Hey man, can i wire 2 4ohm dvc and 2 4ohm svc together on a 2 ohm stable amp?? If ao whats the wiring scheme for it?

[@hermanbotha1449]

@@tatesmobilewashandinstalla7025 its simple like this : if you wire things in para then the ohms get added together, so 2x4ohm subs in papa=8ohm remember higher ohm means more resistance wich is bad for subs,,,,mkay. yet , if you wire 2x4ohms in series = 2ohm . what you wanna do is treat the 2 svc subs like its 1 dvc sub ....

I'm back in the bass scene after 23+ years, and the audio shop has been bringing me up to speed on all the advance changes. What a difference from the 90s.

[@jerichotm2122]

Well, I've bought a dual voice coil subwoofer, because I have two amplifiers, both of them having 4 outputs! The rear amplifier would be used to power a pair of rear speakers, and other two outputs will power the subwoofer! So, I have two channels separately powering each voice coil of the subwoofer! luckily, the amplifier supports 2 Ohm load! :)

[@donbenney2848]

Mark, just so you and your viewers know that's the complex way of figuring parallel resistance. As long as the 2 individual components are the same value.. say 2 single coil subs@ 4ohms each, you can simply take the ohms of 1 speaker and divide by the number of speakers. But this only works when the value is the same.

[@CarAudioFabrication]

The correct math is simple. I rather teach the correct way, that way in a case that they aren't all the same value, if you were doing something else electrically, it's done properly.

[@donbenney2848]

@@CarAudioFabrication I think you took that wrong. I wasn't saying your way was wrong, but neither is mine. They are both correct just used for different situations. And in the electrical field we use all 3 ways.

Got a 10 inch kicker that was a dual voice coil subwoofer and it was a little bit of a scare to see when I pulled it out of the box not realizing all I had to do was throw a jumper wire on the second voice coil. It’s not as scary any more and it is fun to learn this audio stuff slowly over time.

[@AdamLivonia]

So scary 😱

[@quitmanlott7394]

I have a couple of Skar DDX15-D2s I installed in set of vintage Pioneer HPM 1100 speakers. To drive these, I had to bi-amp them. I let the Onkyo theater amp’s front speaker terminals handle the top set of speakers, and its front speaker pre-amp outs go to a Crown XLS 2502 pro-amp, which handles the bottom 15-inch subwoofers. I did try one single coil on each speaker, as the Crown pro amp pushes this 2Ω load at a 1200-watt (RMS) potential per channel. Then I connected my Skar's 15-inch woofer's dual coils in series. the Crown pro amp pushes this 4Ω load at 775-watt (RMS) potential per channel. The bass is a bit tighter at 4Ωs, but it's not quite as loud. I do prefer a naturel well balanced sound. In this system, you can feel the bass a lot more so than hear it. I do the math a little differently from you. With a two-impedance load, times two if it is wired in series, and times One-half if it is wired in parallel. With a three-impedance load, times three if it is wired in series, and times One-third if it is wired in parallel. Do this for each step of combining loads.

[@jamespperry0420]

Or single 1 ohm coil as well. My T2S1-16 comes with a single coil at one or two ohms. Just adding that to your video I personally liked single coil, much more simplified, but people could avoid the load confusion if they just preplanned their builds better. Love your stuff keep it up man.

Currently running a Pair of JL W0V315’s (single voice coil 4ohm) on a JL RD500 amp, have the subs hooked up separate at the box, sealed enclosure, and at the amp it has “2ch” but it’s internally bridged for parallel so the amps seeing a 2ohm load, for being in a ram truck is a lot of pressure I think it’s just right for the space and the door speakers capability as well.

[@gxiong3917]

So could I use a 2 channel amp, and use each of channel to each coil on a dual voice coil subwoofer, if I was to just use 1 one side of the inputs split to both channels so that they'll receive the same sound?

[@paul7000]

So the advantage of 1 ohm load over 4 ohm load is that the amp will be cheaper! :) But I’ve heard that 4 ohm load is more precise because 1 ohm load easily looses control - is this true?

