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

[@Shanmoney187]

All I know is I followed his instructions very clearly and my box sound like an earthquake is dropping 😎😎😎 good work thanks a lot

[@jimoshrink]

These videos are crystal clear and super helpful! And ........ no background music! Nice!

[@robertslaybaugh3248]

thanks for this, i just ordered four 4 ohm dvc subs from ya'll and had no idea how to safely wire em to my two 4 ohm amps

[@dk9696]

Quite possibly the most precise and simple illustration of how to wire two subs to an amp. Thanks for taking the time to provide this!

[@YoungBlacDaStreetPoet]

I was on my way to pay a guy to hook my system up but after seeing this I just saved some money thanks

[@Impulsecinematics]

Followed you exactly despite how I had it wired before.... you my dude. You are amazing

[@odarkCarey]

Impedance is the measurement of the resistance of an active circuit. Checking the voice coil in a static state gives you the resistance value of the voice coil. These values can vary greatly depending design and application.

[@rtalcott303]

So you would just use one of the boxes terminals to hook up to the amp? That's the part I'm confused about. Im trying to do this exact setup. If you could explain on how to hook up the subs to the box and amp, that would be awesome.

[@gabrielmascia5460]

Ray Ray yes

[@HealthFitnessMartialArtsDEng]

Can that be done with single voice coil speakers? Great info!

[@jajajaJosue]

Hi guys, just to confirm, if the box I'm using has two terminal cups, am I OK to connect both subs to just one of these terminal cups on the box? Thanks for all your help guys, you're really appreciated!

[@SonicElectronix]

The jump wire is the wire that goes from one terminal to the other on the same sub. You'll need it to get a 4 ohm final impedance.

[@SonicElectronix]

Two Dual 4 ohm subwoofers will wire in Series to a 4 ohm load at the amplifier, so the MRX-M240 would be a perfect match.

[@raquskane4002]

thank you, worked like a charm just took a screen shot and was easy peasy

[@SonicElectronix]

The mono amp does not have 2 channel but it has 2 sets of terminals which makes it easier to wire to the amp. Then the amp wires it internally.

[@GHillJr83]

How would you wire it if you have two terminal cups? I have two 4 ohm subs and amp is stable from 2-4 ohm. So I wire exactly how you have it but how with two terminals?

[@ryanbotting9489]

tthank god for this video, its the only one on youtube that describes this, very professional too

[@staytuned9320]

Will this work in "bridged" mode?

[@Z06LILJ]

How do you do this if you have separate chamber box, or separate boxes for each sub?

[@ClearWater7.62]

Cool I've been looking for this. But how do I wire this up to my 2 channel amp?? Do I just use one channel ? Or do I bridge the two channels ?? Thanks

[@murderyurface3595]

You bridge the channels. You’ll have the positive atw over on one side and the negative atw on the other side (In their respective polarity locations obviously) and this leaves a gap. So it’ll look kind of like this: {**} when you’re done. The stars are the empty terminals.

[@PeachCoastLowrider]

@@murderyurface3595 thanks man just the info I needed !

[@pheonix_mac727]

This video was so helpful and easily understood 😂

[@SonicElectronix]

Yes that would be ideal if you are looking to bridge the channels together.

[@SonicElectronix]

Yes, they are just short length segments of the same size speaker wire you use to the amplifier.

[@SonicElectronix]

You can bridge your amplifier to 4 ohms and then wire your subs in series to bring them to a 4 ohm load.

[@jameswhite6581]

I was wondering the same thing

[@SonicElectronix]

You absolutely need an amplifier for speakers of that power. You would use a 4-channel amplifier and use the cross over networks. One channel will go to the crossover network, which will power the midrange and tweeter. You will be able to run your front and rear speakers from a 4-channel amp. You can get the NVX XEQ7 to take your one connection and make it into enough for those two amps.

[@SonicElectronix]

Awesome, glad that you like it. :D

[@tatesmobilewashandinstalla7025]

Well, now i know whats wrong. Much appreciated my dude.

[@SonicElectronix]

Not on a monoblock amplifier. If you have a 2-channel or 4-channel amplifier, then each sub will get its own channel and can wire to a 4 ohm load.

[@Taintedwisdomaz]

It seems you guys have every type of set up except one, I've been looking for how to wire two dual 4 ohm subs to a 2 ohm final load, and I can't find it!

