So commuting in Tucson (recently ranked 15th on worst cities to drive in) on a motorcycle, even with my conservative riding, I have to use the horn from time to time.  The stock horn wasn't cutting it.  It worked as it should, but was a very meager 'meep'.  :P

I picked up a set of these after seeing some videos on Youtube about them.  I found them on sale for $7.99 at Harbor Freight.
 


The wiring was pretty straight forward, the relay mounted right to a mounting bolt in the left side toolbox.  I used a 10A in-line fuse for the direct power.



Painted the brackets black to make them less noticeable.  Not sure I'm crazy about the mounting location I chose.  I wanted to go either high or low, I didn't want to obstruct air flow over the iron barrel.



And the finished product...



Not too bad from a distance...



And of course a video:  https://www.youtube.com/watch?v=5OcAgZSacf8

The sound comparison starts about 45 seconds in.  It is a huge difference, I mean huge!  In fact, I'm holding the camera when my son hits the new horn for the recording and it startled me even though I was expecting it.  Cagers will be looking for a Cadillac when they hear these horns...  8)

I always hesitated on those bc I didn't think they'd look good, but that looks great!

I guess I'll have to make a trip to my local Harbor Freight tomorrow. :)

I think they'd look great on a UCE, I have that big starter hump down low and up front, if it wasn't there, that's where I would have mounted them...

I looked at those last weekend but left them on the shelf.  I'll be going back.  Thanks for the video.

I bought a pair of them for about $10 but after getting home and studying the situation on my G5 an obvious place to mount them wasn't obvious.

I'm still studying things.
I'm not really in a big hurry.  I think in 3 years of ownership I've honked my bikes horn about 3 times.
It would have been 4 times but I use the thing so little, when I wanted to honk at the guy ahead of me for not moving on the green left turn arrow I poked the turn signal button.

If I didn't have an early ES model with the hump in the front, I would have used a Ubolt and mounted them low on the front, I've seen other models with the horns located there...

      The stock AVL's horn doesn't doesn't have a relay in its circuit, does it?  If it does, it's pretty well hidden.

       How does just a single horn sound, Azcatfan?

       I moved my horn during the first year. I never use it. It's too embarrassing   :-[  I don't want anyone to hear it IF they could hear it.

I did a quick test when I was hooking these up.  Neither the high nor low tone would sound right without the relay or without going directly to the battery.  So even running a single of these you'd still need a relay, which wasn't terribly difficult.

As for how a single actually sounds, either of these running by themselves is an upgrade to the stock horn, and of the two the high pitched one is more penetrating on its own.

             I ordered a set of these yesterday & I'll wire them both up with a relay & fuse. I have to think out my wiring well because I spent a lot of hours cleaning up all the wiring under the seat & unwrapping all the wires going forward (30), cleaned everything up & rewrapped the whole thing using '50s style cloth harness wrap.

              Did you plug your bike's original hot horn wire into 86 on the relay & mount it up forward? Then run a new 12V+ wire from the battery forward to the relay's 30/51 input?

               Or did you mount the relay under the seat? I guess under the seat is best

I used the stock horn wires to go into the relay.  Once I unwound the harness, the stock wires reached and allowed me to hook up the relay in the left side triangle tool box next to the main fuse.  Then I ran the wires out of the relay back up front and into the horns.  I used a bullet splitter and bullet connectors under the tank.

I'm at work right now, but I can take some pictures when I get home.

            I can see what you did in my head. I just don't really want to unharness that harness again. I spent Sooo much time on it before.

             I think I'll remove the tank, find a safe place for the relay up forward & plug the OE hot horn wire into it. Then run a NEW fused wire from the relay back to the battery. Then arrange it all well, Ty-Wrap it to the harness, finish the wires from the relay to the horns & I'm in shitcity with a set of 100db horns. Can't wait to blow them at some idiot  :) ;)