[@RodofAllTrades]

I tested this. I have a single JL 13W7D1.5 AE and I tried both 3 ohm (series) and .75 ohm (parallel) and I have settled on parallel. If you are running a decent amplifier and your electrical is solid, you shouldn't notice any sonic differences. I was hard core against low impedance configurations until I tried it for myself. Most UNREGULATED amplifiers that will run and are stable at low impedances will provide (proportionally) higher dynamic capability into lower impedances. With the 13W7 @ 3 ohms, I was fighting impedance rise and running into amplifier clipping, even using a SounDigital 5K, (rated 5,000 @ 2 ohms) which only gave me 1400-1500 watts RMS after impedance rise. I ended up going with the D4S JP 23v2 and wiring down to .75 ohm. With this configuration, I am enjoying up to 3dB of dynamic headroom and rarely ever clipping. Remember this: you're always better off having too much power than not enough. You can always gain match for the appropriate power level. Also, don't worry too much about impedance rise because it constantly changes, depending on frequency and power level. If you have a properly constructed enclosure, you will get predictable results!

[@fishrrelaxing9361]

The higher the load of the sub the quicker it will respond to signal.. also the less heat the amp generates. Much of that heat is transmitted to the sub which results in more heating of the sub.. It’s easier and cheaper to get loud per se going lower.. power is cheaper but that power is less efficient and taxes your electrical system a lot more.. There is also a lot more to this like the dampening factor of amps.. full bridges or not.. so many variables.. Ideally in a perfect world you wouldn’t have to spend 10k to get 3k of power at 8ohm and that’s how everyone would be running thier setups.. The people who know strive to use a final of 2 because you can’t decent power from the amp be a little easier on the electrical system, have tighter control of the speakers and the just have a cleaner signal to the sub that is less heat transfer more power transfer ratio.. Liken it to this for just a non specific example to give an idea.. A 3k Brazilian amp for $250 will send 3000 watts to a sub at 1ohm or 1500 watts to a sub at 2ohm.. For starters that’s a draw of 3000amps or 150amp off the battery.. However that amp is 70% efficient at 1ohm and 80% efficient at 2ohm.. the result is 70% of that 3k is not actually single the sun uses to make musical notes.. the other 30% is thermal loss. The hotter things get the less efficient they are.. just for ball park and it’s more in depth then this.. The reality is the gain between in actual signal to the speaker isn’t 1500 watts. It is but not all that is signal much is transmitted as heat.. the actual difference would be more like that 3k as it is turned into mechanical movement of the speaker is more like say 1750 watts.. the rest of that is heat.. when you meter it it will still read 3000 because heat is also power and we are only measuring for power not signal.. That same setup at 2ohm isn’t making 1500 musical watts either..it’s closer to say 1200. That is not the biggest difference one would think now when it comes to the fact one is drawing 2x as much from the electrical system overall but only generating 25% or more actual signal.. Now with all that extra heat you find things like glue on the sliders coming lose, amps clipping after they play for a while and get hot.. the sub is being driven way harder then it needs to be and it wears down quicker as well.. The thing is at the end of the day if you took two identical mid level systems and put them on the meter.. say that 3k is on a single 12 and it does a 140.5 on music off the dash.. That same sub off that same amp at 2ohm will meter say 138.5.. but it will play that 138.5 all day everyday for 24h a day 365 days a year.. It’s give and take.. the reality is a $500 amp from a name brand company that makes only 750w but that power is super clean.. would hit around a 138 on that same setup.. This is why the ogs say younger what you pay for.. 3k watts from a $200 Brazilian amp in reality isn’t the same as when 750 off say a jl or dd or dc or kicker etc.. it just isn’t.. I could go to Walmart buy a $50 sub.. build my own box for it.. and throw it in about any vehicle out there on a 500w amp run at 2ohm maybe even 4 if need be.. with proper wire, proper alternator power, proper battery setup etc and embarrass a lot of kids running around with 5k teramps on some skar subs in a prefab box on a factory agm battery and factory 120amp alternator. And I’m not bashing these companies they do what they do but the people that mostly use that stuff don’t really know what they are doing, buying etc.. My daughter runs a single skar evl in a skar evl box on a skar 800.1 amp off factory 120amp alt and a lead acid battery at that lol.. I got her doing 140.2 off the glass.. blows everyone in her school away and I’m not even a professional in this field just been doing it since early 90’s and I know how to do it right even with sub par equipment. Hell I run a Teramps 3k in my personal truck.. but that’s also off a 320amp alternated dual runs of 0/1 wire and to dc subs.. and it’s also at 2ohm not 1.. I doubled the power needed from a lower quality amp so I don’t have to drive it as hard making it not as bad.. Here is something people always miss.. you got a 3k amp.. or 2k or whatever.. you got a 120-160amp alternator.. batteries don’t supply power they store power.. you run off the alt bit the battery.. batteries don’t like to give up the power quickly.. so how do you get 3k watts power assuming the amp is 100% efficient which is impossible (this means 300amps of power drain) from a 140 alternator (which I think is standard for most mid size cars now or 160 from what is common for most trucks and larger subs now when it can only physically give about 50% of that after it runs the engine and all the electronics? It can’t! And the battery which doesn’t like to give up its power can’t cover the difference either.. it might give you another 30-40 amps at times in short bursts.. so in reality people think they are getting 3k watts but they only have 100amp or so to give.. so it’s really running at 1000 watts not 3000. And again you can clamp all the wires and speaker leads you want it it wil measure 3k all day. But that’s not 3k signal that’s just 3k power.. you may as well just plug you speakers into the electrical outlet in your house at that point cause that’s pretty much what you’re doing..

