After my car sits for a while (more than 10 minutes) my aftermarket Kenwood CD player along with my cigarette lighter, resets. I verified that the yellow wire from the radio was connected to " constant power" (yellow wire). I switched the " red" and the " yellow" just in case the factory coloring scheme was backwards, this did not work, I switched the wiring scheme back. I checked the fuses, it is the right size fuse and they are all working. The car battery doesnt reset, just the radio and cigarette lighter.
