If you have an Infinity system, check the fuse for the remote amplifier. I assume you checked the cd and / or cassette player for sound too. Depending on the model of your radio, it can be dead including no display. Holler back with a physical description of your radio. I've repaired a lot of Chrysler radios.
Also check for inoperative interior lights, lighter, and horn. One of these circuits will power the radio's memory circuit. Some radio models will appear to work normally but have no sound if the memory fuse is blown. The clue is the clock will reset to 12:00 each time you turn on the ignition switch.
