The Ford Barn - View Single Post - Horn sounds bad on 12 volts

A 6 volt Ford horn working on 12 volts requires a wire wound .5 ohm 50 watt resistor in the power feed to each horn. You can buy these on line pretty cheap. The resistor can be fitted under the dome cover of each horn and then cant be seen. The 50 watt rating is required to handle the horns current draw so don't opt for a lower rating. Regards, Kevin.
