I had an occaision to use my horn today when I had to avoid hitting a lady in a pickup failing to yeild the right-of-way, to me. I noticed her looking over her shoulder (not in my direction) as if she was trying to figure out where the honking was coming from. I'm not sure if she ever saw me, even though it was only 5:30 pm and my headlights were on. I can't even really tell where the horn sound comes from. Sometimes it sounds like it's under the floorpan or in the trunk. Has anyone done a successful horn upgrade with another model horn or aftermarket model? I'm really disappointed with the stock horn, and will change it, I just thought I'd ask to see if anyone here has done this type of modification.
