Because that's the most reliable power source. What is best for the radio
"power wise" isn't necessarily what's best for it (or the supply lead) if
the connection from the battery to the chassis or frame goes bad...
especially when you try to start the engine and the negative lead from your
radio tries to pass a couple of hundred amps through it. With the negative
lead fused, it will blow the fuse and protect the wire. Without it, you
would be looking at a meltdown situation.
