The amplifier comes with a 32v/5a power supply (160w) yet you claim a max power output of 300w; how do you produce more power out than is supplied?

Someone answered here saying you can run a 48V power supply for more output. Well yes you will get more output OF SMOKE! These units cannot withstand 48V power supply as the capacitors are only rated for 35V max and 35V max is clearly marked on the amplifier! I measured 20V RMS clean sine wave driving a 2ohm load - that is about 200 watts RMS continuous... when they say 300 watts, that is some peak (instantaneous) rating but not continuous. I got that measurement running the amp with the included 32V power supply.

Supongo que hay varias maneras.. en mi caso lo hice desde la salida subwoofer preout de mi Amplificador (canal .1) al audio in del aparato. Luego las salidas deben ir conectadas con los cables del subwoofer que me quedaron cuando retire del parlante el amplificador dañado

Do i need a crossover for the passive subwoofer if i connect it to amp’s speaker output? is the sub cutoff of amp only pertains to sub output only?

The low pass cross over knob only works for the speaker high level output and does not control the low level sub out
