Blown Audio Amp Fuse

[andrewellis91]

Hey Guys,

I'm having a problem with my 2002 Infiniti QX4. I started my car the other day and the aftermarket pioneer head unit I have installed din't come on. When I got home I checked the fuse box and sure enough the fuse labeled "B 15A Audio Amp" was blown. I took it out and replaced it but the new fuse sparked and blew as soon as I plugged it in, even with the key not in the ignition. I then opened up my dash and unplugged the head unit from the car and tried replacing the fuse again but the exact same thing happened. Anyone experience a similar problem or know what other things are on the same fuse so I can try to track down the short. I installed the new head unit back in December and haven't had a problem since.

I would pull the radio and inspect the wire harness, make sure no wires are exposed
