single stage ce amplifier, maybe 3 to 4 watts before distortion makes this unusable. And at only 12v in you'll only have a watt or 2 into 4 ohm load. 12v/2=6v because sinusoid is olny useable for half the swing -minus transistor loss 1v= 5.5v maximum sinusoidal swing divvied by 4 ohms 5.5/4= 1.37A amps times volts 1.37A*5.5V=7.5 7.5 watts peak time rms constant .707 7.5*.707= 5 watts. % watts absolute maximum but it will be horribly distorted above maybe 3 watts. So for anyone wondering its about 3 watts

The amount of people that actually believe this is incredible... there's no powersupply connected to it for god's sake... and if there is there's no speaker connected to it... there is only two external wires connected to the amplifer!🧐🤔😕

[CletusLungu-tuwr]

Where do you connect positive and negative DC power capable on the circuit

[marcusphiri]

It could have been an awesome one if he explained how it was built without showing the connection properly...and another thing is where was the power source...How was it connected without positive I can only see the ground

4:14 when that bass drops things go flying gotta love a bass that makes things move

Ganda ng pagka gawa ah hahaha lol daming na loloko dito

Upload circuit diagram,
Or else no one can understand and your video will be 50% waste

[lorgiomoralescarranza]

Falta donde conectar el cable rojo del parlante, ademas donde se instala la corrie.te de12 voltios, en parte del video se ve instalado otros cables y luego ya no estan, debe compartir el diagrama

Red wire come from back side black wire connection also connected from back you connect 2nd yellow wire with black and black also from back side

I thinking about unsubscribing from the channel. You don't answer the questions on the comments section.... no electric diagram.... Very disappointed

Привет Info Yoursel класный усилитель спасибо огромное за видео здоровья тебе удачи и всего хорошего пока 👋👍👍👍

[ashishjadhav]

Have you remove wire. After connection

[NoName-fzft]

I maked it today it's doesn't work give circuit diagram please please please please please please please please please please please please please

Desde Venezuela. Si la resistencia es Marrón-Negro-Negro, su valor es igual a 10 Ohmios no 1000 Ohmios, creo que se debe corregir la información.

[moisesalvarado]

Hello amigo, but is the big capacitor placed in reverse?

[royaltech]

But I want to ask you its need battery. Or not

[hqgprojectofficial]

I like it 😊👍❤️❤️❤️ keep it up 💪👊 I am a new Subscriber

Lmao theres a lot of bots on here but this little thing worked pretty well. Im using a plug in external phone speaker with a built in amp, PLUS this amp and it is very loud! Minor distortions at the top end but you could probably fix them with a small 1uf capacitor at the output. I hooked up several wires wrong but it still works. Absolutley terrible instructions though. Use your words.
