Audio Systems: 12v+ in line fuse?, mitsu eclipse, fuse panels

Question
i am helping a friend install an aftermarket cd player in his 2000 Mitsu Eclipse. while testing the deck i think my 12v constant and acc remote wires touched and now neither of them give power. also his car alarm receiver, dome light, and sunroof don't work now. I'm guessing theres a fuse that im missing somewhere maybe in-line? any tips would be greatly appreciated!!

Answer
This is why the number one rule was put into place - - disconnect one terminal of the battery when you do ANY electrical work. Make this same connection the VERY LAST connection performed.

Look in the owners manual for the placement of all fuse panels and start checking fuses.