With the JL audio.12 " leaving the 1500 W RMS sub to take maximum power from my hertz amplifier. However, after listening to numerous wiring and videos, I am still at a loss for how to make sure l am pulling maximum wattage from the subwoofer output on my five channel and I've only got one amp and one sub on the other, how do I wire the one subwoofer to make sure that the amplifier is only pulling what it's supposed to which I believe is two ohms l don't think I can go down to one ohms and getting all 11 or 1200 W. from The amplifier. Please help me bro desperate Damon.

[@Anders357]

The weight difference between dual and single coil woofers, would usually mean more metal is put in the dual coils, this could potentially give higher power potential, but the significance is usually small, because whether you can push 1200 or 1400 watts through a woofer has very little impact on performance. Also it is not guaranteed that the rest of the sub can take more power, even if the coils can. However, higher moving mass usually gives lower FS. The extra coil also gives you more flexibility, and you can tap the output from 1 coil, if you want to measure it and experiment, but it will never be as good as a optic sensor or an accelerometer though, if you ponder on servo systems.

[@TLDCHWTTOS]

Ok, you make this make sense but I am still missing a piece of my puzzle. I want to run a pair of subs in stereo effect. I am thinking two single voice coil 2 ohm subs run to a two channel amp running similar rms @ 2ohms per channel. Is this the correct way to see this? Or I could even run two subs with DVC @ 2 ohms each if wired appropriately, I can see that as well. But series/parallel between the subs? I feel like this is if you are bridging the amp? The more I ponder this the more lost I feel in the numbers.

[@robin7891]

I run a single subwoofer setup. My subwoofer is D1 wired to .5 ohm on my amplifier. Due to box rise I doubt my amplifier never will see that half ohm. Is that true Mark?

[@RodofAllTrades]

It is true. Rarely if at all, will you see your sub's "resistive" rating while playing in a properly designed and constructed enclosure. Just try not to wire your subs "in the dirt". There are some amps that are rated at 1 ohm that will have no issues at .5 and if you wire at .5 ohm, chances are you will be fine. I am wired at .75 and I rise from .9 to 1.1 and my peak is 4 ohms.

