OK...I am back in Nebraska and was having trouble with my bro's car in Minnesota before I left. Anyway, he tore it apart and found that there was no power from the battery to the amp. Everything LOOKS fine in the run, but the power is good before the fuse and is not running thru it. The fuse does not look blown, but can it still be? Or is it more likely a bad fuse holder? Thanks, I appreciate it!
