hello, i have this car amplifier (lightning audio b2.300.4). the protection lect keep coming on. there was no voltage after the n-channel mosfets.when the pwm ic was removed the the amp was powered up,there was voltage after the mosfets but amp still not work.

what could be the problem to cause the ic to creat such a condition where the protection light comes on and the voltage being lost after the mosfets?

can anyone help me solve this problem?
