"Put fucking 12 of them in" had my rolling 😂😂😂

need a bit more voltage on 2 of those amps which will fix the square wave. as it hasnt got enough of the high power rail it will just clip it because it cant create the full sine wave

1:10 i acually use those for DIY speakers and they are good

1st board is probably good, but may lack buffering for some inputs (unsure). 2nd board is crap, as stated, yet they've been selling them this way for years. 3rx board is probably not as good as estimated since the output inductors tend to cook on that design and the heatsink is far too small for two 100w chips. It is technically 50w + 50w + 100w, though (10%THD). They just bridge 1 chip to drive the sub, though I don't think there's any crossover/rolloff. These amps can be great and I'm using one smaller than a deck of cards as a Bluetooth amp on my mid-tower speakers, but the boards with two bridged chips claiming twice the power are suspect as some designers didn't know how to implement bridged mode properly and the boards are *never* corrected; they're just churned out so long as sells continue. Also, the heatsinks are usually too small so 1 chip is more reasonable. The power ratings are ridiculous and stated even in the datasheets at 10% THD and sellers then exaggerate that some more. No hearing person can tolerate music at 10% distortion. Some boards also have unwanted rolloff at low frequencies, so look for testing on yt or elsewhere. I recall one design where the sub channel rolled off below 100Hz while the stereo channels did not, which is obviously dumb. It's hard to know which models are good implementations of the chip datasheets and they all tend to have some hiss even with no signal, but these can be excellent values if you find one of the good boards so long as you understand that they're not going to provide the stated power cleanly and without shutting down on thermal overload after a few minutes. They're usually fine for actual listening volumes, though.

Not BAD Adam, keep making these Video's !!!

I may need to get a couple of these just for fun

great video realy educational inspired me to install one of the 3 channel amps on my mobility scooter should rock thanks for the inspiration

Thank you David 👍

As a (self-appointed) representative of TEMU, I thoroughly suggest you sell your soul more to us.

The mighty box cutter

Another great video! Would be an ideal lil amp for a classic car where the driver just wants to hide a lil setup. Looking forward to the Temu #cheapotemuboombox

How was your scope connected? One output and ground? In that case you will see only half the output voltage of a bridged amp output

Cool

Hello Adam, I just found this video and it's great, what would you suggest for an "Sound Ordinance B-8PTD" powered subwoofer, the speaker blew and the p was removed, the max is 250 watt and I would like to replace the two for a garage stereo when tinkering

no problems with too early fuzzies/distortion ? usually a "chinese amp" that is rated 50w only gives 10 clean watts before cataclysmic distortion kicks in.

Belta... get more bought! 😁 and give us an update on everything 👍🏼

Wtf that is surprising!!

On the last amp, one of the speakers were wired up in reverse. That's what made it sound like rubbish. To be honest, they were all ok. I'd be interested in replacing the heat sinks if I was to actually use it.

About the 2nd amp i have a few of them they work grate one of them is in the trash It all depends where they source the TPA. Chips from if you can find one with a real tpa amplifier chip and not a cheap clone the amp does quite well anyway did your amp pop during start up I had an issue with my ones I just added a wire on to the mute pin though a timer relay and basically shorts mute pin to ground for 5 ish seconds to stop it from poping the speakers

Good one I want moooore ;-) What about small cheap Chinese speakers?

Nice one Adam. Anymore 'Adam Eats' in the pipeline?

Always use a filthy soldering iron for best results.

Run those TPA3116 based boards at 24 volts ... you're in for a surprise. Those are full fidelity Class D boards that are actually used in consumer products. It is obvious you don't understand them or know how to make them work properly.

Try 24v next time

19:14 Speaker on the right was out of phase 😉

Why’s it look like the speakers were out of phase on the last amp?

i have had one with bluetooth. made my own bluetooth speaker with a 3 way amp (stereo and sub) it worked perfect, until it dropped, and i broke the board

Shoping like a billionaire lololol xx

Spend more and find better 👍

Everyone of the companies who use the net auction off our info. Especially that Chinese company called Apple.

For the love of sanity, please clean that soldering iron! 😀

Temu 2 $ amp with shipping 10$😂😂

i would have bought some of those tiny 2 pound amps for a boombox back in my youth, but well cheap crap from china didn't really exist back then. But you may be able to get around copyright by claiming fair use. I was wondering how those reaction channels work and it seems like as long as you have an opinion on what you are playing you can somehow get around it. Say this is a shitty song with a lot of bass and you're good to go :P haven't tested it yet though

You just gotta 'love' cheap chinese shit lol Good vid btw, entertaining n that 😀

Beric Builds sent me... he said he found another soulless temu sellout... is this true? Jk m8

Now stop messing about with crap amps and get ya bloody van done 👊🏻👊🏻👊🏻
