a noob question

I just picked up a memphis 4 gauge wiring kit from one of my local shops, and it came with a 150 amp ANL inline fuse for the battery to amp hookup...what exactly does the fuse do?

If a problem arises, hopefully that fuse will blow before your amp.

No, the fuse protects the wire from overheating and burning down the car.

On board fuses will protect the amp (or if a manufacturer does not include on board fuses, then one must be placed at the specified rating as close to the amp as possible)

Yup also protects yours cars electrical if you happen to short out the power, this way the inline fuse will blow instead of all the other fuses in your car lol

No, current travels in the path of least resistance. A dead short is 0 resistance and therefore will only travel through the shorted wire. Electricity doesn't just travel throughout all the circuits.
