Review on 🔊 WSDMAVIS Subwoofer Amplifier Board with Bluetooth 5.0 and Wireless Speaker Integration: ZK-TB21 – 2.1 Channel Audio, AUX Inputs, 1 Pcs AMP Board by Bill Martinson

this thing can give some juice! I powered an inexpensive 12" subwoofer I bought at Walmart with this little amp and it did the job perfectly. become loud! I tested it with some tweeters and 5" midrange drivers and it worked great. The clarity is unreal, no static or annoying hum coming out of the amp when I paused the music, even with the volume cranked all the way up. This is one of those purchases where you can't believe the value compared to the actual price of the product. TO BUY! You can't go wrong with this device. I enjoyed it and enjoyed playing around with it.
