10 reviews for ZK-MT21 2x50W+100W 2.1 Channel Subwoofer Digital Power Amplifier Board AUX 12V 24V Audio Stereo Bluetooth 5.0 Bass Amp for Home

  1. Carla Poole

    Some tips for those who doubt whether it works only with 2 speakers and the sub. It doesn’t work only with 2 boxes, it works with more boxes, but just be careful with the maximum impedance of the device that is 8ohms, just make the correct connection, because if you make a wrong connection you can overload the device to burn. Device is great for the benefit cost. I used 4 home theater boxes
    4ohms each + 1 8ohms sub, the 4 boxes (connected in series with my configuration). I used a 19V-3.4a notebook source. Buy without fear, clean sound and very powerful for size.

    Excellent product. A lot of quality for the size and price. I’m sorry I couldn’t find a 5.1-channel family member. Would buy on the spot
