I ran it with a 12V 3A power supply, the amp had a thud when plugged into the Mi Box S when it was off and the bass channel suddenly stopped working. There is no cutoff frequency setting, but the power rating (in combination with the correct power supply) is as advertised. I would recommend using it with a passive crossover and matching the switch to the power supply.
