All depends on whether the plug going into the Sirius is at 12 volts or 120 volts. I have no idea. It takes about 32 volts for current to flow through your body, so a 12 volt wire under no circumstances can hurt you. If the body of the Sirius is non-conductive, again unless you put a wire into it while standing in water on a concrete floor, you again will be beyond danger. If it is 120 volts presented to the Sirius, it has a metal body, you are grounded, and somehow the case is charged at 120 volts, you could be in danger. Incidentally, if you use a cheater plug and ground it grounding wire to the outlet, your circuit breaker would immediately open in the event of a charged body of the Sirius.
Rex strikes me a unduly concerned about the grounding wire to components. Underwriters Labs insists on grounded components with metal bodies, but few major manufacturers of front end audio components bother to ground their chasses, because of the ground loop problem thus introduced.
