Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.
Check each set of wires and speakers to be sure no wire or lead is connected to a chassis ground. The radio will see this as a short and turn off the internal amplifier causing the on but no sound issue. Each speaker connected to the radio needs dedicated positive and negative leads from the radio to each speaker.
Turn your car on, but do not start the engine. Turn the radio off. Hold the radio power button down for a few minutes until it resets.
