DIY Powerful Ultra Bass Amplifier IGBT Class A , No IC , Hi RES audio output

[@theodorenickel7462]

I see there are several questions about power output. Maybe I can clear up a few misunderstandings on this issue. The power developed by the amplifier is the result of the load vs the supplied voltage. In this case, the builder chose to label his 4 or possibly 8 ohm speaker as a 1 ohm speaker. Since it was inscribed by a Sharpie type pen as 1 ohm, I seriously doubt the genuineness of that load resistance. Lets do the math. With a 12 volt supply and a 1 ohm load, the formula reads P=E2/R. (E2 means E squared because I cant get the superscript to work on the 2.) 12 X 12 =144. 144/1 = 144 watts. It wouldn't matter if you had a 2000 amp battery, the output into this 1 ohm speaker is still 144 watts MAX. More realistically it is probably a 4 ohm speaker which would be (144 / 4 =) 36 watts. Yes you can smoke a 15 watt speaker with a 36 watt amplifier. It will take a while. I would have been more impressed if he would have put the speaker in a 1 cubic foot box, or thereabouts. It may have sounded a bit more impressive. To get 500 watts out of an amplifier to drive a 4 ohm speaker, you need at least a 45 volt battery or Power Supply capable of 12 Amps minimum. If you need a 1000 watt amplifier, plan on a 65 volt battery or power supply capable of about 17 Amps. But c'mon Technical DIY, don't try smoke your readers.

The dude is having a laugh, what's the point of a 1n cap in parallel with 3 x 0.25 R ? The transistor has no bias and will be running as a class C amplifier and the lump of Al it's mounted on doesn't qualify as a heatsink and don't get me started on the DC offset that will be applied to his 1,700 Watt 'speaker🤣

Sir, just report the video as fraud. All of this guys videos are fake. Don't waste your time.

[@dinhoometralha]

concordo com você! tem muito sensacionalismo ou mesmo exagero nesses projetos que eles dizem ter em potência kkk mais enfim ele ganha dinheiro com isso né...

[@ED-wired]

I wish I had that many transistors as you 😮

[@b7bkLove]

Amazing 🤓✨ Bro

[@9k2ah]

Is it 12v ?

[@predicandoconmelodias4349]

Me gusta la electrónica en 3D. Es bien explísita.

[@tetearalte6226]

Well done sir good job🥰👏 sir i have a questions. How you can wiring them in the right place how can you know.?

[@Matrix...777]

Pre normálne použitie je lepší klasický zdroj 12V. Kondenzátor by nemal byť priamo nalepený na tranzistore alebo chladiči. Je to trieda A, takže sa ohrieva aj keď je hudba potichu. Rýchlo sa vybije akumulátor.

super amplifier for soobwoofer. LIKE

20Ax12v=240w Why 1700 w?

Nice I like 👍

sou seu fã

[@Dheazzo]

What’s the use of that resistor that is connected to the heat sink and another end to the circuit that makes it a complete joke, I tried one of your designs and there was no output this is sh**t

[@sebsoud]

you had good luck if it didn't create fire 😅

[@9k2ah]

Ohhh ok 👍 12v I see sorry

[@pintubose960]

❤❤ good job

Hoax.ini Chanel penipu demi konten cari uang di yt menipu menyesatkan banyak penonton yg tidak mengerti.ini chn perlu dilaporkan agar di hapus oleh yt karena merugikan banyak orang.saya ahli membaca diagram rangkaian elektronik. ini rangkaian salah pembohong penipu orang ini ,!

[@yacine3828]

please show me the diagramme

[@ВикторЕршов-ъ7ь]

такие динамики 10 ват

[@nbrodeth]

thats 270 ohms not 470 red-violet- brown =270

[@ДмитрийШайдюк-г3ч]

hello, can you advise how to connect a subwoofer from a home theater to a radio in a car

[@beausky4100]

[@Dago02]

Falso porque la bateria es grande y la levanta con mucha facilidad.

[@relaxationsoothing8306]

Batrei itu palsu dalamnya adalah rangkaian amplifier dan juga batrei dan rangkaian wiireles untuk input audionya jadi terminal + dan - pada batrei sebenarnya adalah jalur output audio dari amplifier di dalam kotak batrei .pembohong yg jahat menyesatkan penonton

[@analitegnost]

Secara logika itu mungkin tapi komponen semi konduktor 3pin lebih bisa melakukan hal itu anda adalah orang yg tidak bisa menghargai karya orang lain

[@yandridiaz7222]

haha I have a 520 watt amplifier and you can hear the music all over the street, 1700 watts don't be ridiculous

Mister fake!!!! Again?????

[@demokridelectronics8551]

Faaaaaaaakeeeee

[@coccoc4960]

Disagree, look for class A amplifier circuits and see.
