Review on 🔊 DAMGOO Bluetooth Amplifier Board: 100W+100W Peak Output Power, 2.0 Channel DC:8-24V, Password-Free Connect, BT 5.0 AMP Board for DIY Wireless Speakers by Tom Motko

At the time of writing this tiny $$ device has a very big and very good sound. However, if you want to use its full potential, you will need a fairly large power supply. I suggest 9.5 amp 19 volts or more, say 10 amp 24 volt supply. I use a 9.5 amp amp and it works great with my 120 watt speakers. UPDATE: Right channel no longer works. No idea why, but was immediately replaced by the supplier. Let's see how long it takes for the new one to fall off. Yes, I test speakers with it, that's the whole point. It says 4 - 8 ohms and I'm torturing the speakers with that. Apparently, this device also tormented.