Hey Mark! Thanks for this information. It is very helpful. Quick question though, I bought a 4ohm DVC subwoofer. I parallel wired it to make it 2 ohms thinking that my amp was 2 ohms stable. The amp couldn't handle high volume and that's when I realize that the amp is 4 ohms stable and not 2. So my question is, should I wire the sub in series to get 8 ohms; should I wire only one side of the coils to get 4 ohms (which you said not to on this video) or should I return my sub and change it to a 4 ohm SVC?

I have (2) 12” Polk DXi, DVC, dual 4 ohm voice coil subs, is it better to “Bridge” the amp or “Not Bridge” when wiring the two subs? (1 ohm stable amp). so this question is dual channel vs single channel wiring. “Bridge” the amp and wire the (2) subs with a “single” channel, parallel/parallel for (1 ohm). Vs “Not Bridge” the amp and wire (2) subs “dual” channel, parallel each sub (2 ohm). I haven’t tested this myself, I normally run them on the 2 channels.

I have a question for a future video since I cannot find that you handled this exact subject before I bought a new car recently and the way I want to use it combined with an audio system means that I either have to go with under(front)seat subwoofers or have a box that's super easy to take out of the car, preferably an active one (so there's literally just power, line and remote wires to hide). I can use the seat fastening brackets in the rear for a subwoofer (going to throw half the seat out, just 2 seats in the rear anyway), is this something that can be used in your opinion? Regarding underseat subwoofers I would probably go for prefab, closed, active ones there too, is there anything special to think about when going that route, like how much space is needed between the speaker and the seat for the audio to actually get out in the car? Is it hard to build underseat subwoofers on your own for the front seat? Loved your backseat underseat video but it really doesn't apply for this tight space.

Hello brother lov your channel it’s basicly a university for car sound 👏🏾 I did buy for a friend a rockford prime r2 500x1 amp with a JLaudio Tw3D4 sub. But im confused how to plug the jlaudio sub. In series (giving me 8ohm) or parallel (giving me 2ohm) The amp is rated for 500w @2ohm and 300w @4ohm Which is the best wiring parallel or series Im not worried about the warranty void because the max that the manual asks is for 400w power at the amp.

[@joshuapetherick5794]

I did the parrell 1 time i think and it burnt out a voice coil would never do again best 1 is 1 into to 2 split no burnt out voice coils performes veey well

[@chui19801]

I have a dilemma. My subwoofer is a 4 ohm single coil but the amp is rated for more power with an output of a final impedance of 2 ohms. I have the Skar SK-M9005D amp. All the other speakers are wired to a final impedance of 2 ohms. It appears that a single coil subwoofer cannot be configured to a final impedance of 2 ohms. So, I am running all midranges at 2 ohms and the subwoofer at 4 ohms. Not so sure if this configuration works well for this type of amp. Thanks for the advice if any provided.

[@nobass_stub1394]

One question I had that wasn't covered is ,,, What is the performance difference between 1 2 and 4 ohm subs ..... Does a 2ohm sub respond faster (tighter) than a 4ohm sub for SQ? Edit and also Same question but for duel or single voice coils?

[@petedetraglia4776]

The lower the ohms the more power the subwoofer can handle due to lower ohm subs have more resistance. Basically a 1 ohm sub against of 4 ohm sub = 1 ohm can handle more wattage but the 4 ohm sub would be more efficient power wise keeping your amp running cooler. The lower the ohms are the more strain on your amp but SPL will be much higher on the lower ohm sub. Also the speed of the subwoofer has nothing to do with power (wattage). Speed of a subwoofer has to do with the motor structure, cone material that it is made of, and what type of box structure you use. In my opinion sealed subwoofers are faster and more articulate than ported but there will be people who disagree. Back pressure on a sealed box controls the cone movement better in my opinion. But all subs are not built equally so a poor built sub in a sealed box may sound worse that a good sub ported if the ported box is well structure, the box is tuned well to the sub installed in it, and braced well.

