You can really take the loud horn thing to far. If you want a super loud horn and dont want to mess with 6 volt 12 volt problems. Use an air horn from semi-truck. You will need a compressor of some sorts to drive it,but it will blast like a mutha. Even better yet,get a air horn from a train. Maybe even one of those horns off a cruise ship. Now that'l get everyones attention
