PAM8403 Powerful stereo Bass amplifier | mini 5 volt amplifier 

So if anyone's confused, i will explain this.. so, when you put 2 amps is parallel, you basically just divide the speaker's impedance to 2 parts, both amps handle it. Therefore, you BARELY get any output power increase at the same impedance, but you get the ability to drive lower impedance speakers, thus getting more output power.(ex:1 amp can do 3watts at 4 ohms, but can't drive 2 ohms, if you parallel 2 of them, then you get the same 3 watts at 4 ohm, but you get 5-6 watts az 2 ohms) Alright, but there's 1 really important thing! The audio source must be kept at the maximum levels at both amps to get max power! If you parallel the inputs too, you basically just wasted 3 amps and some solder because it wont do anything. You need opamps to beef up the level of EVERY channel. And last REALLY important thing in paralleling amps: ALWAYS make sure, that you give them the exact same input, because it will blow up if you dont. Also, please dont ruin speakers by putting flour in it... it makes me wanna die

awesome. I never thought of stacking the boards like that. great video

Great , PAM8403 can either blend hot cakes flour , you are such a genius man !!

This man just discovered the brand new class of amplifier it's a sandwich amplifier 😂😂😂😂

Wow amazing

That’s pretty niceeee! 😂 I might try it out and oh! Nice vid 🙂

Amazing.....incredible....

Great cascading of differential amplifier ❤️

Excelente video

Very cool. Congratulations 👏

Genious I need a help, I choose speakers which is, 1 subwoofer 4ohm 25 watt and 2 full-range 4ohm 15w. So how many of pam8403 I need to perallale? I want to know the calculation for my understanding.

also when you give input from one single source like a mobile phone doesnt it get divided by 3 and give reduced output. im looking for a multiple 3.5mm jack divider without loosing signal power. so that i can connect multiple amplifiers to single source.

Great idea.....thanks!

Awesome 💕💖💞

It will work good? If I attach 30v 8ohm speaker?

Dude I have one of those little amps or one similar to it where did you get those little plastic fork things to stick in them what are they called?

Nice mai bhi try krunga bhai thanks🙏❤🌹🌹

Amazing so nice

Good job 😎👍💯

Bro make video on using 1 single amplifier board VS using 3 amiplifer board in parallel...and test with speaker...that makes me more clear...

How long do the speakers work with that battery..?

Great bro!!❤️

Very very good idea 😄😄

دست مریزاد👏

Just awesome bro .i like this video & idea....

exelent 👍👍👍

Wow 😳

Game over speaker

nice idea😊😊😊.sorry now missing seen

two Pam8406 module There will be no harm if applied ??? Please reply me 🙏

Super bro

Wow. Very good

Great work. If it's fitted in box we get bass

I build same as like you have shown me on you video but when I connect with charger it over heat, Instead of using battery I used 5v charger but the main point is that single pm8403 doesn't overheat with the connection of charger as power.Please I need suggestion from you.

mr. @skill make, can yoy explain please, how 3 pice of pam handel 300x2 watt speaker? Need to know, i am not a electronical engineer, just love electeonic. so explain like the way I understand. 🙏

👍👍👍👍👍perfekt

Nice video

I likeeer

I love this idea. But. IT'LL PROBABLY MURDER YOUR PAMS-- I haven't tried PAM outputs in parallel like this, but most amplifiers would turn into a small firework if you did. It's because with most designs, slight differences in the amp would cause them to dump power into each other rather than the speaker and overheat. VOLTAGE DOESN'T INCREASE WHEN YOU ADD MORE PAMS, AND VOLTAGE IS WHAT DICTATES POWER-- Peak output voltage of [any number of] these little guys in parallel is still the power supply voltage, so a maximum of ~5v. Assuming the amp output swings over the full voltage range (which most don't), RMS output voltage would be 5/sqr(2) ~3.5vRMS. Power into 4 Ohm speaker is therefore (3.5 * 3.5)/4 ~ 3W RMS, the quoted figure for the amp. This setup runs on a 3.7v battery, which gives an RMS maximum of 2.6v, giving a power of only ~ 1.7w RMS per channel....(RMS - Root Mean Squared - is probably the most reliable/"honest" value used for audio signal levels.) Assuming 2 PAMs somehow did play nicely with outputs connected in parallel, the maximum output voltage would still be 3.5vRMS, so the power into 4Ohm would be the same - about 3W. Same for 10 or 100 in parallel. The only benefit would be if you had lower impedance speakers, say 2Ohm, because two amplifiers could share providing the higher current required to drive them. HERE'S AN ANALOGY-- Think of it like a compressor driving an air tool. If it works at 30psi pressure, that's like the voltage. The maximum cubic feet of air/min it can provide might be 10cf/m, which is like the current. Without tools the compressor is still at 30psi but is providing 0cf/m of air. With the tool in use, the compressor might be maintaining 30psi, but now it's pushing 8cf/m of air into a hose to do it. If you connected the outputs of two compressors together, you would STILL get 30psi but now the system can supply twice the volume of air - up to 20 cf/m. Your original air tool would work the same (because it's still working at 30 psi and taking the 8 cf/m of air it needs), but the difference would be if you ran two air tools together - or one more powerful tool - which would take the air being used to more than 10cfm. BOTTOM LINE-- So, bottom line, connecting any number in parallel won't increase the output power significantly into the same speaker . You'd need to use a lower impedance speaker setup to see any wattage increase. Not only that, but providing enough current to supply a load of 5v PAMs in parallel would be horrible. On a different tack, these little PAM things are awesome, and things like this are the guts of almost all little active speakers under 50 quid. 3w RMS on two channels is actually quite a lot of power. With the right speaker setup it would be plenty loud to fill a room, and move white dust around :) . If you need more power, just get hold of a 12v amplifier module out there for a few quid, and a 12v power supply - they're cheap as chips too. You can get 16W RMS out of those, and use a laptop 16v power supply and you get nearer 25W RMS, which is enough for a party.

