Wired atx green with a black yellows together as12v blacks together for earth when I powered it up it wanted to go but tripped


You seem to have written pretty much everything in the thread's title and left the thread's body barren. You might want to swap that out. My question is why deal with an ATX PSU in a car when you have a battery in the car as well as access to resistors...? Make and model of the PSU as well as the Audio you're trying to install?
