Sounds really nice. Fairly loud. Only issues is it don't have a real ground, the left and right channel are not full range even if you flip the switch. More like High and Mid. All lower frequency is through the woofer. I recommend getting the 300W Digital Amplifier Speaker Protection Board 2.1 Channel Relay on Banggood. This solves the popping issue when turning it on. The 150 inductors get warm. I personally will add heatsinks on them. The caps should be replaced. They are sketchy. My board came dirty. This looks different from what you see in the photos. Besides that, WORTH IT! Almost forgot. I am using the AC-DC Switchibg Power Supply Module AC 100-240V to DC 24v 9A Power Supply Board. Works fine but it's got a buzz issue.
