How To Wire Subwoofers - Parallel vs Series - Single Voice Coil and Dual Voice Coil 

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

😉

Hahahaha 😂 me too

Thanks bro!

😂😂😂

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?

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.

Cool, thanks!

Took many hours lol

Thanks, will do!

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

Awesome! Glad the video helped Bob!

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?

Thanks Ray!!

Lol

Sleepy? You stayed around that long? I couldn't do it.

You're welcome!

Glad it was useful to you!

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.

You got it!

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.

LOLOL

@@Qualitymobilevideo òòò oò

very good when it will pick up at all.good ,and clear.

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.

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.

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

Emil Hammer this is the reciprical formula

(R1xR2):(R1+R2) is the best one

Awesome!

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.

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.

Glad it helped!! 🤘🍻🍻🍻

He complicated the fuck out of audio so badly

mine did to, so i pulled out my automotive text book to clear myself up

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

Just wait your gonna wish you didnt have to worry about paying $500+ a month to own the car and another $125+ (which is great for a 25 yo) for full coverage insurance. Your gonna regret it getting old.

Glad you enjoyed it!

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

LMFAO

Got 1cozmilk15 2 coils Andy need it to be 6 omh how do I wire it

A/B class amps in particular have this problem. Does the output to the subs sound rather flat dynamically ? Kinda tinny? Like no bottom to it? Try this.. Unhook one.. leave the other one hooked positive from speaker to the positive output of the amp and same with the negative.. now turn it on at a reason able volume.. bout 35% or so.. Now as its playin take your other speaker Leads and try it both ways.. first try connecting positive to positive side of amp like the other one. If it does not double the loudness and thickness of the bass,, then reverse the polarity.. only do this by hand.. touch the leads to the terminals. Dont actually screw them to it till you find out which way is correct. Some amps require this one sub positive polarity one sub reverse polarity.. usually its only class A or class A/B amps . But even some class D amps do .. hope that helps ya ....

Thanks!

Thanks!

Your box, speakers and amp determines SQ. Mainly type of box. You want SQ(sound quality) go with a sealed box of correct size. You want SPL(sound pressure level) (loud) go with a ported box tuned to the correct Hertz the speaker likes or close to it. 1,2 or 4 ohm doesn't make any difference in SQ

Glad you enjoyed it!

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

Thank you so much 😀

👍👍👍
