dual runs fused?

[yogegoy]

No one bothered to mention why it's necessary to fuse hot wires. The main reason for fusing positive side of your electrical storage is for your safety when you get into an accident, where the positive side somehow contacts the negative (grounded to your chassis) causing a short that eventually end in a fire. A battery cable will heat up melting every insulation of most of the wires while still conducting electricity. As long as the positive is connected to it's source it's almost impossible putting a vehicle fire out unless it is submerge in non flammable liquid. Ever wonder why a burning car's horn is activated? It's because the burnt wires are still conducting electricity specially unfused main cables. So the fuse isn't there to protect your sound system, it's to protect you if ever you get pinned in the car and your main is shorting out, it disconnects the power side up to where the blown fuse is located. That's the reason I carry a cable cutter and welding gloves inside the vehicle.
