hey guys. my pathfinder is a 2001 with bose audio, factory navigation, and an aftermarket kenwood deck with a sub/amp setup. my problem is the audio fuse intermittently goes out sometimes within an hour of putting a new in it and sometyimes it takes a week or two. ive had this problem since i got the car a few months ago. anyone else run into an issue like this? i pulled it all apart; no touching wires i can see and the nav unit is a remanufactured unit so perhaps its in that? also the problem has been occuring since before i put the amp/sub in. i should also note ive used higher amperage fuses (up to a 20 amp) and even a paperclip to try and sort out the issue but unfortunately not even a paperclip could resist and ultimately burned up. all help/ideas/thoughts is appreciated.