[@J_Lav92]

You wouldn't be able to do that. You would need two dual two ohm subs, and wire them this way to achieve a final impedance of 2 ohms. dual 4 ohms can only be wired to a final impedance of 4 or 1 ohms. Hope this helps.

[@jhonj3478]

I'm having the same issue, I got two dual 4 ohm hx2 12". 1 ohm would be pushing the comfortable zone and I don't want to destroy my subs.

[@bigredtruck42]

There is a way to do it and its pretty simple. You simply use 1 coil on each sub. There is no rule that says you have to use both coils on a dual voice coil sub.

[@joshuadodson6874]

I always refer to this site. www.rockfordfosgate.com/rftech/woofer_wizard.asp?submitted=true&woofer_qty=2&woofer_imp=4

[@roush84leclaire21]

@@bigredtruck42 if you use one voice coil on each sub only half of the sub will work that's why it's a dual voice coil you need to single voice coil subs to do that

[@calebbrown2095]

Thanks, video helped a ton, but what would be the best gauge wire?

[@SonicElectronix]

you can drill a hole in the middle of the box inside to run your wire through it as long as you seal it back up.

[@darwinpanganiban9012]

This is the video that i looking 4 thnks alot...in this idea

[@gsukjdakid]

Do u need to drill a hole inside the subwoofer box so the wire can connect to each subwoofer.?

[@koolcats159]

no you box should have a red and black connection and that is seald around all over on the hole it is made for so air dose not leak so if you where to drill a hole you would have a air leak and your sound would be all jackt up

[@KutiaPenchod]

Kent Jackson - RMB if youd like to.. The only time to drill a hole is if it is a sealed box and if you want it ported thats when you drill a hole.. a big hole.

[@iiSup3rior]

That's awesome, also when you buy component speakers like say the type x component should I buy an amp for them or just leave it with their xovers? If I do need an amp how do I wire two amps if the head unit only has one RCA connection? One mono for the woofers and one for component speakers.

[@SonicElectronix]

That is a 2 channel amplifier, so make sure the amp is bridged properly before you connect the woofers. Check each woofers voice coil individually to make sure they are not bad.

[@cesarconh895]

Thank you! Awesome how to vid

[@HpcShadow]

thx for the info....i know how to do parallel but do i need a special kind of wire to bridge the coils ? (the jumper cable)

[@juniorsalazar5890]

Great video

[@1320Andy]

This might be a little late but I just did everything as instructed and my subs aren’t working, any recommendations?

[@samcorne4773]

Will this configuration work well with a 4 ohm monoblock amp?

[@ericgonzalez517]

say each sub is 750 watts after wiring them like this is the final watt load 750 or 1500?

[@rickbice2235]

So how do you use just the 2 wires to hook up 2 your 2 - 4 channel amp? Rockford Fosgate (PBR300X4) Rockford Fosgate (P2D4-8)

[@jdizzyfasho]

Question, with Belva 3000 watt class D monoblock do I bridge the subwoofers? ...I am running dual voice coil 4ohm NVX 15s. Thanks.

[@cameronwynn4607]

Ight. Your vids are informative, & you've been helpful. Thnx

[@jaymendoza6171]

could I do this to 2 kicker cvrs dvc to a zx1000.1 amp?

[@savinitout14]

Is this really necessary I do it completely different and sounds good

[@chicagohouseman]

I bought 2 Cerwin-Vega VEGA3104, and Cerwin-Vega Stroker STKR800.4, from you on ebay how do I wire that? (Bridged 4 ohms: 400 watts x 2 Chan.)

[@SonicElectronix]

The only difference between them is how the subwoofer is wired up to the amp and what the final impedance is. For example, two Dual 4 ohm subwoofers will wire to a 1 ohm load on the amplifier, but two Dual 2 ohm subs wire to a 2 ohm load at the amp.

[@lowdnlowd3035]

Thank you, this helped out a lot. Made it simple and easy.

[@brindham5959]

finally what conection (series or parallel ) is Right here pls explain

[@arod9276]

are you able to use automotive wire instead of speaker wire for subs?

[@Rolandrumsets]

This video was very helpful but if u wire the subs like that how would u put the subs into the box then? Also, how would bridge the amp?

[@wesleyandary90]

thats what im trying to figure out

[@Rolandrumsets]

I realized after having a giant brain fart that some boxes, that hold 2 subs, have there own space in the box for each sub so the port could be in the middle like mine is or on the side or really anywhere. so in order to wire the dvc 4 ohm subs your box would have to be open on the inside so the wires can go from one sub to the next even though the inside of the box most likely has a little wood support in the middle.

