Review on 🔊 Facmogu ST-838 40W Mini Digital Hi-Fi Power Amplifier with 2x20W, 2.1CH Subwoofer Amp for Enhanced Stereo Bass, Audio Player with 12V 3A Power Adapter, Amplifier System for CD MP3 MP4 PC Car Home Speaker by Becky Williams

The fit and finish of the device make it look cheap which is a shame as it's really decent for the money. If you play around with it a lot, you can use sandpaper or sandpaper to go over all the edges. It's not high-quality sound, but it's decent for a small, less-powered amp. I use it as a subwoofer amp to drive a Dayton transducer for vibroacoustic therapy. That's enough to drive the converter as far as I'd like, and having separate volume controls for the subwoofer and regular outputs is ideal. If they used standard speaker terminals for both the sub and main speakers that would be nice as the screw terminals for the sub are a bit odd. Overall not bad for the price.
