High-Quality 2.1 Channels Bluetooth 5.0 Subwoofer Class D TPA3116D2 Amplifier/Receiver Board - 50W+50W+100W, Adjustable Bass Frequency, DC 12-24V Review

I used this amplifier to connect loudspeakers in the garage. I can play music via bluetooth or an aux port. It even comes with a small screwdriver for assembly. In general very satisfied. Definitely recommend.

The sound system connected to my garage works better than expected. Before using a 24V 5A power supply I used 15V 1.5A which still worked great but cut out at higher volume. You can't go wrong with this product.

So far I'm impressed. Fast cheap Bluetooth for my shop. If you overload it, it turns off and you have to wait a few seconds before it starts playing again. Just keep the output power at an average level and you'll be fine.

I didn't buy it for music. I bought it to play sound at 10kHz. Why? Do not ask! Anyway, if you want to play single or stereo sounds, I wouldn't recommend this device. It goes into the cutoff with almost no turning of the volume control. This means the security features are likely to work, and that might be fine for plug-in music or Bluetooth, both of which work.

I am very impressed with this product. Easy connection to a Bluetooth-enabled device. I plan to use it in my room as a projector with a pair of 150W wall mounted speakers. All of this will go to the headboard I'm building. I already checked for audio lag and it went away. Nothing will change my opinion of this device. Indeed this is a fantastic buy for the price. It's in the range where it should be and it definitely works for me!
