# How to Wire Two Dual 4 ohm Subwoofers to a 1 ohm Final Impedance | Car Audio 101

(electronic music) – Hey guys, it’s Brendan with

Sonic Electronics and today we’re going to be showing you how to wire these two dual forum best car amplifier

subs in parallel to equal a one ohm final impedance. All right guys, so here

we have our MVX VCW104’s which are a dual voice-coil

subwoofer at 4 ohms per coil, and one way

to be able to tell that, you’ll see two sets of terminals. One on each side of the actual basket. Now I prefer to actual

test the impedance prior to wiring up the woofers

just to verify that I do have the correct impedance or

resting impedance per coil. And in order to do so, we’re

basically going to take our multi-meter, put our

setting on the ohm setting, or the impedance setting, as

you see what I just did here. And we’re going to go ahead and

measure with our test leads. Now, before you measure the

impedance of the woofer, make sure that you have the

woofer on a flat surface with the cone facing the sky,

because if we do not have the cone facing the sky and we

try to measure the impedance it will constantly fluctuate. I’m going to go ahead and

hook up one coil here. Now it does not matter

which one goes to positive or negative on the test leads. You’ll see here that the

impedance of each coil is 4.0, perfect. So we’re now ready to wire

up our subwoofers here and you’ll notice I’ve got

some speaker wire on the table. We actually have a set of four jumpers. Two are going to be positive

which today we’re going to be utilizing the blue

wire for positive jumper, we have two of the negative

grey, so the color’s going to be grey for negative on our subwoofer. And we also have another

jumper that’s going to go in between the two subs

to parallel them together within the box. So let’s go ahead and get started here. First, we’re going to go ahead and start connecting all positives

and all negatives together. So positives are going

to go with positives, as you see here. Negative, we have our

little jumper to parallel the two woofers in between,

so just go ahead and twist the positive with the positive. Insert it into voice coil number two. And we have our negative

jumper, also going to go with negative on voice coil number two. Okay, and once we’ve done

that, we have our jumper. We also have two extra positive

and negative jumpers here. So what we’re just going

to do is actually join up the positive and positive,

negative with negative, and now attach that to

our other voice coil on our number two subwoofers. So we got positive on the positive, negative going to negative,

and we have two leftover wires, basically jumpers,

we got one going to positive terminal on the last voice

coil, and negative going to the last negative on the

last voice coil as well. Just bring these around. Now this set of wires

right here is going to go to your box terminal on the

inside of your enclosure from the box terminal

to the outputs of your monoblock amplifier. So what we’re going to do is

join up our last negatives. And our last positives. Going to swing that around here. All right, so we’ve just

successfully wired our dual forum subs in parallel to equal

a final one ohm impedance. Now when parallel wiring option,

you just have to remember you’re connecting all

negatives together, and then all positives together, to each coil. So once we’ve wired

our woofers in parallel it’s now time to double

check our work and verify that we have a final one ohm impedance. Now mind you, with the

meter, we want to go ahead and make sure

that we do put it on the ohm setting or the

resistance setting to measure the impedance of these two

woofers wired in parallel. Also it does not matter

which leads go to which on the positive or

negative from the meter to the subwoofer. So I’m going to go ahead

and attach our leads here real quick. And we’ll notice that we

have a final impedance of one ohm. Perfect. Now it may fluctuate as

you saw there on the meter, maybe between 1.1, 1.2. It does not matter, .1,

.2 off is letting us know that we have a final Best Car Amplifier for The Money impedance of one ohms. It’s going to stabilize. So again, that’s how

you wire your dual forum subs in parallel to equal

a one ohm final impedance. I’m Brendan with Sonic

Haha those r not vcw subs they're the vsw duuuh

I got a 2 ohm final impedance by doing this wiring to my (2) 4 ohm DVC Rockford Fosgate P3D4 subs. What did i do wrong?

what if you have an 2 channel amplifier thats non bridgeable? how do you wire the 2 4ohm dvc to 1 ohm stable on a 2 ch amp?

I have an MD Sound Amp 2000w 2 Ohm stable mono block (four channel) and two 12" 1200w max 4 Ohms subs. I have them in series-parallel and down to 2 Ohm. The amp is bridged (left negative and right positive channels) According to Ohm´s Law 1200w * 2 Ohms = 2400w Square root of 2400 is 48.9 volts. The amp at full Gain gives 46 volts only. So I have it at 43v. The subs moves but not fully, so my question is can I down them to 1 Ohm without blowing anything?

can anyone help me. what would i do to get 2ohms?????

how about to wire 4 ohm into 1 ohm amp? Is that even possible?

