I will differ with Fred - the fuse should be mounted close to the power 
supply - you are protecting the wire, and not the radio..  There could 
be a fault in the wire (actually more likely than a fault in the radio), 
and a fuse at the power supply end will trip - think about a fuse at the 
radio end and a short in the wire near the mid-point - the wire itself 
may act as the fuse unless the power supply shuts down due to 
overcurrent protection first.