[@nextkevindurant6307]

You hook up the two leads to the box terminals

[@xiaoonin476]

Sometimes you have to think outside the box. Literally. Run the short wire like it shows then run the long ones (+,-) from sub one to the terminals leading outside the box. Do the the same with sub 2. Then connect em outside the box then into the amp. At least that's how I did it.

[@juancallado3635]

Could u do this with normal speakers or could u only do this with subs

[@jn7510]

Ok so do i bridge the final two speaker wires to my amp or wire them to either just left or just right?

[@onedeep512]

When you connect them to an amp do you just put it on one channel or use one + from one channel and - from the other channel to get to 4ohm from your amp?

[@zoominnboomin]

Or u can do this to run 4 12" 4ohm dvc's into 2ohms right?

[@loganfryer4854]

great video but I still Need some help with the math. so if I run 2 DVC 4 ohm sub's @ 1500 watt RMS , each, in series/parallel, what would be my final RMS?

[@michaelhughes1225]

if you had a sealed two sub box couldn't you wire the subwoofers down to two ohms then connect the positive and negative terminals on the box to then put them into series to achieve the same thing?

[@austinej2785]

so are we only useing one of the box terminals out of the two we have ?

[@apt.strict]

what kind of wire you use for the “jumper blue” wire?

[@Tennoz]

I have two cvx104 that I'm mounting in separate enclosures. I was wondering how to wire these in their enclosure and connect them to my 1200w min 2ohm amp. I'd like to connect each individually to my amp and keep each at 4ohms if possible.

[@MichaelLevandoski]

Can you wire them to a 8ohm load for house system

[@winstonemerson2439]

Could I wire three 4 ohm subs the same way to achieve a 4 ohm load?

[@riseagainstfb]

What if you have two separate boxes that you can't connect does it still divide the ohms when going back to the amp and what is the amp has two channels

[@earthling2022]

Hi, is it safe to have 4 speaker terminals on the subwoofer speaker box so we can decide to have in series or parallel from the outside ?

[@thatracingkid8904]

+Sonic Electronix I have two 12" subs and they're both SVC, how do I series it? Thanks in advance!!

[@JadeB628]

I know this video was made long ago. but the concept should be the same. My question is, I have one 4 ohm DVC subwoofer, plus one SVC 4 ohm midrange. (one subwoofer and one 4 ohm midrange on each channel) can this process be done the same way shown in this video? to end up with a 4-ohm load? Thanks a bunch

[@batorres1995]

Which one is positive and which one is negative to the amp?

[@anthonysandoval965]

just wondering how would it effect the sub and amp if instead of using braided speaker wire I was to wire my subs with hard wire? I await your valued opinion.

[@petec565]

speaker wire is a higher grade wire plus the insulation is better than with solid wire you would do best with a top shelf 14 g braid speaker wire

[@descolero1]

If you bridged it on a 2 channel amp will that drop it to 2 ohms since bridged cuts it in half?

how would you wire 2x 4ohm single coil subwoofers to a 2 ohm amplifier that is 4 ohms when bridged? any diagrams would be useful .

[@Rooster664]

Lower your ohms on your speakers to 2. On each speaker do positive to positive and negative to negative. That what I think but I also believe these guys have a video for that

[@Tabossco]

My Re2200 does 500 watts bridged each sub is 250 rms...with this configuration would it be ok to hook it up to my amp bridged if the manual says 4 to 8 ohms bridged?

[@midorfeed2108]

how about single voice coil ?

[@Kees4]

What if you need 4 wire outlets in your box?(2 pos, 2 neg) what do I do differently to wire it? Or do I just use 2 of the 4. Please lmk

[@TheRaneri]

How would I wire up one duel 4ohms subs to 4 ohms?

[@Tn18d]

Steven Raneri you can't, you can either connect it in series and get 8 ohms or parallel and get 2 ohms, unless you use a 2 channel amp one channel for each coil just make sure its set to mono.

[@rondjeee]

I got a 4 channel amp,Max Power 2 Ohm: 300 Watts x 4 RMS Power 4 Ohm: 110 Watts x 4 Bridge Power: 600 Watts x 2, Im about to buy a second subwoofer, exacly the same, 400 w 200 w rms 4 ohm , how to hook them up? I can make channel 1+2 one sub, and 3+4 one sub? Thanks