With a 300 watts at 2 ohms monoblock. 2 subs with 300 rms and 4DVC….. If I make final impedance at 1 ohm does that mean sub will handle both speakers better? Recently got kicker CX600.5. And got 2 CompD 300 watts DVC at 4 ohms. What would be the best way to connect the speakers.

thx for this

what amp would I need for a these exact setup the subs being 600 watts each. would I need a amp capable of 600 watts or an amp capable of 1200 to power both?

im so confused.

Thanks guys i did 4 kicker 15s in my 89 caprice man it bumps so hard!!

do you do the same for 4 subs?

what about the subs that are already wired directly to the sub such as the American bass XFL1244

Hello I have 2 15s Memphis mojos Xseries with dual coils like this and I want to connect it to a Memphis mojo mcd4k amp I believe it's a 1ohm stable amp but I connected it like this and it got really hot so idk what's going on I have it connected in series right now but I want them to be at 1 ohm so I can be getting all the power out of the amp

does this method only works for subs connected to car amps or can this work on home amps as well?

so just one sub that is dvc weird like this is 1 ohm or it has to be 2 subs to get 1 ohm on 4 ohm dvc

Hi , I have kanwood kac-9106d , can I pair it to two kicker 12" 40cwr122 subs?

so higher the ohms on a stock speaker is louder?

and then making them a lower ohm together is loudest?

im confused my amp has 2 sets of terminals for each subwoofer and my box has 2 sets of terminals for each subwoofer.can I just hook up each speaker to each terminal? on the amp and box?

Reading these comments, and som of the answers given , is funnier than watching old reruns of the three stooges!!!! Rotflmao!!

ok once I have the one positive and one negative at the ends after the Subs are all connected then what? my Dd m1c has 2 sets of speaker connections, left and right…do I just plug the positive to positive on the amp and same with negative?

This is to sonic electronics I just bought an 2400 watt 1D amp and when I have them ran 1 ohm it does not sound good at all and when I unplug one it sounds OK but not like it should I had a 2000 watt power acoustic but RMS is 1200 watts worked perfectly until it blew that is all I changed out any ideas

What if you have two different boxes

Does the RMS change on the subwoofer. let's say if you have two 500 RMS subwoofer 500rms+500rms=1000rms

when you wire the speakers like this . say your running 600w into them are they both getting the full 600w or they are get each 300w ?

What gauge wiring for the speakers?

how thick is the wire recommended? I have 1700Rms 1ohm amp and two pioneer TS-W3003D (600Rms)

Do you wire two dual 2ohm subwoofers at a 1 ohm impedance the same way you did these 4ohm subwoofers?

I wired my subs to my girls nipple piercings @ 1ohm when she was sleeping…and now I'm single. Can you tell me how to re-wire my subs back up to get my girl back? Thanks man, you're a real life saver.

So I got Single X-12 D4 Sub Pro 12" Dual 4-ohm 1250w Rms Loud Bass Subwoofer and Amplifier is Mono bass 1Channel 1-Ohm rate for 3000W. I currently been connecting it as Parallel which Positive to Positive and Negative to negative but, my wire run from Amp to Sub tend to keep getting burnt out. Whats wrong, or whats the best way I should do or run?? Thanks in advances.

This is to SonicElectronix. I recently ordered a Lanzar Optidrive 2001d 2000-Watt Amp with 2 Q Power 3400-Watt Deluxe DVC 4 Ohm 12-Inch Subwoofers. Should I do 4 Ohm to 2 Ohm or this particular method here, which is 4 Ohm to 1 Ohm?

i have a M1886i MA Audio amp ! which is

Max Power (Watts) 1000

# of Channels 1 (Mono)

RMS Power (Watts Per Channel) 500 x 1 @ 4

Car Amplifier Features Crossover, Thermal Protection

i needed to know Do I wire my speakers in series or parallel ?

these are the speakers

Hifonics BRZ15D4 Brutus 15" 1200 Watt DVC 4-Ohm Car Audio Power Subwoofer

Peak Power: 1200 watts

RMS Power: 600 watts

Impedance: 4 Ohm

Polypropylene cone

I wired my subs up this way. box had 2 chambers so I drilled a hole to run the wire outside the box and back into the other chamber i had a buddy bring his multi meter to work today and im at 1.7 ohms which isnt getting me the 1000 watts i want out of my amp at 1ohm

is this possible with two 2 ohm DVC subs?

