great info! I was into car audio in 90's. I ran four 15" subs in their own ported boxes and ran them series/parallel to get a 4 ohm load and powered the fosgate subs with 2 fosgate power 250 M's bridged together to give me over 1,200 w at a 4 ohm load. I hit 147.3 dbs once and thought that was great for 1996. Wanting to get back into it so i'm checking youtube.
Lol. That would be a st8 banger back in the day. But todays standards........
What about wiring them vertically instead of parallel?
Considering that's just two subs, that's still damn good, even today.
@@lloydhudson6463 "four 15" subs" but yeah it was the loudest stereo in my town at the time
I enjoyed the comparison of Ohm's law to drinking!!!
Lol thanks!
Yeah... just too bad they fuked up on the diagram for the water/electricity analogy right before that though... 0:55
✗ *Voltage = Pressure*
✓ Current = Flow
✗ *Resistance = Pipe Size*
Negative, rethink what you just wrote. Its the very reason municipalities use high voltage on long runs and use transformers to lower the voltage in an effort to reduce wire costs. You trade one for the other. Think commercial distributed audio.
Negative twice, high voltage lines over distance definitely has an advantage and reason, but that has nothing to do with the water analogy in question (which is wrong). Long travels have high voltage so a low current flows to deliver the power (P=IV), low V trying to supply a small town would require ridiculously high current which would melt the wires. You raise V to lower I while delivering the same power, drastically increasing efficiency as well as its not possible at low values of V. Nice way to dance around a question with a random, unrelated comment.
V is the pressure, i.e. the driving force, that pushes charges along a conductor. The very definition of Voltage relates it to an electric field, which is a vector FORCE exerted on charged species; in this case negatively charged electrons. If V is a force, moreover the driving force, then how can it be represented by the pipe size? The driving force of water is pressure obviously, which relates to electric driving force defined as voltage. Pipe size only exhibits a resistive force, it resists flow. The very words "resists flow" in the description says it all: pipe size relates to resistors.
Lastly, if pressure related to resistance then explain this. What happens to flow when pressure decreases? The flow also decreases. If a force is reduced then the body being driven by the force slows and also decreases. What happens to current when resistance decreases? It INCREASES current by decreasing resistance; thus R cannot be the pressure. By definition, resistance opposes movement, not causes it. Thats like saying applying more brakes in your car (increasing "resistance" related as driving force "pressure") will increase speed (flow); brakes are the car system's resistance, so if resistance is analogous to the pressure driving the system then increasing brake would increase speed.
Bottom line, electric R is nano-scale friction, where the flow of electrons are inhibited by colliding with atoms and repulsive forces pushing them away from desired direction of flow, causing energy loss as heat. Friction/resistance in no way can be represented by pressure; one causes energy loss and resists work and movement where the other stores energy and causes work or movement.
Can anybody tell me how i should wire multiple DVC subs to a Two channel Pro Audio amp?
The wizard was all I needed, thank you!
😉
Hahahaha 😂 me too
After viewing this video, I had to subscribe. Nice vid bro, get down to the point with no BS
Thanks bro!
My head is hurting.. and I just subscribed just now.
Pretty sure that's the first time I've heard Ohm's Law equated to getting drunk, lol!
😂😂😂
Obviously he was drunk when he made the water diagram.
Can anybody tell me how i should wire multiple DVC subs to a Two channel Pro Audio amp?
We learned Ohms law in school, it's a very simple formula..
You dont have to be a rocket scientist to wire a speaker..
Great video dude..
Keep up the good work..
Cool, thanks!
Breaks it down nicely. I appreciate the graphic work
Took many hours lol
Good video. You ought to also mention how series or parallel connection impacts the total power handling capability which also impacts amp selection.
learning this in my physics class now, subwoofers are way more interesting though haha
Great video helped me on my project 👍
YES...thanks james...cleared up everything I had questions on, very.helpful..thanks
Awesome! Glad the video helped Bob!
Some of you didn't watch this whole video, and it shows....
i watched this whole video, it made me feel stupid. i went to a more reliable source to get smarter again, the electronics section of my automotive technology text book. for a text book, it made a hell of a lot more sense then this video. i even had to rewatch the wiring diagrams he used to make sure they were correct.
Quality videos man. Big help
Liked and subbed ! You really did it up for a brother ! I watched the video a couple times to understand better and sure enough it definitely clicked 😂 thanks bud keep it up 👍🏽✌🏽
Thanks Ray!!
