Recently my amp dropped into protection mode and im unsure as to why. the amp is a Kicker 4channel which is fairly new. It is running 1 1000w 12inch sub and 2 6x9 speakers. I did the basics first, i checked the ground wire and sanded back and cleaned the contacts. I had the battery charged to full amp to make sure it had enough power. the bettery and amp fusses are intact. I also get the whizzing alternator noise with the amp in protection mode! im running out of ideas as to what it could be ! All the wiring is the correct lengths and guages.
Any help would be greatly appreciated!
