I think I need a resistor in line with my horn to lower its volume. I am trying a two way system with a 2446J as the top end and a 3110A crossover. I turn the volume nob on the crossover to its lowest setting and the horn is still to loud.

I would like to turn down the horn volume approximately 6db. Should I put a resistor in line? What value, What type, Where to insert it and Where to buy it would help me.

Thanks.