Very helpful and I was able to resolve my wiring issue 👊
Good video. Very informative
For calculating the impedance in parallel you don´t need that formula, just divide each speaker´s impedance by the number of speakers, so if we have 4 speakers each at 8 ohms, just divide 8/4= 2
Sebastián Díaz that’s exactly what I’ve always done! If I wire two 4 ohm dvc subs in parallel I get an1ohm load. It always get me why this confuses some people so much you just gotta take a little time and thoughtfully plan out a system
Yup, over complicating impedance is the reason why most people don’t learn how to wire subs.
@@coltonnewman8283 wouldn't that be 2?
@@jenn1022 yeah.. but thats 2 ohms per sub. Then ya parallel the 2 -2 ohm sub loads for a 1 ohm load.
@@tobiasmenough He say he paralleled (2) 4 ohm speakers. 4÷2=2. That's a 2 ohm load. What turns it into 1?
great presentation, this is the best explanation in all the videos i have seen, please keep them coming.
Thanks, will do!
Thanks guy/s very helpful !
Glad it was useful to you!
This is a very detailed explanation but confusing for people. Its way more simple to just double the ohm in series wiring and cut the ohms in half in parallel wiring
3 years ago and still saving lives😂
LOLOL
@@Qualitymobilevideo òòò oò
very good when it will pick up at all.good
,and clear.
Thank you, My friend. I am grateful for your help,
You're welcome!
Amazing i learned something new today thanks bro now do regular speakers!! if you can!!
You got it!
I think I know less now than I did before I watched this video.
True.....hahahahaa.😂😂😂
Lmfaoooooo
Bro, for real, alot of it was technical and a few parts were overcomplicated. That said, I did learn alot and am very grateful for this video.
@@drkool8168True, I got the general got it too but he definitely pit a lot of technical detail into it 😆😆
I knew how to wire up an amp and subs and everything, only thing i didnt know was how to wire up a head unit. Now after seeing this, i might accidentally switch my power and ground with each other
We clicked on this video for info......... after this video I'm overloaded
For anyone who comes across this video today. He made things WAY more complicated than necessary.
For series wiring your final ohm load is (ohm of the voice coil) x (# of voice coils)
For parallel wiring your final ohm load is (ohm of the voice coil) ÷ (# of voice coils)
For example, you have 2 DVC 4-ohm subs. That's 2 subs with 2 coils each, and each coil is 4-ohm.
So series would be 4-ohm x 4 VCs = 16-ohm
And for parallel it'd be 4-ohm ÷ 4 VCs = 1-ohm
For Series/Parallel which he commented on for just a second, it's a "little" more complicated but you just calculate the series connections first and then treat each series connection as a single voice coil of it's calculated impedance and calculate the parallel connections ohms based on that. I'm not great at explaining things, but hopefully that makes sense.
So 2 DVC 4-ohm subs, both voice coils on each sub are wired in series and then the subs are wired parallel to each other. So you calculate the total impedance of each sub separately (2 4-ohm VCs wired in series so 4-ohm x 2 VCs = 8-ohm). Then imagine each sub as a SVC 8-ohm sub and think if you wired them in parallel (8-ohm ÷ 2 VCs = 4-ohm). So 2 DVC 4-ohm subs wired in Series/Parallel would come out to 4-ohm at the amp.
Thnx for the video Henry helpfull
Love the video it saved my system
Awesome!
u can say the exact same things much simpler but i guess you do it so people click on your site, also bulbs in series.... if 1 blows up ALL will shut off not only after the bulb that blew up
ParosPasxaRide nn
Can't believe I missed that, but you're absolutely right. In an already extremely confusing video for beginners, the animation there and his explanation was highly inaccurate.
There are simpler ways you could have explained this, you didn't necessarily explain it wrong, but there are going to be people out there who aren't as experienced as some of us, and might get very confused.
Great "Alcohol Analogy" Haha. Creative way to explain ohms law. Thanks Brother!
Glad it helped!! 🤘🍻🍻🍻
This is what I call brilliant. Hey you are AWESOME
Thank you so much 😀
Also when you strap amps the impedance( ohms) are brought down which provides more bass. My sub is currently wired to .5 ohms which is kind of risky but I love it on my two Orion 12's.
Your water analogy is flawed. Voltage::pressure
Impedance::restriction in the line
Amperage::flow through the line
RustyCarnahan Yes. And thank you. Was wondering if anyone else caught that
I noticed this too, these are very good well explained videos but you're right. Voltage is pressure.
Electricity flows like water the path of least resistance. So a Water analogy is correct just not his lmao!
Yup
Well, amps measure current so that makes sense
My head is burning.. Thanks for the video.
You're welcome!
