I had my first (2) Stebels mounted like that. They don't like water as they have steel diaphragms. Once they start to rust they stop working. Always covered them when washing but not real easy to do if you get caught in the rain.
Luckily I'm in So California and took the option to give up rain riding. On the rare need for a full soap and water bath I throw a plastic bag over it.
The Stebel will work without a relay but occasionally will sound like a duck. The more you use it that way the worse it gets. Put a relay in and you double the volume - every time.

Yes, but it is still not advisable to pump that much electricity through the normal harness, in my opinion. The Rockets already have issues with "melting keyswitches" that have driven people to get relay kits for their headlights, and a headlight doesn't suck down 20 amps, they're 5-ish for a 55 watt bulb. Granted, a horn is used briefly and rarely but even so.