How about do the same video but with down to 2 ohms

let me make it simple, plug all positives terminals together with the same red wire straight to the amplifier. Now do the same with a negative terminals using black or silver wire.

what kind of amp should I buy if it's 1ohm stable

gay!!!

so does only one set of wires come from box to amp or two sets

So lets say those are 500 watt rms rated subs and you wired them directly to a 1000 watt monoblock [email protected] Each of those subs would be getting 500 watts each even though they are connected with only one wire to the monoblock amp correct?

can you wire a single dvc 4ohm speaker to 1ohm?

I'm looking to get subwoofers that are designed with dual 4 ohm voice coils, for an 8 ohm or 2 ohm configuration. Is it possible to configure them in the way this video shows to a monoblock amplifier? If not, what's the best way to get the full 600 watts of RMS (x's 2) from the subs?

I have to 15-inch qpower dual 4-ohm subwoofers would they be able to handle it on a 5000 Watt amp there 2000 a peace

Hello there I have a audio pipe 3000d & 2 kicker cvr's 15's dvc's subs how should I wire them

Hi my homie ordered a hifonics zues 1200 watt amp and we hooked two dual 4 subs to 1 ohm and the amps bass knob turns red when its hitting real hard? does this mean something in the wiring is off? i made sure everything was good the only thing i could think of is that the car is too old to take the amps power because it was dimming very hard. have you ever heard of this issue?

is it the same with four subwoofers

4 HTC

Bruh i got the same subs too

How do you run these to the amp just into 1 channel can you make 2 dual voice coil 4 ohms into amp at 2 ohms 1 speaker on each channel?

What is the model of those nvx subs?

I wired My 2 DVC 4 ohm Subs In Parrelel Wanted A Final Impedence Of 1 ohm But when I Check It with A Multimeter It Reads 2 ohm Instead Of How I have it Wired

Before i begin here's my setup so far… Keep in mind this is my first system build over 2000 watts….

Now when playing the system hit will hit hard for about a quarter of the song with my bass nob at half power and then my radio will cut off and reboot itself at the same volume it was before and repeat this cycle until i lower my bass nob to about its third or fourth notch (there's a total of 10 notches) when i turn the bass nob all the way off the radio can enter the danger zone (cut off point) and play continuously. I have done some research and i think its the amps impedance capacity (which is 1 ohm stable). Will dropping my sub impedance to 1 ohm from its current .5 ohms stop this problem or is it a lack of power issue… because the amp seem to be doing fine playing at .5 ohms besides the power cut-outs at the headunit. it stays very cool, i mean i can play certain songs all the way through on repeat and place my hand flat on the amp and hold it there. Even after shut offs (the headunit blackouts) it still room temp. need suggestions….. any help is very appreciated

how do you wire 5 4ohm dvc subs to 1ohm

I have 2 dual 4 ohm 15s at 2600 watts each with a rms of 1300 each. I wired them parallel to 1 ohm like in the video. Problem is I have a 500 watt power amp. Am I at risk of burning my amp or speakers up hooking them up. Haven't tested them yet

ok I have a kicker mono block amp with 2 terminals at 2 ohms , can I wire the subs that are 4 ohms an convert each sub to 2 ohms an connect each sub to its own terminal

Oh my gosh guys watch the video again I read som of your comments like running 1 wire from each speaker that's series . You will increase the resistance that way you need to run them parallel which is all the positives together and all the negatives. You can do more speakers search for series / parallel wiring

Can somwone link a place to purchase those wires

Dad my alternator is very hot and my battery's flat again.

Ok now how do you install this into a sealed subwoofer????

can you wire each sub seperatly to 2 ohms then connect them to a mono block? will the mono block see it at 1 ohm?

does people really not know this

can u guys make a vid of how to hook uo to dual 4ohm subs to 2 ohm stable amp plzzz

What if my enclosure has 2 terminals? Can I hook them up through only 1 set of them

Can you than bridge that to the amp or run it on one channel if I have a 2 channel class d rated amp?

what hits harder putting at 1ohm or what can someone plz explain it to me.

