I have a Honda Big Red two seater ATV, and I just installed a horn from an old Chevy Blazer on it yesterday. I don't know if it is because I used a small sized wire to hook it up, but it doesn't toot very loud. It sounds just about like a goose honking. I pulled up in the yard today, cut the motor off, and my 3 African goslings stuck out their necks and gave me a talking to. I "honked" the horn and those three dudes came running as fast as they could go and went right up under the ATV. I guess they think it is their big red mama.
