Can someone help me troubleshoot my Pioneer DEH-10MP car stereo. I installed it myself. I turned it on (I didn't turn the engine on) and everything seemed to be working fine. I turned my car off and finished the mounting and turned the car on (this time I started the engine) and this time no power to it at all. I checked the wires and the yellow and white wires came undone. I pulled it out and recrimped the two wires and tried to doe it all over again and still no power. I examined all the wires carefully and they are all connected and crimped perfectly. I don't know what else to do and I am extremely frustrated. Can someone help me?

If a wire came undone, and touched ground, you may have blown a fuse.
