I tested this Bluetooth amplifier board on two 60W Denon speakers with a 12V supply voltage! For it should be noted that the indicated performance data can only be achieved under ideal conditions (e.g., high input voltage). However, the performance of this amp convinced me even at 12 volts, and it is a nice toy if you want to connect your phone easily to your speakers. Of course, you should not expect any miracles with a ~$12 amplifier board (for a party in the garden, it should already be enough).