DVC Takes Multiple Subwoofers Connections To Another Level 😃😀
I started to get sleepy when the math problems started lol
Sleepy?
You stayed around that long? I couldn't do it.
you lost me with the equations
in other words: parallel wiring = less ohms (more power out of amp, but stable if within amp specs), and series wiring = more ohms (less power out of amp, but more stable)
@@VictorEstrada Yes mostly. There is another factor to consider however, that is the damping rating of the amp. Good luck finding it, as nobody rates them that way now. It is a measurement of how stable the output on the amplifier is with varying load, (which all speakers do vary in impedance with frequency, the enclosure type and size, and even temperature!). Anyway, speakers in series also have the general ability to effect each other more than speakers in parallel. So, unless the speakers are installed exactly the same, with no differences in external influences, the speakers wired in parallel will more closely match each other in motion and sound than those wired in series. And an amplifier with a higher damping factor will also be better able to prevent excessive cone excursions at higher power.
@_ David _ if (and if not the setup is rather odd) all the coils are the same impedance then you can simply divide by the number of coils.
4x 4 Ohm coils in parallel makes 4/4 = 1 Ohm final load
I have 2 8ohm speakers, that would total 16 ohms in series correct?
@@charlesd.morgan362 yes - series is calculated by simple addition.
Thank you although I feel so slow at this point no worries I'll watch until I am able to re-tune my system 🤣💯✊🏾😇 very awesome video
Yes I am connecting my woofers today. Your video answered my questions. I have dual voice coil 4 ohm. I am going with parellel
Bump it.
@@Qualitymobilevideo ok. My system is bumping HARD! However I am using a 2000 watt NEMESIS amp and the stupid thing gets hot after 20--30 min of loud bassing and it turns off.........talk about losing an erection. Ah ha guess I need a better quality amp. Looks like. Any recommendations?
I come back to this video every so Often now that I know how to wire subs , and all I have to say is you made this a lot more confusing than it had to be
He really did. Moved way too fast for people who don't know Ohm's Law at all. I just graduated with a BS in electrical engineering and was a supplemental instruction leader for Physics - Electromagnetism and Waves, which I aced as a student. I also do all my own car stereo work. Even with all that, I was barely able to follow it.
@1:6 He uses a nice example on alcohol ....LOL. its an appropriate example too. vomiting is example of power out....double lol
Lol
I took electrical 101 & 102 in college. This is right on. I'm just a little slow. LOL. I do appreciate the videos. Electricity is fascinating to me. I know I'm a nerd. LOL.🤣😂🤣😂
Right on!
dude.... make more videos. youre not boring and that's effective
3-4 a week brothaaa
Also, for people who don't understand, at 4:25, you label them as A+, A-, and B+ and B-. On an amplifier, most of the time, the power (that goes from the battery (or the alternator, for higher end systems) terminal is labeled as B+ and for people who don't really have any experience, I can see people wiring up their pos+ on their battery to the "B+" you stated on the terminal on the speaker... would have been better off labeling them 1 and 2
🤔🤔🤔🤔🤔😑😑😑😑😴😴😴😴 . Hope there's no quiz.
Great explanation bro👍🏻
Thanks!
Thank you for this video, helped me wrap my head around how I'm going to have to wire my subs to make them hit right. Probably going to do the "big 3" wiring upgrade too, not going to be very fun(audi b5, v6)
I feel like we can make this into a drinking game!
Those overfocused on power/watts should not neglect how important RMS is, plus the need for headroom to avoid clipping.
would this be fine if this is the way i want to connect my speakers, 8 ohms sub plus 8 ohms mid in parallel = 4 ohms, 2 8 ohms tweeters in series = 16 ohms then combining the two pairs in parallel connections in sakura av 735 amps?
very well edited!
Thanks!
You could also use this equation to parallel wiring, I think It's a bit easier.
((r1^-1)+(r2^-1)+(r3^-1)+..ect.)^-1
so your example would be:
((R1^-1)+(R2^-1))^-1 = ((4^-1)+(4^-1))^-1 = 2 ohm's
Emil Hammer this is the reciprical formula
(R1xR2):(R1+R2) is the best one
Omg thank u so much i switched to parallel and my kicker comp vr are booming with a ssl evo 1000 watt amp with a pc power supply. IM ONLY 13 years old
Love the drinking analogy. You're smart man. My brain exploded. I think I'm gonna take a nap
LMFAO
My subs finally sound right thankyou clipping gone an all due to knowing how to wire in series thankyou so much
Awesome! Glad we could help
And they told me there would be no math installing my subwoofer!
HA!
