Review on 🔊 High-Performance 2.1 Channels Bluetooth 5.0 Subwoofer Class D Amplifier/Receiver: 50W+50W+100W, Adjustable Bass Frequency, DC 12-24V by Frank Chinchilla

These little amps offer amazing value for money. You sound great! There are many versions with different combinations of features. I recommend getting one that also has a line-in, although the Bluetooth quality is very good. My favorite model has a top volume control and a separate switch. For some reason, those that don't have a dedicated power button leave Bluetooth on while connected, even if the power button is off. This is a minor annoyance. All in all a great little amp project. Vendors should provide project boxes for them - I would buy one rather than make one, but you can use it as is.
