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 Sarah Felder

I work in a store and use a $50 Bluetooth speaker for music, which was fine at best. I have old speakers that are collecting dust and I decided to build a small boom box. Well it's a BOOM box. This amp is great, has enough power (19V, 3.3A, laptop PSU powers it) and looks pretty cool. The sound is clear, there are basic EQ settings for the full-range outputs, and bass and subwoofer volume levels. Connects quickly and easily via Bluetooth. If you have an old subwoofer and a pair of satellite speakers, these will bring them to life! I'm honestly shocked that this 10" subwoofer moves so much.