How do I wire two dual voice coil 2 ohm subwoofers down to 1 ohm, right now I have them in series parallel at 2 ohms and want them at one ohm but can’t find anywhere on how to do that

[@wally7856]

You can't get them to 1 ohm, the math doesn't work out. You can get them to 0.5 ohms, 2 ohms, or 8 ohms

[@claysonwebster1622]

Would it have any effect on sound quality

[@RodofAllTrades]

Not if you have a decent amplifier and solid electrical.

I have jl 12w6v2 d4 sub. 600rms , its dual voice coil, and im running a 500rms jl amp to it, im using only 1 of the sub connections, and im not able to push the amp fully, i can only push the amp halfway. If i wire it in series or parallel, would that solve my issuse

This is extremely common. As long as the minimum impedance is acceptable for the amp you are good

[@mitchellvernon7119]

Is there any risk to pushing a 2 ohm load to two 4 ohm subs? Aren't those subs designed to run at 4 ohms? I'm confused

[@maxx4944]

the 4ohm sub i want is out of stock. i can buy the 2 ohm model and wire it to 4 ohm. Is it just as good or should i wait for the 4 ohm model to be in stock?

[@randomtube8226]

Im no expert. But I believe single voice coils are actually dual voice coils already wired for you. Running dual voice coil subs wired in parallel is best.

[@Carl_Jr]

You are correct. Using the term "dual voice coil" is a misnomer. There's always only one coil of wire which has multiple windings. In order to achieve the amount of resistance necessary to claim a speaker has an impedance of 8 ohms, 4 ohms, etc., they have to use multiple windings in order to use the necessary length of wire it takes to build that much resistance. Obviously the other approach is to use larger diameter windings (2" coil vs 3") or "taller" coils, but then you're getting into extreme applications, like long-throw woofers. Anyway, I'm going down a rabbit hole. You get the point. 👍

Hii brother, I am very well stucked can u please help me out I have a 2 channel a/b amp boss pt1000 And 2 svc 4ohm subs I want to bridge my amp and take the utmost power but its 4 ohm Is there any way to pair my subs at 2 ohm and also have the briged wattage from the amp ?? Please advise i have installed my system myself and now stucked at this phase 🙏🏻 Ty

[@edwindalida8546]

How if 1 voice coil connected and other half not. Is it apolicable or pissible?

[@jimmychua7148]

How about the wattage of single and dual voice coil. 1k watts in single and 1k watts in dual it will be double the wattage.

[@Endless_Venom]

Hello! 2 Questions! Question 1: Does a dual coil uses more watts RMS compared to a single coil? (Example: 1 Sub rated at 150 Watts RMS 4 ohm single coil would be 150 Watts RMS per sub? and a 1 Sub rated at 150 Watts RMS dual Coil 4 ohm would that mean it will be using a total of 300 Watts RMS? or would that still be 150 Watts RMS rated?) Question 2: I currently have a dual coil stock 60Watt sub installed on my doors but I want to upgrade to better subs, now the thing is, If I buy a 150 Watt RMS sual coil sub does that mean each sub will require 300 Watts? making it a total of 600 Watts RMS? PS I had a new AMP installed in my car, I believe its 500 Watts, maybe I can get some help here to be able to upgrade a bit! Thanks in advance! (Alpine R-A90S Amplifier)

[@CarAudioFabrication]

The subwoofers stated rating in watts RMS is what you should use for each subwoofer. Manufacturers don't list "per voice coil". Add up RMS based on how many subs you use

[@flyer5769]

The Cerwin Vega V104DV2. It is a dual coil with only one connection!

[@markmaese1599]

Does it matter if you run the coils of each sub in parallel, then the two subs together in series?

[@CarAudioFabrication]

You typically want to avoid series wiring between subwoofers. Better to design for parallel between subs.

[@jacquesb5248]

good explanation. now just to get a car to put some subs in..............