Nice coba X5 pam 😂👍🏻

Bro are you still making videos today about the sound n music

i laughed hard when you put a powder on the speaker

Good 👍👍👍

Lebih bagus tambah tone control sob😍😍

Nice yr

Can I used pam8610 like pam8403?

bro can you explain it how much power we need int his case and cause i try it with 3 chips and 3.9v battery buy my chip heated.

Bhai circuit kharab nahi hoga kay

Nice

0:25 what is the name of those little black connectors?

How many watts are produced by the sum of the three and how long does the battery run?

جالبه ✔️

Ye only mobile ,laptop, Bluetooth connection se sahi chalta hai lekin kisi bhi aux se connect kerne per sound theek se nahi chalta. Mera zebronix prime 2 usb 2.0 speaker ki left ic jal gaya tha to Maine is mini amplifier ko usme fit kiya mobile, laptop,ya Bluetooth se sahi sound aa raha hai lekin set top box waley aux se sound bilkul sahi nahi aa raha. Gher gher ki aawaj aati hai. Jabki yahi zebronix prime 2 wala speaker 🔊 pahley set top box me chal raha tha. Purana board jiski ek side ki ic jal gayi thi to dubara se connection kerne per sahi se chal raha hai. Kya problems ho sakta hai.

how long did it take before the ics start to ignite ??

Tengo dos parlantes entre los dos suman 150 wts, se puede usar??? No se calienta el amplificador??

Muje lagta hai ye ic 10 minutes se jyada nahi chali hogi 😂😁😊☺

Amazing....bro plze play new song for test.

I am already set 2 pam8403 in the same connection in a amplifier board

if I use 2 pcs for 3w 15 ohm speaker,,, dose it working well??

Can we use same this method on pam8610 ? Please reply must. I m Asif from Pakistan

สวย

5:1 I'm not expected 🤣🤣🤣😂

How works, what about make many chip Amplifier like 20 Pack. Isn't very large and louder..?! 🤔🤔🤔 Those Chip are really use that, I wish buy that..!! 🤔🤔🤔

Ye kon sa speaker hai send me detail

Yai karne se kuchh nahi hoga👍❤️❤️❤️❤️❤️

5:25 Attention remember do not use nothing kind of dust in your coaxial speakers if it doest hace dust cap because it can stuck inside the coil 🤦‍♂️

Усилитель 9 ватт на канал и динамики 300ватт, гениально!

Ek se bhi vahi output milega...3 Circuit ki koi jarurat nahi

How could it be possible to run 300w speaker on 9w output? Please explain.

Bhai 50 watt ka speaker hai 5 volt amplifier Kam karega ya 12 volt amplifier jyada accha rahega

Pls try with TPA3118 also.

i did but it doesn't care what i do help me please does she have a remote or something? I turned it on with the signal from another amplifier that I have it works but she does not have this amplifier remote or something?

Add 10 more to make it up to 300w

Buenos dias hola vi un vídeo similar donde no se podian conectar en serie asi y no se escuchaba como que hacia cortó circuito

Can you please do this same with tpa3110 😀

I can do this with a 2xTPA 3118?

Bro my amplifier 3set pam8403 gets heat very fast While I am using 25w two speakers 🤔 Please give the answer
