Review on 🔊 DAMGOO 50W+50W+100W 2.1 Channel Subwoofer Amplifier Board with Treble and Bass Control, Dual TPA3116 Chip, 12-24V DC Input, Bluetooth and AUX Inputs, DIY Wireless Speakers AMP Board, Password-Free by Randy Olson

Another update. I got it working but for some reason I had to plug it in twice as the device showed up as two different devices. I had to do it on two different computers. At first I thought it was the first PC. Now it works perfectly, with equalizer it sounds good, without it is very muddy. I use Equalizer APO (PEACE as frontend) to fix audio. It sounds good. I needed an output stage for a modular synth setup. Nothing special. Paired with an 8-inch subwoofer and decent bookshelf speakers, it just sounds great and exceeds my expectations (almost never very high on Amz stuff). It is very compact and installed under the shelf. I'm using line-in, not BT, so can't comment on that. It would be easy to panel mount this amp, by the way. Add input/output jacks and a homemade VU LED. Moog style. It's legitimate. I just ordered another one of these PC Media units to replace a similar cheap Class D amp, also BT and 2.1, but it doesn't smack well and the volume control is already scratchy. Hope this product last longer.
