I bought an industrial, 12 volt, 7 amp horn, off that auction site we all know and love. Planning on putting it in the 51 Chevrolet Business Coupe, and just subs***ute it for one of the existing horns. Workable this way or should it have it's own circuit? It's about 2 feet long, so mounting is going to be the real problem. And, it is LOUD! Butch/56sedandelivery.
