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 Samantha Hervey

After all, what you pay for is what you get. I have an old SONY two speaker system (early 2000's) and I tried different bass and treble levels to adjust the volume and the output was really smooth (no voice breaks). Its 20 watts per speaker and the sound is pretty good. Someone who is really on a budget and doesn't want to spend too much money can definitely grab this device. Another beauty of this product is that it comes with an adapter. I highly recommend this product.
