How to Make Amazing Mini Bass Amplifier DC 12v at Home

[@dawnminilla9299]

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

[@giangianni503]

perfect ^^ so, in few words: it works, but it's useless.

[@raminvmusic]

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!🧐🤔😕

[@krozaggaming]

The circuit is connected to speaker as series like the postive of Dc directly connected on speaker and negative on to circuit

[@AlexAlex-bh8fi]

Are you serious?

[@CletusLungu-tu5wr]

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

[@krozaggaming]

Negative on the transistor emitter (right side) and positive direct on to the speaker

[@KARAN_SANI]

Nice video

[@electronicshelpcare]

nice circuit diagram

[@bhaskarshashi2891]

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

[@joshwayop]

it does work at least. (ive actually tried the circuit, there is a circuit diagram on google but its like hard to find)

[@ElinaASMR]

This is easier for beginners

[@mrinnovatorin]

@@joshwayop What should be the wattage of speaker to be used with this amplifier?

[@joshwayop]

@@mrinnovatorin I don't know I tried it on a small speaker I wouldn't use this to power a big speaker maybe 5 or 10 watts at the most.

[@mrinnovatorin]

@@joshwayop okay, thanks for your reply

[@marcusphiri7348]

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

[@joejackfierroiv3142]

There was a red and yellow wire connected and then before playing it, they disappeared...

[@olufemiademilua5075]

The thing is I think the red wire is connected to source 🤔

[@jregamey]

I think it's more of a filter. Cross over type deal. Turn audio into low frequency

Nice 👍 and very interesting

[@khumancn]

LOL 🤣

[@greecherthecreature]

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.

[@khelectronic4216]

(🇺🇸) +12v goes to the positive of the speaker. It's a directly coupled class A amplifier. (🇧🇷) +12v vai conectado ao positivo do falante. É um amplificador classe A com acoplamento direto. (🇲🇽) +12v conectará al positivo del parlante. Este es un amplificador clase A de acoplamiento directo.

[@QUIX4U]

Actually - NO DC power supply has been shown, nor has one been connected. The video ONLY shows the unit being powered by the 3.5mm cord input, from the device's headphone output. Basically it runs off approx. 1.5V AC

Simple as this and everyone need circuit diagram. It is like you can speak the language but you cannot write it. Btw you can find Class A amp circuit and apply simple high pass RC filter for a better bass.
