There's not much you can do yourself to cure this the only thing we can do is try a complete system reset . Disconnect the battery touch the two battery cables together for 30 seconds this will completely discharge and reset all the modules in the vehicle after that reattach the battery and see if the problem still persists if it does you'll have to either remove the radio and send it out for repair or people vehicle to the dealer and drop it off for repair
The radio and the amplifier are both said it was with these two fuses, tell me if you have power on both of these fuses
