The radio should be power by one of the accessory circuits not a "12v" circuit used by the appliances.  On my converter there are about 6 or so separately fused 12v circuits and the last three are the accessory circuits.

The 12v circuits are disconnected from the battery when plugged in to AC and are powered by a full wave rectified AC current.  This is not filtered.  The accessory circuits always have the battery in the circuit to filter out the AC hum.  You can find the accessory power at your cigarette lighter plug since this is close to your stereo.  It should be fused with a 15 amp circuit.
