Have not yet changed anything on a Spyder yet, but have upgraded the horns on more than one 2-wheeled motorcycle.
Even the stock twin "beep-beep" horns weren't good enough, so I went to Auto Zone and got a couple horns. These were horns that look much like Motorcycledave's Cadillac horns, not the flat type. Be sure to get a "high" and a "low" horn, they are about $15 each. A relay will ensure they get full power.
