i was changing the deck in my car and all of a sudden it turned off, its not the deck because i tried a different head unit and it didnt work also. i checked the fuse and its good and i also did some sort of reset my friend told me to do where i disconnected the battery but that didnt work. it is very possible that some of the cords touched because i was just testing it out and didnt have the cords completely covered. if anyone has any insight on what i could have done it would be much appreciated.
