I wrote it in my solution to the original question.
You are shooting for a 4 ohm load.
so a single 4 ohm driver, a dual 2 ohm driver, or (2) dual 4 ohm drivers will do the trick.
Bridge the amplifier @ 4 ohms to get the most power.

Jl1000/1 amp wiring to 4+4 ohm sub to 2ohm staple.


From your information I am assuming that you have a sub that is dual 4ohm voice coils. Also, I am assuming that you have a single channel amplifier. This is easy to get to a 2 ohm load.

First, go from the positive of the amp to the positive of both voice coils. Then go from the negative of the amp to the negative of both voice coils. You should have two sets of wires running to your sub. This is called a parallel set up and decreases the ohms load of the voice coils to a singe 2 ohms If you have a prefab box, just do the same thing, but instead of the amp, you will be wiring to the cup terminal inside. The amp will be wired regular to the cup terminal on the outside with just one wire.

This is all assuming that you are hooking up only one sub. If you attempt to hook up 2 subs like this to a mono amp, you will drop the load to 1 ohm.

hope this helps

I have a jl 2 ohm stable amp but my speakers are 4 ohm dual how can I run my speakers to where they both are at full power


Unless you have a 2 channel amp, the best you can hope for is a 4 ohm load. If you hooked both subs up in parallel, you would get a 2 ohm load for each sub. You would then have to wire them in series to equal a 4 ohm load. Even if you wired each sub in series, or a 8 ohm load, then both subs in parallel, you get a 4 ohm load. The other outlandish option is to get 2 more dual 4 ohm subs. Then you can get to a 2 ohm load. Sorry, I'm sure that's not what you wanted to hear.

Have a 2000 gmc sierra ext cab pickup and two type R swr-1042d subs and would like to know the best enclosure for the subs to get maximum performance and the best ways to hook up a one channel mono alpine...


it depends on the amp what can it handle. will it do 2 4 or 8 ohm is it 1 ohm stable are the subs dual 2 ohms or dual 4 ohms. 1042s are dual 4 ohm subs so if you wire them both in paralel it will drop both subs into a 2 ohm load for each sub that is pos of one coil to pos of sec coil then pos to pos on amp and same with neg to neg to neg on amp. now if your amp is 1 ohm stable i would do both subs the same way you will get the most power out of the amp. but itll run a littl hot if you dont have adaquate power running to the amp. now i wanna think your alpine amp maybe only 4 ohm stable. i would run both subs like i had said pos to pos then neg to neg now both subs will be a 2 ohm load so what you do to bring it back up to 4 is you run the 2 bridged subs into a series which is pos from one sub to neg of the other sub the remaining pos and neg will run to the amps pos and neg. which will make it into a 4 ohm load. now the last scenereo is your amp is 4 ohm or 2 ohm stable. this is how to wire it to 2 ohms and not 1. take one sub go pos to neg then pos to pos on amp and neg to neg on amp this will make an 8 ohm load with one sub take other sub and do the same neg to pos on sub then pos to pos on amp and neg to neg on amp this will tell amp to run a 2 ohm load. 2 ohms is a good run for these subs if the amp can handle a 2 ohm load. now if you would have given the amp model number i could have looked it up to just give you what you needed but with this short info i gave all possibilities.

How do i wire 2 4ohm single coil subs to a 2 channel 6ohm load?


If you can setup the Amp as a Mono Amp this will work for you very well unless the Amp needs a 12ω Load when setup for Mono Operations. You will want to hook the Two Subs in Series so that the Amp will see 1 8ω load. This means you will hook a wire to the Positive pole of one Sub and hook the Negative Pole to the Positive Pole of the Second Sub and hook the Negative Pole to the Amp's Negative pole. This will reduce the overall output but will end up having better reliability of the Sub since each sub will only see ½ the overall output of the Amp and you will still get the full output of the Amp.

What is the best way to wire two alpine SWR 1222D subs to a alpine PDX 1000 1


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...

How 2 wire 3 jl audio w6 v2


Hello mikey4569mky,

Unless your amp is stable below 1 ohm, there's really only one wiring solution. And that is to series the voice coils making each sub 8 ohms, then parallel all 3 subs to the amp for a 2.67 ohm load. If you parallel the voice coils and then parallel the subs, the impedance will be 0.67 ohms, much too low for most amps.

You could parallel the voice coils and then series the subs for a 6 ohm load, but the amp won't put as many watts into a 6 ohm load. Most are optimized for 4 ohms or 2 ohms. And it's not good to run subs in series anyway.

Here's the wiring diagram.

Hope this helps.

How do i wire two fifteen inch subs to 2 ohms


Hello familia_gome,

If you have 2 subs that are 2 ohms, the final impedance will be either 1 ohm if they are wired in parallel or 4 ohms if they are wired in series. You cannot get a final load of 2 ohms. Unless your amp is stable down to 1 ohm (many amps are not), your best solution would be to wire the subs in series, positive of one sub to the negative of the other sub, and the remaining positive and negative to the amp. Yes, this will result in a 4 ohm load and the amp power will be reduced. But it is better than destroying your amp with too low of a load, and the subs will work fine, just not as loud.

How can i get a 2ohm load outta 2 4ohm dvc subs can you show me how to wire the amp as well it says on the amp its 2ohm stable


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.

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

Unsureness of wiring configurations.


Mamola,

Get an amp with at least 200 Watts RMS. The RMS value is what is important about driving Subs. This could be proclaimed to be a 1000 Watt amp. REad the RMS value.

Wiring. It is better to series your Speakers to give them and your amp more reliability,

Get a Mono or Bridgeable amp. If it si bridgeable, BRidge the output as described in the manual you get. Some Amps have a diagram right on the output..

AMP+ to Sub1 +
Sub1 - to Sub2 +
Sub2 - to Amp -

Get a 4 Guage wring kit. Run your power wiring down the Drivers side, and Audio signal wiring down the Passenger side, keep the two separate.