WHAT IS THE WIRE GAUGE!!!

it never did work for me

does it make your amp give more power at 1ohm.

how to wire two dual 4 ohm subwoofers to a 2 ohm final impedance

So if I have two subs that are 600 watts rms at 4 ohms each and i wire them down to one ohm. How many rms will they be at 1 ohm? or does the rms not change?

My sundown monoblock amp has 2 positive and negative pairings how would I wire this ?

This isn't how to wire a subwoofer properly

Let me just get this str8, two 4ohmdvc subs will work at 1ohm amp stable and 0.5 if I try/do that… now what about two 2ohmdvc subwoofers that shit won’t work on 0.5?

If u had an enclosure with two sets of box terminals guessing one per sub in this cause you would only use one terminal and not use the other

"two subs are better than one"

Wait so what wire do I use if I'm doing a series? Do I use the negative wire or positive wire to do series?

Does the amp have to be monoblock to get the 1ohm ?

How do you turn that 1 ohm to 2 ohm? Or how do i wire the 2 dvc 4 ohms to 2 ohms?

How to wire two dual 4 ohm subs to a 2 Ohm amp?

Hi. Can I connect my 2 instrumental speakers,1 mid and 1 tweeter in my 3 way _ are rated 8 ohms and my amp is rated 8 ohms. Thanks for your help.

It would make more sense to show how to get 4ohm .

Then you can use them bridged to any 2 channel amp.

So why is the diagram I have for 1ohm to a mono blck amp totally different???

hey. i have a GM-D9601 pioneer 1200w RMS 1ohm stable and 2 dual 4ohm 600watts RMS pioneer,i have wired them in parallel and about one month later they blow off the amplifier.can you help me if there's a risk the sub blow the amplifier or another problem.?

Want to explain how to do it when the box is sealed cause I am not trying to wreak my box by drilling a hold unless I have too. Thank you

I did this and my meter says 0.7 0.8 on 2 kicker l7 is that ok?

So if you originally have 2 svc 4 ohm 12” subs rated at 150w rms on a 2 channel amp. If you wire it in parallel at 2 ohm would it still require the same amount rms or more?

What are the essentials in watt speakers

Great videos thank you very much

The dual 4-ohm subwoofers included in my enclosure are pre-configured and wired up inside of the subwoofer enclosure at a 1-ohm final load. My amp is 1 ohm stable how do wire the box terminals to amp?

What’s if I have 2 subs dual 2 ohm can i turn then into 1 ohm ?

What if I have a ported box for both? I'm so confused bro.

I have 4 cvr 12s i do all them the same way?and i got a 1 channel old asa 1500.1 powerbass

Today I did a good job

your fucking stupid

I have 1dvc 4ohm 400w rms sub and I’m looking at buying an amp that has 1200w rms at 1ohm, 800w rms at 2ohm, 500w rms at 4ohm which for the 1 sub I have I would just wire it in series for a 4 ohm 500w application, but my question is if I was to purchase a second sub exactly the same a 4ohm 500w wouldn’t be enough but would it be ok to wire it for 1ohm 1200w? Or is that going to be too much power and damage my subs? I’m like an advanced beginner and just trying to learn thanks in advanced

So what coil do we connect to the amp ?? Do we connect coil 1 to coil 2 x coil 2 to coil 1 and iim guessing it don’t matter what speaker 🔈 do we connect to the amp.. do happend to know what amp will make 2 kicker L7 15 4ohm bump pretty good they going on a crew cab s10

If subs can't handle the power of the amp will the bass cut off and on????

The question I'd really like answered is how can I do this when my speaker cable is too thick (12 gauge)? If the answer is "get thinner speaker cable" – epic fail.

Hello, I was hoping you could give me some advice, I have an old Rocford Fosgate Punch 201s 2ch 600w amp (amp says it's 4ohm stable bridged) and have been runnig it bridged to a 12" 4ohm alpine type-e sub and now I want to add a 8" dual voice coil sub under my trucks center jump seat, Can I just hook each sub to each channel, or wire them in series or parallel with amp bridged? Thanks, love the vids you guys put up here

My jumpers are pretty long ? Will that affect subwoofer output ? Should i shorten the speaker wire ?
