ARRAROWN Amplifiers Editorial Review
The ZK-1002T Bluetooth 5.0 Amplifier Board 2.1 200W is a versatile audio amplifier module for DIY speakers. It comes with BT and AUX inputs, treble and bass controls, and supports bridging. Users can connect subwoofers, center channel speakers to the subwoofer output, and use 24V 8A adapter or a 20V Dewalt lithium-ion battery to power it up. According to customer reviews, the audio amplifier module provided high-quality sound, was easy to assemble and tune, and worked well with Bluetooth and wired audio sources. However, some customers faced hiccups while connecting to Bluetooth devices, and the Bluetooth occasionally connected to random devices, cuts off sounds when the volume is loud, and had no input other than Bluetooth.
