I have bought this board but when removing the heatsink it appeared to use a different chip the tpa3255. The problem I am having is it shuts down sometimes. I am using a 36 volts lithium ion battery and a 4 ohm woofer. But at max volume and bass heavy parts in the music it pops and stops working. It still drains the battery and the indicator light is still on but no sound is coming out. When turning it off and on again it continous to work. Does anyone know what the problem is. I suspect it is the overcurrent protector. But cant know for sure and what I should do to help it.
