To have 2x 2 ohm subs wired up, they either need to be wired in series or in parallel. In series, they will total as a 4 ohm load to the amp (or 5 ohms if 2.5 each) and in parallel, they will be 1 ohm (may be closer 1.25 ohms I think).

If this is a mono block (single channel) amp, I can't see that you will be able to wire them for a 2 ohm loan. You may have to wire them in series to be a 4/5 ohm total as the amp probably won't be 1/1.25 ohm stable.

Hi there,

This really depends if your 10" subs are 4 ohms each or 2 ohm - for this exercise, I'm presuming they are 4 ohm each.

You already know your amp can deliver 600W RMS (@ 2ohm), so you need to be careful you do not exceed the maximum RMS input power of your subs.

Normally you would wire subs in "parallel", which would reduce the circuit load to 2ohms - however, the 600W RMS power may be too high for your subs to handle.

In this case, it may be safer to wire your subs in "series" - this will increase the circuit load to 8ohms, which will effectively decrease the amps RMS power output.

Cheers,

Your best bet will be to wire 2 subs in parallel to the amp. Each sub should be rated for at least 300 watts rms at 4 ohms. This will give you a total impedance of 2 ohms, and your amp will put out 600 watts rms at that impedance. That way, each sub will receive 300 wats rms. I would not recommend wiring subs in parallel, as you will need two 1 ohm subs at 300 watts rms, which are harder to find and will be more expensive. A parallel circuit is the most efficient way to do it.

this amp is rated at 600w at 4 ohms and 1000w at 2 ohm so as long as you calculate your speakers to match the ohm specs of the amp you can hook up

parallel = pos to pos and neg to neg of the 2 speakres

2 - 8 ohm speakers in parallel = 4 omhs

2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers

2 - 1 ohm speakers in series = 2 ohms

2 - 2 ohm speakers in series = 4 ohms

parallel = pos to pos and neg to neg of the 2 speakres

2 - 8 ohm speakers in parallel = 4 omhs

2 - 4 ohm speakers in parallel = 2 ohms

series = pos to neg of the 2 speakers

2 - 1 ohm speakers in series = 2 ohms

2 - 2 ohm speakers in series = 4 ohms

well my friend either your amp is not powerful enough to push your subs or you have a sub that is shorting out cause i just had the same problem with my 2 15 kicker cvr competition subs

First off excellent choice on audio equipment, i guarantee you won't be disappointed. So your subs are dual coil 2 ohms. So wire each individual sub in series. If you don't know what this means i'll explain. On each sub there are 2 sets of wire terminals. Connect a wire from the one set's - to the other set's +. Do this on both subs and you will have the coils wired in series making each sub 4ohms. Now to hook the subs together you'll need to wire them in parallel. Now since you have your coils in series, on each sub you have one + terminal and one - terminal left. So run a wire from the + terminal remaining on each sub, and run them to your amp. Splice the ends of the two wires together and plug them into the + speaker output of the amp. Connect the two negatives in the same way and plug them into the - port on the amp. You will now have your amp running at its desired 2ohms. When wiring this disconnect the fuse on your amp power wire to avoid short problems. And if you get confused at all, and aren't sure what to do, ask again don't guess, if its done wrong you could severely damage your equipment. Hope this helped, enjoy the bass...

Hello manbearpig65,

Well, that's a 2-channel amp, so it's really best used to power a set of regular speakers.

The best power solution, for your existing components, is to wire each of your subs voice coils in parallel, resulting in a 2 ohm load, and then run each sub off a separate channel from the amp.

The amp is stable only to 4 ohms in bridged mode, so you would series the sub voice coils (8 ohm load) and then parallel them (4 ohm load) to the amp bridged connection. This will result in less power to each sub than if you ran them separately.

Hope this helps.

Sounds like the two subs wired together might be too much of a load on the amp and it is shutting off. Try wiring the two subs in series. That will reduce the load on the amp but will conversely put out less power. Less is better than none though. In any case check your amp to see what the lowest ohm rating it can see, that ohm rating is where you want your subs and if faced with a choice of either going under (lower numerically) or over (higher numerically) GO OVER!-it is much safer.

Here's an article I wrote that can help explain how to wire the subs to the amp.

OHM LOADS, SUB WIRING, OHM RELATED POWER OUTPUT

SERIES SUBWOOFER WIRING

Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the negative pole of the other voice coil (on the same sub). This will leave you with a positive pole from one voice coil and a negative pole from the other giving you the two leads that will be hooked up to the amplifier or other subs. When wiring in series, the ohms will go up numerically, and the load on the amp will go down. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

PARALLEL SUBWOOFER WIRING

Wire the positive pole from one voice coil (using wire that is as thick or thicker than your wire from amp to sub) to the positive pole of the other voice coil (on the same sub). Then wire the negative to the negative in the same way. You can then wire to the amp or other subs. When wiring in parallel the ohms will go down numerically, and the load on the amp will go up. Almost all amplifiers power output will follow this rule, except some amps such as JL Audio's “Ohm matching” D Class amps.

MULTIPLE SUBS USING SERIES AND PARALLEL WIRING

In order to match your amplifiers ohm rating you can use parallel and series wiring together, just keep things even for power distribution and to avoid phase issues.

Example: I have two “Type X 12” subs” that have dual 2ohm voice coils and have to match my “Amplifier X” ohm rating of 2ohms mono. In this case, I would wire each subwoofer in series (giving me a 4ohm load), and then wire the two subs in parallel to get my 2ohm mono load. When wiring multiple subs just, treat each sub as a voice coil and wire accordingly.

POWER OUTPUT AND OHM LOADS

For example if “Amplifier X” can make 100watts@8ohms, it would make 200watts@4ohms and 400watts@2ohms. However with every drop in ohms the amplifier is put under more pressure. It starts to create a lot of heat, distortion figures begin to climb, damping rates drop, and some amps even throw power spikes when clipping. SO BE SURE TO CHECK YOUR AMPS RATING AND DO NOT EXCEED IT!

I would look up "series" and "parallel" wiring on the net. Parallel will lower your ohms, which is good- especially for you since your amp is 1ohm. use 1 channel of your amp (unbridged...bridging an amp could increase output, but will Raise the ohms) connect the positive terminal with a wire that goes to the positive on your first sub, and from there, connect a wire from that same positive terminal to the positive terminal on your second sub. do the same thing with the neg. wire. This is called parallel wiring.

You can connect them in a series/parallel configuration. Put two of them in series and then connect the last one in parallel across the two in series. This would give you an impeadance of around 2.7 ohms. Only do this if your amp is stable at 3 ohms or less. I am not familiar with the specs of your amp. If your amp is only 4 ohm stable you can not do this.

This would also give you half the power on the two subs in series as the power for the one that is parallel. The two in series would be sharing the total output signal, where-as the one in parallel would get the entire output signal from the amp.

if you were to connect a fourth sub woofer in this configuration it could give you a 4 ohm load, by adding the fourth sub in series with the single sub that is in parallel. or in other words, yu have two sets of 2 sub woofers each in series. That gives you two 8 ohm loads (two 4 ohm subs in series is 8 ohms). Then you take the two sets of subs and parallel them (two 8 ohm loads in parallel equals 4 ohms).

If i had a picture to show you it would make sense, two subs in series that are in parallel with two subs in series.
