i have a lightning audio amp, it was wokring a few months ago when i pulled it out of my car, i tried yesterday to see if it worked, it turned one for 5 seconds and went into protection mode, so i tested it with the battery and it did the same, and the cables got hot, and help please
yeah you probably need bigger hots and grounds your wires should never get hot
Having the alarm put in should not affect your amp, I hate taking my car somewhere thinking someone might play with, and maybe break my toys. But yes they were right always sand the ground spot till its nice and shiny but I cant see a week ground tripping the protection light. Try unhooking the power wire and run a temperary one from the amp to the battery to see if your power wire might be the culprit by wearing and posibly lightly shorting against metal. The power wire is the most likely to be the guilty party if everything bench tested good (also relace the fuse at the battery they can become defective without breaking I had that happen before) Good luck.
you need bigger cables i think, as they heat up resistance gets higher, so the amp would not be getting enough power
