the radio should just be powered from a switched and live 12v source? can fluctuate obviously..

should there still be 12v when the ignition key is at the 0 mark? i just get next to no voltage from any wires when the key is in the 0 position

You can get a constant 12v feed even when there's no key in the ignition. A radio will need one of these constant feeds to keep the memory for stations etc. And it will also require a 'switched 12v' so something that only comes on when the key is turned.
