A normal wiring setup to produce a 4-ohm load is what you usually see - each speaker is wired to one channel of the amp. This is series wiring. To get a 2-ohm load, you need to wire in parallel. Here's how:

Take sub A and wire the positive terminal to the positive terminal of channel 1 on the amp. Wire the negative terminal of sub A to the negative terminal of channel 2 on the amp. For sub B, it's the opposite - positive terminal of sub B to the positive terminal of channel 2, and the negative to the negative terminal of channel 1. That's parallel wiring, and will produce the 2-ohm loading (and subsequent increase in output) that you're seeking.

Infinity 1250 watt dual voice coil wiring diagram


how you wire it depends on your amp, I assume that the sub is a 4ohm DVC from what you have provided.
Parallel:
If you have an amp that can handle a 2ohm stable load you can connect one voice coil + and - to the amp and then run wires across the sub to the other side + to + and - to -

Series:
If your amp won't support 2 ohm you have to run it at 8ohm, to do this you connect from the amp to one + and to the - on the other voice coil on the sub, you then run a single wire between the + and - terminals .

Below are some images to help

Alpine x is not reading proper ohm resistance amps blew


the gmax amps are only 2ohm stable. it is odd that they both blew at the same time but if the impedence is too low to amps will fail.dual 4ohm dvc subs wired in parallel should read around 2ohms. allthought impedence varies with frequency and isnt truly stable.

I want to know the best subwoofer wiring diagram for three kicker cvr 10 inch subs, 2 of them are dvc 4 ohm and 1 is dvc 2 ohm, the amp that i am using is jl audio 500.1 1.5-4ohms stable. can anyone help...


if the amp has a 2 outputs then i would wire the two 4ohms together, and the 2ohm by itself. and if its a 4 channel output then wire them all sepretly, if its a 1 channel output then wire the two 4ohms together and leave the 2ohm sub out

How do i bridge 2-4ohm dvc's to a mono block


If you have a DVC 4ohm speaker, and you are using both voice coils, the amp is seeing a 2ohm load.
If you bridge the amp, you CAN run both subs as long as the amp is Two Ohms Stable.
Wire each subs voice coils in parallel.(Positive to positve, neg to neg.) (2ohms) each.
Then wire the two subs in series.(Neg from amp to neg of sub one, pos of sub one to neg of sub two. then pos of sub two to pos of amp.

If it sounds too hard, leave it as you are already running the amp at two ohms.

Wiring options


Hello chino2g,

For 3 DVC 4 ohm subs wired to a 2 ohm stable amp, your best option would be to wire all of the sub voice coils in series (individual 8 ohm loads) and then parallel the three subs for a final load of 2.67 ohms. There's really no other configuration. Here's the wiring diagram:

Hope this helps.

Mono amp to a 4ohm dvc sub


Hello joverstre525,

Sure, just wire both voice coils in parallel to the amp output terminals. The "wiring wizard" here shows the possible wiring options.

Hope this helps.

Why does my Legacy LSW157 sub-woofer have 2 inputs?


This is called a dual voicecoil subwoofer.

It gives wiring flexibility.

While playing only 1 voicecoil is possible - it is not recommended.

They should be wired to match your amplifier.

If it is 2ohm Mono stable - you can wire both positives and both negatives together to the amplifier so it sees a 2ohm load (parallel wiring)

If your amplifier is not 2 ohm mono stable - you have no option but to either wire up 1 set of coils... or wire them in series.

+ on amplifier to + on coil1
- on coil 1 to + on coil 2
- on coil 2 to - on amplifier

This will yeild an 8ohm load for your amplifier.

Good for sonic clarity - but you will not get the full potential from your amplifier.

Wiring


You have 2 subs and 2 amps right?In that case make sure that the amps are capable of stable 1ohm load and also you'll need a lot of power and 4 gauge power cable for each amp with fuse of course.
Now....take one sub and connect the (-) with the (-) and the (+) with the (+).Now you have one (+) and one(-) to connect to the amp.Do the same with the other sub and you're ready to rock!!

huge shared common space slot loaded box (size depends on sub 10", 12" 15" you need to clarify that please) the amp specs on earthquakes site say the phd5000 is rated at a max output of 5k watts at 1 ohm 3k watts at 2 ohm so, with 3 dvc 2 ohm subs you only have 3 options of which only 2 will be a usable solution:

1. 3- 2ohm dvc series at sub parralel at amp = about 1.33 ohms at the amplifier this is the best option to get the most power to the subs as each sub will produce a 4 ohm load then wire each one to the amp the amp sees 3 4 ohm parralel loads which = 1.33 ohm so based on the amp specs you would be close to 1200 watts per sub.

2. 3- 2ohm dvc wired in series at sub and all 3 subs series wired together very difficult to wireand will give you a 12 ohm load which is next to no power at all (not a viable solution)

3. 2- 2ohm dvc parralel wired to each other and then at amp the amp sees a 1 ohm load and makes 5k watts max but you can only (REREAD THAT LINE! ONLY USE 2 SUBS IN THIS WAY) WHICH GIVES THE MOST POWER BUT ONLY USES 2 SUBS
