Review on 🎧 Protective Headphone Bluetooth Amplifier by DAMGOO by Justin Ferguson

Just hooked up to my homemade speaker box which runs on 12 volts and 2 amps. The overall connectivity options on this board are really great! Two audio inputs! BT and AUX cable, two power inputs, DC jack or power jack with standard screw terminals. Only these two things are hard to find on the board, and even more so in this price range. SOUND QUALITY: Generally acceptable. Obvious noise at high and low levels. You can only hear it when you are very close to the device. I'll know if it's my PSU or something when I upgrade. I've checked all my connections and it doesn't look like it's a loose wire. POWER: I'll try 19 volts and 24 volts and see if I get more sound. At 12 volts it doesn't feel like 50 watts x2. I have another BT board with the same volume, so I was expecting more power/volume from this higher rated BT amp.
