Yes, the body of the car will be positive, the body of the radio negative.
If they ever touch, you got a short.
All you have to do is insulate the radio from the car with wood, plastic,
etc. I am not sure if the antenna must be insulated also (I think the
coax shield connects radio and antenna), I did.
I mounted a piece of plywood to the underside of the....uhm...top of the
footwell, then mounted the radio to bottom of the wood. Don't let any
screws go through the wood. The radio is out of sight and doesn't spoil
the look of the interior.
