I bet the first question will be "why the heck would you want to do that??"

Well, my car is going to be in a car show. It's indoors and the rules state that we must disconnnect the car battery. So, I need to run my car stereo, LCD and computer without the car battery. My computer and LCD is taken care of. I can plug my computer into an AC outlet. The LCD I can plug into the ATX power supply. I tried that once, so it shouldn't be a problem. Now, can I do the same with the car stereo? I was thinking of running a wire from one of the power supply leads (red wire, of course) into the fuse for the car stereo and then grounding the black wire off the power supply lead. Is this going to work? Or am I going to fry something?
