Where in the world are you? Is the vehicle an R 129? US market vehicle?
short in a wire is my guess. When you pull the head unit I would look for the power wire with the insulation broken

In a stock audio system fuse C powers the amplifier located in the right footwell (picture). I'd unplug the amp and see if the fuse still blows. If it doesn't, then the amp is suspect.
