If it is Analog (not digital) there is only "one" Power wire.If there is no sound, then test outputs at the back of the Radio with a Test SpeakerMany times the CB Box will cause the no sound, because it mutes the RadioThe Antenna has 2 power wires12 Volts + from the Radio when On12 Volts + Constant ORANGE wire (should be CIG Fuse)Check voltage at the Power Antenna with the Key On
