Decided to go back and revisit the horn installation. Went to the local auto parts store, and bought a Standard HR117 Horn Relay...
I mounted the relay on the "neck" of the frame directly above the horn bracket after painting the relay and all associated parts black to match the frame. The relay is mounted downward so as not to allow water to collect in the electrical components.
Next, using the bracket supplied in the FIAMM Freeway Blaster horn, I attached one end of it to teh OEM bracket, and then angled it back inward toward the front of the engine and tucked it under the gas tank as much as possible. With the horn mounted it doesn't protrude as much and isn't quite as noticeable.
I also painted the entire horn black, as the rear side was plain metal so it would blend in better with the bike.
The addition of the relay made all the difference in the world with regard to sound quality of the horn. Before it sounded anemic, but afterward, it is much more robust.
I used 14 gauge wiring coming off the relay and into the horn as well. I'll try to snap a few pics of it maybe later on today and post up here showing the installation/mounting.
It's nice to sound like a Buick as opposed to a scooter!!!
