Review on 🔊 High-Power Digital 2.1 Channel Amplifier Board with Bluetooth, USB, and T-F Input - 50w x2 + Subwoofer BTL 100w - Ideal for Home Stereo Speakers - DC 12V-26V by Molly Richards

the first one I bought worked very well it sounds very clear and gets quite loud it has a woman on it which says Bluetooth is ready every time you turn it on, although I could do without that. The second doesn't work at all. As soon as you turn it on, it makes a hiss and the sound is distorted. The subwoofer channel is not powered. However, Revain refunded me for the product. All in all I would recommend them, they sound very good, have a nice thick record and seem very well made.
