okay.. i just installed a boss chaos c450 amp 2 channel 4 ohm and it worked for a day. We were bumping it and after the end of the night, it just cut off. i checked to see what was wrong and the 25 fuse had blown.. replaced it and tryied it again and the protection led only turns on for like a second and then nothing happens.. green light wont work nothing.. checked the inline fuse in the battery and it's fine. checked ground and blue hu wire to the amp, fine. what else could be wrong.. alll the sudden it was working, and then all the sudden it doesn't work.. did i fry the amp? what would cause it to fry so bad.. thought the fuse in the amp was for that reason. any help greatly appreciated.
