[QUOTE="Jörgen Raja, post: 8669222, member: 676599"] hello. I dont know if this is the right place but maybe somebody can help me. I have GAS pro 1000D amplifier. it was working perfectly for few hours, then subs started to freak out and amplifiers red "over current protection" light is flashing. I opened it up and one irfb4410 power mosfet heats up VERY MUCH. Also when when amplifier is powered up, it starts up fine, then goes to protection mode, then out of protection, and few seccond and back to protection. and it continues doing this. also at the same time subs freak out. So something is clearly broken, anybody ready to help me figure it out what is broken? I replaced the power mosfet but still same thing. So problem is somewhere else. There is nothing visible broken or burned, and nothing else heats up. Ideas what to measure what to look for? [/QUOTE]