The following are amplifier specifications MODEL CXA1200.1 Power (watts/ch) 4 Ohm 600x1 Power (watts/ch) 2 Ohm 1200x1 Power (watts/ch) 1 Ohm 1200x1 +/-10% I don't understand the "+/-10%" of the 1 Ohm. Is the amplifier best running at 1 ohm or 2 ohms?

[@petedetraglia4776]

Its impossible for the 2 Ohm rating to be equal to the 1 ohm rating... The 1 ohm should have more wattage. This looks like a typo from the amp manufacture or store that is selling this amp. If that 1 ohm rating is true though it also means that the subwoofer should not be run at 1ohm because having a negative percentage factor in there means that amp can't handle that 1 ohm power load...

[@silver831cali3]

@@petedetraglia4776 those are from the manufacturers website. The manual basically says the same. "(RMS Power [Watts] @ 14.4V, 4Ω mono, ≤ 1% THD+N 600W x 1 @ 14.4V, 2Ω mono, ≤ 1% THD+N 1200W x 1 @ 14.4V, 1Ω mono, ≤ 1% THD+N 1200W x 1 NOTE: 2019 CXA mono amplifiers are 1Ω stable - power rating +/- 10%.)" I currently have it running at 2oh but I would like to add a second subwoofer wired at 1oh

[@milesbachelor8747]

The DVC option in my mind would seem to interfere with sound waves in a ported box, all the wires etc, but that’s probably another myth That said, might be easier to match an amp with the wiring options. No preference really.

[@RodofAllTrades]

Impedance rise on a sub that's wired in parallel vs. series is proportionally lower. I recently discovered that impedance rise is not a static number. This is important if you're trying to squeeze every bit of performance out of a setup.

[@milesbachelor8747]

@@RodofAllTrades Yes, I’m aware. Series up to 4 ohms is a goal, but I was speaking of the physical presence of additional wiring Probably a minimal interference

Can dual 2 or dual 4 be wired to 1 ohm for 2 subwoofers?

[@Anders357]

Dual 4 ohm can become 16, 4 and 1, if you use all coils. 16 is series+series, 4 is parallell+series, 1 is parallell+parallell. A pair of 2ohms can become 8, 2 or 0.5, for series+series, series+parallell or parallell+parallell. You could in theory wire one sub in series and the other in parallel, or leave one coil not connected, but why would you.

Mannnnn single coil all day

[@CarAudioFabrication]

Definitely more simple! But the flexibility of DVC can be advantageous

[@radioflyer2030]

Here's a slightly off topic but odd use case that some of you might find interesting. NOT car audio, rather commercial PA. The Peavey PVXp "800 watt" powered subwoofer uses a 15" dual voice coil driver inside the cabinet (the only time I've ever seen this done). Why? Because the engineers were feeling lazy, and the bean counters said "cut costs". They took the class D amp board from one of their existing full range cabinets that has 2 identical channels (one for the horn, one for the woofer), and connected one of the channels to one of the voice coils, and the other channel to the other voice coil. They then designed a simple mono input board with a low pass filter that feeds both channels the same signal, thus complying with the "don't send a stereo signal" rule. Side note, you car audio guys would be disgusted by the amps that these big brand name companies stuff into their powered speakers. Most of the better $200-ish amps that Big D puts on his dyno could outrun the crap that the likes of JBL, EV, QSC, RCF & others put inside professional cabinets that cost $1K - $3K USD.

Hi Mark, I am new to this Car audio stuff!, Please can you answer a couple of questions for my new build. 1, I have bought 2 dual sub woofers at 4 ohms each, And the amp I got says that it can be bridged at 4 ohms x 2 @230 watts rms each channel. ( How would I wire them up?) Question 2!, Crossovers placement! Is it better to place them nearer to the speakers or can they be put near the amplifiers in the trunk?. Any advice would be grateful. thank's.

I run single D2's at 1 ohm and dual D4's at 1 ohm in my vehicles. However, I recently won a SVC 4 ohm sub and I'm going to put it in my wife's car, matching it to an older RF Prime that is around 350 at 4 ohm, so should work well.
