Idiot-proof or not, it sounds miswired. If it's a GM vehicle, then you probably have a speaker wire connected to the vehicle's speed sense wire. Many GM's (and probably some other makes) have a feature called Speed Controlled Volume, which when activated turns the radio up as you go faster. To do this, there's a wire in the radio harness that's tied into the speedometer circuit. It's usually a green wire, so it's the same color as the factory right front speaker wire; when the radio turns on, if it sends voltage to this wire it will kill the speedometer.
