beating themselves to death over time. Turn any bass boost on the headunit and amp off. Loudness off. EQ flat. Set the highpass for the door speakers somewhere 100 hz or above. Again, hopefully you can set the highpass on the headunit and if the door speakers are amped, set that amp's crossovers off or through or at the lowest highpass frequency (so it's just a pass-thru). To find your max clean volume of the headunit, after setting all that, turn your amp gains to the bare minimum, rput in a 1000 hz testtone (preferably recorded at -3db) and slowly turn up the volume knob 1 number at a time, listening for the testtone to go from a normal hum to a distorted buzz, then turn down 1 number. That is your maximum clean volume. Set your gains for both amps there and never turn the headunit up past that number and never use bass boost or loudness. If you alter the sound or EQ after that, you will need to reset the gains or risk clipping and burning up your voice coils. If you have a reputable audio shop around, set it all up per the above and have them set the amp gains with an oscilloscope, if you wish. Any questions ?

my head unit is a kenwood ddx319. all of that was setup when my local shop built and installed my new box witch is tuned to 28, ported box. I start clipping at around 28-29 depending on the song.and he also did it with an oscilloscope. Yes the way I have them wired now is down to 1ohm at the amp. But what I'm getting at is when I add the new amp do I just basically wire it like the original amp is while the original is still hooked up?

Yes, if it is now wired for 1 ohm with a mino amp and the new amp is 1 ohm stable mono.

I don't thnk you'll be able to accomplish exactly what you want to do... you'll be connecting one sub to each amp. Wiring the 2x 4ohm coils in parallel will give you a 2ohm load to each amp/sub combo.
I think you'll be surprised running each sub @ 2ohms tuned properly.

There may be a way to bi-amp the subs as they're wired now but that's a little beyond my expertise.

If he has a mono amp, he needs to only wire the 2 x 4 ohm DVC subs as a 1 ohm load to it, which is what he has already. Why would he want another amp ?

yes I have a mono now as will be the new one. Because sundown subs are heavily underrated, people have put 2500 watts on one x12 with no il effects. So my plan is now that you've hepled me figure out the wiring is to add another amp hifonics zues 2400.1d on top of what I already have now and keep the whole thing detuned to around 4000. And also adding another battery which would bring me to 3 total.

You are going to burn up 2 good subs. Where are you getting 4000 watts ?
