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 Wireless 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.

So I've been around for a while and audio is a passion of mine so I don't say this lightly, but this is definitely top 5 things I've ever bought for $20. It's loud , it's clear , it's easy and it's small. Its not that sturdy but but I'm not even docking any points for that... just make sure that you get a 24 V power supply for it that's 5 amps or higher. 5 is the minimum amount. It'll take, but it doesn't say that anywhere on the page here or in the in the description that I can find, so there you go.

I got bored with my desktop Bose PC speaker setup - it’s 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 by Onkyo (not a good sub at all) 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 when 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 10-15%. Zero buzz or hiss with this combo and 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.

My buddy gave me some brand new sonance outdoor speakers. I was going to use them indoor as presence speakers but noticed the output and ohm rating were different than my receiver.I decided for $0.18 I couldn’t go wrong. (Used my Amazon points). Anyways, I was shocked after I assembled and wired this amp board up. The speakers sound perfect with no harshness or dropping out. I opted to go with a 24v 6ah power supply to get the full potential.My buddy who gave them to me was shocked by the clarity and the sound the little board produces. It syncs up immediately with the Bluetooth on my iPhone so I’m able to play Pandora outside with crisp clear sound.Can’t wait to buy the buriable bass channel. If it delivers the way the other two channels do then my bass will be digging deep outside too.

Awesome for the price! I have a passive 2.1 system from ages ago that this powered very well, and it was able to power my subwoofer louder than I wanted it which I can't say about more expensive ampsThere was a low buzz when the volume was turned up without anything playing, so this would probably be best suited in a garage, but for under $30 I was still very impressed

Works great and really like the extra treble and base controls plus the sub woofer output.

The amp in my Klipsch ProMedia 2.1 THX speakers gave out and rather than throw out perfectly good speakers, I purchased this unit along with a power supply for a fraction of the cost of a new desktop setup. Super easy to hook my subwoofer and desktop speakers to this unit and the sound is incredible. In fact, it is much richer and has more fullness than the original Klipsch amp. Definitely a good purchase.

I've purchased 2 of these so far, both work great. Sound good and clean using both Skar and Kicker brand car speakers. Bluetooth connects easy and has good range, even when mounted inside of a metal ammo box speaker. No complaints, am about to buy another one. One note, the Bluetooth is an unsecured connection, so anyone can connect without a password, but once you connect your device to it, if someone else trys to connect, you will get a message requesting to release the connection to another device, on your device.
