Well I valet my car at the Mall today, when I got it back the stereo was dead, drove it home and checked the fuse it was blown. I have not yet replaced it so not sure if it was a short or just an overload or random occurence. What I am thinking is that the fuse for the stock stereo may not be sufficient to power my current head unit, it is a 10A fuse, assuming it does not short out when I replace it would you guys recommend perhaps putting a 15A fuse there instead?
