If you run one sub with the DVCs in parallel, you would get 2 ohms. If you run both subs with all DVCs in parallel, you would get 1 ohm.
If you run both subs with DVCs in parallel and subs in series, you would get 4 ohms.
If you run both subs with DVCs in series and subs in parallel, you would get 4 ohms.
If you run one sub DVCs in series and the other sub DVCs in parallel and both subs in parallel, you would get 1.6 ohms but the subs would not be balanced.
If you run both subs on only one coil and the subs in parallel, you would get 2 ohms (but only if the individual coils are rated for the full power)

SOURCE: how can i get a

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.

SOURCE: 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.

SOURCE: can i hook up my sub if it's wired to a 2 ohm and my amp is 4 ohm

Hi martineztag
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.
regards robotek

Wire 2 sub 4ohm


I am assuming these are subs, you didnt say, but that is my guess. do you want bass, or do you want to take it easy on your amp? do you have a terminal cup on your sub box, or just wires going into the box to the speakers? take it easy route: wire positive from amp to positive of one speaker, negative of amp to negative of the other speaker, with a jumper wire connecting the negative of the first speaker, to the positive of the second.
more bass route: run seperate positive and negative wires to each speaker, making sure to maintain proper polarity.

How to wire a crossfire vr602 2 channel amp at 4ohm and 2ohm


I would be more worried about the amp than the speakers, those subs should handle the watts with no problem. The problem will be in the amps ability to remain working with a bridged 2 ohm load. It may not even stay on without going into protect mode with a 2 ohm load. If it does stay on then it may get really hot and shut off from the heat off of the Mosfett Transistors, or it could burn the Mosfetts from driving them too hard. Basically it's your choice, run your amp hard and gain more volume or run it with slightly less sound and have a cleaner sounding more stable amp that will stay on and have less chance of being damaged. If it's not loud enough the best thing to do is buy a different amp that better suits your needs and fits the application. In your case a 2 ohm stable Mono amp is going to be your best bet or a 4 channel amp bridged into 2 channels and run with 4 ohms on each channel. Or another exact matching amp like your 2 channel amp bridge them both and have each powering 1 of your 4 ohm subs. I used two VR mono amps to power my two 12" 4 ohm subs for a few years

Can i run a 4ohm.dvc & a 3ohm.svc off of a mtx te 801d


if you wire the 4 ohm sub voice coils in parallel you will have a 2 ohm load for the Image Dynamics sub, the JL sub only being single voice coil will of course be 3 ohm.
You cannot connect them both to the amp you specified as when connected the total load will be less than 2ohms and the amp will either trip it's protection circuit or could damage the amp, My suggestion is to try each sub separately and decide on the one you like the most or obtain a matching pair for the 4ohm DVC.

How do i get my 2 4ohm dvc type r's to 2 ohms for my mrp m1000 to get the full power?


ok its all in the way you wire them, just remember when you wire your speakers in series, the ohms build(add to eachother) which would make them total of 8 ohms, and if you wire in parrallel the ohm load cuts in half (2 ohms). So you want to wire them together in parrallel then run your wire to the amp. Just so you know though, if you bridge your amp, it will also cut the ohm load in half, so you would see total of 1 ohm which gives you more power, just make sure your amp is 1 ohm stable and your subs can handle it.

Which are the differents diagrams to wire two sub dvc 4 ohms


I guess this Amp is stable down to 2 ohms. 500 Watts X 1. Unfortunately there is no way possible for you to present a 2 ohm load to the output of this amplifier. Here are your options.

Speakers in series with VC in parallel = 4 ohm total Z
Speakers in parallel with VC in parallel = 1 ohm total Z (not good)
Speakers in parallel with VC in series = 4 ohm total Z ( Whats the point)
Speakers in series with VC in series = 16 ohm total Z ( Whats the Point)

So your best option to maximize power transfer from your amp to your speakers would be option 1. (Z = Impedance)

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.

How do you wire sub speakers to change omes


if you have a 4ohm sub you can series it with another to make a 2ohm load. this is done by + from amp to + on one sub then take the - of that same sub and run it to the+ of the other sub then you only need to run a wire from - of that sub to the - on the amp. NOTE IF YOUR AMP IS BRIGED THIS IS A 1 OHM LOAD!! IF THE TOO SUBS ARE ON ONE CHANNEL THIS IS A Two OHM LOAD IF YOU ARE RUNNING 8 OHM SUBS THEN YOUR AT 4OHM PER CHANNEL AND 2 OHM BRIGED

Wiring my kicker solo-baric 15's


The best you can do is connect the dual 2 ohm voice coils of each respective sub in series (4 ohms total per sub) and then connect each sub to one channel of the amp. This will give each sub 1000W, which is the rated maximum from Kicker.
