2.1 Channel Bluetooth Audio Power Amplifier Board 50W×2+100W with Treble and Bass Control for DIY Bluetooth Speaker Home Theater

I could not ask for more from a sub $20 amp. I bought a 24v power adapter for it and this little guy packs a lot of punch. It runs a little warm, but nothing out of the usual.

Absolutely worth the money! If u plan on pushing subs I suggest u go a step up to the 220w! This does decent but definitely work the money

Got the non-bluetooth amp, even though the description was for one with bluetooth capability. Unfortunately was away and missed the return deadline. Had to buy another (TB, not MT). Performance-wise, they both pack a punch for how tiny they are. Not super quiet, but for general music listening around the house using a sub and a couple bookshelf speakers, an inexpensive option to an actual HT receiver.

Great sound from a tiny amp! Using an old laptop power supply to power it, works great!

The overall sound is pretty good, but the transmitter makes this weird sound when I plug it into my PC and when it’s connected to Bluetooth it will stop outputting noise whenever the audio gets quiet enough and will do that in less than one second so it’s not even just for quiet scenes in a movie or something. It’s even during music while a quiet part is happening. I plugged it into a 90 W computer charger and it seems to run fine on it.

Muy bueno

Works pretty good other than bluetooth range is approximately 5 feet then it cuts out.

Easy to put together and has good shielding which makes for good sound quality. Some reviews didn’t like that it didn’t come with a pre wired power supply, that was advantageous for my project. I was able to easily wire it up to an adapter for the 18v ryobi one battery of which I have several of. Paired with a 60w subwoofer and two 8w speakers it sounds incredible. The limitations are on how much the bass makes the pack rattle. I particularly like how I can control the speakers and bass volumes independently. Fit inside my pack in the battery opening perfectly for easy access to volume control when not wearing the pack. The amount of sound upgrade for the price I paid is phenomenal. When I get a chance I’ll include a video of it coming to life