Rob St.Helen lmao
Lol
Rob St.Helen News flash: there is math in everything you do, even pooping.
there is no math if you just use a multi meter and have a basic understanding of wiring speakers.
He said load
Nice video man...love it..
Thanks Terry!
Great vid!
Thanks Buster!
My head hurts now
He complicated the fuck out of audio so badly
mine did to, so i pulled out my automotive text book to clear myself up
You clearly dont know what a how to is...
Its like theory vs experience - the one explains how its done and the other show how its done...
Thnx for the video very helpful
Glad you enjoyed it!
Jonny Cage. Thanks for all your help
LMFAO
series you add parallel you divide by 2 on total value. 😄
Unless you have more than 2 in parallel... then you keep adding to the division
it is slightly more complicated then that. if you have two speakers, it might be that simple but add another speaker there at 4ohm now you have 4+4+4=12 12\3 is still 4. check my other comment for specifics
He's making this over complicated so u go to his shop. And pay him to hook up 2 dvc12s to amp and a capacitor 🤣
He is it's better whatch ones that show u hands on this dude just speed thru it
Capacitors are worthless and can damage your amp. If you need one get an h/o alternator and/or second battery. Let's say you have a long bass note like in EDM music. The first second will most likely drain your caps "load" but your battery cant fill it fast enough as you amplifier is asking for. Therefore cause under voltage and possibly damaging amp. Caps are worthless...they're a gimmick. Also big 3 upgrade is good idea 👌
FAT TONY KAUAI Haun What does a capacitor have to do with this?
@@timoromeo7663 he's saying he's gonna hook you up with a cheap simple system

So if you have 3 subs at 3ohms impedance what do you run it at the amp 1, 2, or 4 ohms.
Hey James. So I’m trying to set my amp gain using a multi meter. I am running two 12” 4 ohm svc subs each rated at 400 rms. The amp I am using is rated at 2000 rms at 2 ohm. So I have my subs wired in parallel for a 2 ohm loaf. My question is what numbers do I use to find my target voltage to set my gain to. Is it the 2000w and 2 ohm of the amp or the 400w 4 ohm of the subs. Thanks.
Thankyou!!
Thanks dude
if you wire resistors in parallel they divide. to get a little more specific, if you have 2 resistors of the same value in parallel total ohms will be 1/2 of the resistor value. to simplify, 10 over 2 = 5 so two 10 ohm resistors in parallel will be 5ohms of total resistance, the same is true with voice coils only the values you are working with are more along the lines of 2 / 4 / 8 so 2 speakers with a single 4 ohm voice coil in parallel will be 2 ohms of total impedance. again 4 over 2 = two in this case 4 being the ohms 2 being the number of speakers. hope this clears it up a bit, little buddy may have gotten a little carried away although his info was 100 percent spot on. Good video
Love when people can't help but criticize on a personal level for no reason. I'm above average height for an American male thank you very much.
I don't like to stress my amps with low impedance loads . 4 ohm / channel is lowest . Running 8 ohm whenever possible . Keeps my amps cool and sounding great without stressing and over heating them . I wired my 2x10 subs at 8 ohm : 2x 4ohm in (series) instead of 2x4 ohm parallel at 2 ohms . Running my 600W Kenwood sub amp in bridge mode , pushing sub box at 8 ohms = cool , loud , clean and happy amp . Plenty of no stress tight bass .
this was beautiful to read because everyone i know just overpower subs by a lot at 1 ohm and thinking it be rocking just because it works. so i’m thinking higher ohms pushing exact power instead of overpowering. i’m thinking about getting 2 12’ 4ohm dual coil subs bc it’s able to wire to 1 ohm 2 ohm and also 4 ohm. 2500rms so i wanna get a 2ohm 5500 watt amp wire down to 4 ohms at 3600 watts. it should be a wayyyyy different type of bass
The dual 4-ohm subwoofers included in my package are pre-configured and wired up inside of the subwoofer enclosure at a 1-ohm final load. How do i wire from enclosure terminals to the mono amp.
I have a receiver that has one subwoofer out, going to a left input of an amp, that goes to a Dcv subwoofer wired in series. Should i use a y splitter at the receiver so i have a rca running to the left AND right on the amp?
if im hooking up two 8ohm speakers in parallel to become 4 ohm and i want to add a tweeter which is 4 ohm to the the left wire will the tweeters stay 4 ohm? also can i add the right side speakers to the same input pos and neg to have both side wires bridged.
#Help
i stucked to choose 😓. dual 4ohm Kicker comvr 10cvr124 or Pioneer Ts-w309d4 which one is produce more bass and which one is best... thanks
