DIY PAM8403 3W Stereo Class-D into 15W Bridge Mode Amplifier

The how to make powerful Bass bridge mode amplifier, use PAM8403 3W stereo Class D audio power amplifier board.
In addition, the circuit also uses C1815 transistor as the input signal phase reversal circuit for the amplifier PAM8403 circuit.

[@sebaz44]

yes it works! i tested it with a bc547 transistor and changed the 330k resistor for an 8.2k resistor so as not to have so much gain, i think that putting a 10k resistor would be ideal, thanks for your video man

[@ShareTechCreative]

Nice work!

[@chandradasalokuge]

Good work..thank you so much..built it and tested 🙏

[@ShareTechCreative]

Great 👍

[@melbahouse5743]

no way you can get 15 watts out of a 4.2 volt power input , can't happen .

[@mohammadalfauomey3443]

I think that .

[@luisfelipe3829]

It's bridge mode, so you can get the 2 channels in 1 with double power. So we have there 6w But if you use stereo without this circuit you are getting the same power teorically

[@edu1396]

the worst is that it is possible, I don't know about this one, but in bridge it can reach even more with other circuit boards

[@edu1396]

the datasheet doesn't say anything about bridge, but I don't doubt anything

[@ourchannel8215]

its can... add buff more signal and using lowwer ohm.. 😅😂 for 15w only...

[@franciscocastanon7463]

Fake, ya hice el circuito y suena más bajo de lo que debe sonar normalmente. No pierdan su tiempo

[@mr.nvpdiy]

Great!!!

[@ShareTechCreative]

Thanks

[@facundojano705]

in other videos, i can see arrays of this module, could i connect these arrays, (3 module for example) with this conection?

[@miguelangelbenitez8150]

de esa manera al conectar las salidas del pam8403 en modo puente (bridge, una salida con otra salida) se obtiene mas potencia ,no se si 15w pero si mas potencia que con la conexion normal

[@luisfelipe3829]

Thanks, now i know pam8403 really supports bridge mode...

[@dimasalfan6926]

Sangat ruwet

[@miguelangelbenitez8150]

lo que el hizo es adaptar una salida mono ,a la entrada de dos canales LyR ( estereo )que tiene el pam8403 y conecto las salidas de parlantes en modo bridge o puente,ahora no se si dara los 15w,yo no lo he hecho

[@rubenalcocerbalam3601]

Excelente,gracias

[@ShareTechCreative]

Glad you like it!

[@Thirteen..]

Am I right to understand that you are increasing the input gain with the help of mosfet ?

[@user-tz5gb7kw8z]

👌👌👌👌👍👋

[@hestycahaya8361]

8610 ....om... ( indonesia)....trims

[@InventorsCreation]

Pam8403 is already a bridge amp so no point adding a phase splitter at the input and connecting to both + output pins. You will not get 15W doing this. Could be a fake video with spk wires under the mat.

[@siddharthshekhawat5502]

Does it really works will I get 6w output

[@InventorsCreation]

@@siddharthshekhawat5502 3W peak into 8ohm, 6W peak into 4ohm. Note, peak not RMS, divide by 1.414 for RMS.

[@testuseraccount2344]

please guide me mono input and mono output for 4 ohm 5 watt speaker please.

[@ShareTechCreative]

You can find class-d mono circuit: XH-M125

[@LouisTomlinson_28]

Can i use 12W

[@randomstuff8286]

Can we do this to any class d board?

[@ShareTechCreative]

Yes can

[@siddharthshekhawat5502]

Does it really works

[@raji6588]

Time 5:44 my question is, speaker cable u connected left and right channel the red and white cable + connected, why do you connected that... Have any reason?

[@ShareTechCreative]

It is a correct connection according to this circuit. Thanks

[@arputharajvemban5786]

Give circuit

[@nasimsk4616]

Back ground is too much dark..

[@hoticesteve]

not possible. double is fine. Also you are cutting out useful sound due to phase cancellation. . its just a crude jugad. rest circuit is ok. It would be better to sum the L+R with a 470 ohm resistor each channel then same circuit will do very well.

[@yudhavalkyrie7568]

if true .. so 1 ch 8 watt test that and 1815 just preamp dude

[@user-iw2tl1xf8p]

Offer gain

[@edu1396]

Isso nem faz sentido, o Pam 8403 já é em Bridge de fabrica KKKKK 😂😂

[@sjsj346]

Nothing clear and nothing understand

[@edijatmiko3495]

Haha

[@electron7373]

The most you can get out is 6 watts (left amp 3 w + right amp 3 w). NOT 15W
