Обожаю такие видео, базы 0,а вот красивых картинок вагон) даже при условии что оба динамика по 2Ома (да есть такие), а напряжение на аккумуляторе 12.5 - больше просто не выдаст под нагрузкой то мощность всего-то около 80Вт (учитываем потери), и это в случае когда идёт не музыкальный сигнал, в случае мызыкального смело делим на 2. А если учесть что динамики в основном 4-8-16 Ом то лелим ещё на 2-4-8) в среднем максимальная мощность на динамик 2Ома 41Вт

Let's see... 12 volts into an 8 ohm and 2 ohm speaker in parallel...that's 12 volts into 1.6 ohms...that's 7.5 amps at 12 volts.
That's 90 watts. I believe that's less than 4000.
Good thing, 4kw through that setup would probably catch fire.
Absolutely
Esse amplificador não trabalha com fonte simétrica
there is no way that can deliver 4kw, you have to drive your amp on like 160-200V and to247 transistors on the output, and to220 switching transistors, this amplifier measuring will be fun lol, it gonna be like 10-15W no more.
Vai ver ele tem usina nuclear, que durante o uso em local aberto, fornece os 4kw ... Ou o Amplificador é mágico, junto com os auto falants mágicos também.

12v 10Ah accumulator=120W max, class A efficiency %25=30W max.
Or 30.000 mW.
How in the hell did you get 120W? Ah is capacity, multiplying 12V*10Ah gives you 120Wh of capacity. Battery can supply a lot more than 10A.
With 12V(peak to peak) you can get around 4.2Vrms which is about 4W into 4 ohm load. Not even close to 30W.
@@setecastronomy_hc.is that USA watts or is it Canadian metric watts?
@@gerald4027 lol what?
@@setecastronomy_hc.watt has happened to volts and amps?
@@gerald4027 ???
Output can swing from 0V to 12V (fully charged SLA is at about 13V but i will ignore that) which is 4,2Vrms (ignoring voltage drop on transistors and assuming output is sine wave). Ohms law P=U^2/R=4,41W (assuming output is connected to 4 ohm speaker). You are limited by input voltage so there is no way that you can output more than 4,41W.
500W (at 4 ohms) class A amplifier needs 126,49Vppk for rails (+-63,24V).

A good example of everything a designer can do wrong in designing an audio amplifier,
I am sure that the music you hear in the demo is not the distorted crap that would be coming out of those speakers!
Yeah, same think with me
👍 agreed 💯
Without elaborating on how to improve the design, your comment isn’t very helpful tbh
Im wondering where is the differential the driver the voltage amp section is, and the output stage is a whole crap.
@@willebuoy3636
On the contrary; I saved lots and lots of people from wasting their money and time trying to build something that would never sound like the audio that accompanied the video.
If it did make any sound it would be so horrible that the builder would keep searching for what was put together incorrectly; assuming it was a first time builder's mistake and trusting the video.
The builder would then lose confidence in his ability and may never try building anything else!
It's phony videos like this that destroy the DIY community.
I would not have commented at all if the person who posted the video had also used the actual sound coming out of his design; instead of patching in high quality sound from a different source!
Then if a DIY builder liked the crappy sound they heard, and still wanted to build it, that would be fine with me......
A fraud is a fraud in any language, but to fool all the DIY people trying to get started in electronics just to get You Tube 'hits' is the ultimate travesty!
This fraud has already fooled over 6.5 Million viewers.

Why is this another clown show? One clown does a [bad] circuit and the clowns do the same - without any understanding or knowledge. These are bad news since they mislead viewers and offer no educational value. It is just click-bait.
So why is this crap? A high power amp has two stages; voltage gain and thn a driver stage that provides the current
Lets say we want 25 Watts into an 4 Ohm speaker. Watts = V x Current By Ohms Law Current = Voltage / Impedance of the speaker. So we get Watts = Voltage x Voltage divided by Impedance
25 = V x V / 4 or Voltage is 10 Volts. Since most devices like a mobile phone or CD player or MP3 or such only output a Volt or two, we need a voltage gain of at least 10.
BUT this circuit has NO Voltage gain, so it is USELESS.
.
Keep in mind this is audio so we need plus and minus voltage or in a single-nded circuit, as here, it is zero to 20 Volts.
What would this circuit give in Wattage? With 12V [Vs] and 8 Ohm speaker [R]? ROUGHLY Wattage < Vs x Vs / 4 / R
and that gives a lousy four Watts - IF the signal input is high enough.
This is a FOUR Watt Amp as shown.
What other problems are there? First the wiring is too thin to support much higher power. The wild-ass construction makes EMF interference possible. The choice of components limits a higher supply voltage. And of course no voltage stage makes it largely a joke.

4000w это 350 amperes 12v, 1000W это 90 amperes. А акумулятор ваш сколько не даст, а если что динамики по 50w, 100w более реально
This is a class A amp, you need a much bigger heatsink, or they will burn to death. Also they will get very hot when you turn up the volume. Adding a cooling fan is also a good idea
Class A circuit will run cooler with higher volume. looks low power enough with 12v
It runs cool on low volume and low bass
@@GotaSir911 Class A will suck the same amount of power all the time. or you dissipate that in the speakers or in your amplifier... you are correct for AB class amplifier tho.
its fake, battery contains Amp ,Bluetooth, and small battery pack. its the same battery he uses in all his vids. the resistor is 1 Ohm... if you built this it would send 12V directly into your speaker... both ground and speaker ground are common... the fake battery + is passing though the 1 Ohm resistor.
Olá amigo 👦. O problema é a eficiência do alto falante é muita baixa. Os atuais alto falantes precisam de muita potência para produzir pouco som e acabam produzindo muito calor. Abraços a 👪 e amigos. Ok. Brasil São Paulo.

La caja tiene mucho que ver tambien, si la caja no tiene el espacio requerido estas ahogando lu subwoofer, tambien mirar que este bien cellado donde esta montada o perdera mucho poder

Hello..can you make an amplifier for 15 inc subwoofer speakers.?

Mate You choose amplifier to the power of the speaker not the size. You can have 15” speaker with 100W of RMS power or 1000W (or more Pyle, Skar, Rockford Fostage etc.). In my opinion it’s better to have stronger amp than speakers, You don’t need to use full power so it eliminate sound distortion which can damage speakers
мощность китайская, а еще один вопрос - зачем изоляционная прокладка на одном из транзисторов если во-первых нет диэлектрика между болтом и транзистором

За тем, что первый транзистор на радиаторе B688-(PNP), а остальные D718-(NPN).

Hello, which amplifier do you recommend for all your projects to drive a 700W speaker? send me the link please, thank you.
So, looking at the transistor datasheet, it seems to provide a final power of 50W, this working with a very high voltage of 120V, between base and emitter, theoretically this circuit is a maximum of 350W real, if it worked at a voltage of 120v . but it is still a good project good work.
not good man, due if you apply that voltage to this amplifier the whole speaker will blow up due to the dc offset, if this man use this speaker as resistor at the collector it will be huge pain.
