Bluetooth 5.0 50W+50W+100W 2.1 Channel Subwoofer Amplifier Board TPA3116D2 HiFi Treble and Bass Control Stereo Digital Audio Amp Board for Home Theater DIY Speakers

The media could not be loaded. I bought this product like 2 weeks back, this product was excellent it blown my mind. I giving this a power supply of 12v 3a still working perfect with my 30w woofer+20w tweeter 4ohm bookshelf speakers and 100w 4ohm Sony subwoofer. It has good sound quality and nice power handling. This security mechanisms works excellent. Like the auto power cut off, or else the short circuit protection and over voltage and under voltage. Everything works perfect. Ease of use, easy setup. Nice and fast Bluetooth connectivity. Great durability, I dropped it from my table still it good doesn't have a scratch on the body. Small in size fits perfect on my desk.

Design quality is surprisingly decent. It is not fully enclosed and the sides of the box are open just like the pictures, but the PCB, solder quality, silk screen, etc are all pretty good. Components are obviously not name-brand, but off-brand resistors/capacitors/etc are OK now days it seems like (not sure about long-life though).Bluetooth connection range is OK, reaches through 2 walls in a house at least, but there was a random clicking noise in the bluetooth audio mode even when up close. That's fine for me since I'll be using the 3.5mm jack which doesn't seem to have any audio distortion that my ears can pick up. But I'd be cautions buying this if you plan to use it and use the bluetooth.Power output seems sufficient. They always lie about the "max output" on pretty much all audio equipment, but the same is true for speaker input wattage. I'm running this with about "2x40w rms" car speakers on each channel, 4 total speakers, and it is more than loud enough without clipping, powered through a 20a relay the car battery 13.5v source.

I got bored with my desktop Bose PC speaker setup - it was good, but not great. I’ve amassed quite the hoard of home theater equipment over the years so it occurred to be that two of my smaller klipsch bookshelf speakers, paired with a passive 10” ported sub might make a decent setup. So I started searching amazon for 2.1 amps and saw the $$$ options, and then this. I’m not that serious about this project so I decided to buy this $20 amp and a cheap UL listed 24v/5a dc power supply. $30 total, shipped.It all arrived today and assembly was easy - except one of the stand-offs for the top lid had stripped out threads so I was only able to get three screws in. Whatever. Everything else went smooth - got everything wired up and plugged in. It worked instantly - BUT you need to keep the source volume louder so you can keep the volume knob low on this amp because anything more than 50% volume and it emits a horrific screech. I thought it was totally broken until I turned up my PC volume and kept the amp at like 20-25%. Zero buzz or hiss with this combo and it’s plenty loud.As far as core functionality is concerned - I’m very happy. It sounds great and has just enough adjustability for the speakers/sub that it’s really easy to dial it in to my exact listening style. We’ll see how long it lasts - but for the money, even with its quirks, I think this is a solid buy.

Ordered a $19 24v 10A power supply along with this to power a busted 10" sub and some little bookshelf speakers. Wasn't expecting much, but it sounded amazing given the tiny size of thos amp. Bluetooth sounds clean to me. You can leave it full volume, and its quiet when not playing anything. When powering up, no pops or clicks, just a cute musical beep. If you have issues, try a cleaner/more powerfull power supply. Cheers.

I usually don’t provide review but this product left me with no choice. I really liked the product. I had sony speaker system with subwoofer. But due to bulky size of player from old sony. I didn’t want to use default player from sony and bought this one. And its amazing. Cheap, good quality sound. I am using only 6w power and still met my expectations. Bluetooth works fine. Thanks.

I'm not going to lie, I thought this was going to absolutely horrible but I was blown away. I ended up 3D printing a case for this if that helps to express how impressed I was. Granted, this feels cheap. The nobs are meh, the DC port sparks when you plug it in, and the wires are completely exposed, but dang it sounds nice! Its crazy. The sound fills every corner of my apartment. My wife was even impressed with this odd effect, she'd walk into various rooms and come out saying "the audio hardly changed wtf!?" I guess she likes it.I replaced the stock speakers in my car and used this to recycle the old car speakers into a makeshift boombox out of cardboard. I actually started laughing at how good the audio was for this type of setup, I still laugh about it when I turn it on. I sits on my workbench and my friends see it and instantly have questions. I turn it on and we all have a laugh, its fun really.

The amp worked good, but the Bluetooth started to have problems, requiring repeated power cycling to bring back up ... it powers 2 Pioneer 4 way 6.5s and a 6.5" dual voice coil subwoofer good though ... good enough for my son's bedroom ...

An amazing little amplifier, bang for the buck, it's sturdy and very efficient.
