I used the oil cooler rock guard and re-enforced the aluminum with a galvanized steel strip.
The 12vdc Relay sits where the original horn sat. I ran a 12g copper wire directly from the bus bar under the seat that ties directly to the positive side of the battery. It feeds both legs of the relay. I installed an inline 15A fuse under the seat to allow easy access if it blows. The horns are properly grounded as is the relay. The relay is STDP so I used one leg for each horn. The relay is tripped by the power directed to the original horn with the original horn button. Just one more way to skin this cat. They sound like a small truck ! In traffic they are like a American Express card, PRICELESS ... I’m very satisfied.
ADDENDUM At the suggestion of of a fellow 9Ter I aimed the horn opening down. Bugs !

Man, you lost me. You are at another level of skills. Good for you. My only concern with such a loud horn is if it would be taken as road rage by others, and hence increasing a different risk. Of others doing something stupid out of behing hot headed. I saw some leave the stock on and seens to be the only one it works in a dash beep. Safe riding.

I’m tend to think that a horns positive or negative impact is somewhat dependent on how it is used. The frequency of use, the duration of noise, ...how you honk, has a great deal to do with how it’s interpreted. If you watch to see if the intended recipient reacts ..which is a good indication that they heard you and at that moment stop honking, most time there’s no harm done and you don’t get run over. Of course if you stand on you horn even when it’s obvious they heard you.. then you can expect a negative reaction. In my experience, its all in the honk and not the volume. Volume only assures you they heard you the first time you honked and not the second or third time after they’ve almost run you over. Using your horn defensively instead of offensively has an enormous effect on how it is taken an thus acted upon. Be courteous not corrosive. StayAliveUpOn2 my friend. I have an enormous amount of power available to me on this moto that I sometimes use fully ... I want the same option with my horn, great potential and power used with intelligence not belligerence will go a long way. It keeps me alive an well in traffic UpOn2 ... what more can I ask.

Great info, I'm in the same camp. I want something thats easy to fit and isn't the embarrassing chirp of the oem horn.

I think, (and that usually gets me in trouble) ...the difference in the sound of a bike horn and an automobile or truck horn is obvious. I don’t know of any bikes with factory two-tone horns but almost all 4 wheeled vehicles have dual tones .. when I have the occasion to honk at auto’s in traffic (Because I have two-tone horns) ...they automatically think I’m a car or truck because of my horns ...I seem to get a much stronger and quicker response ... so I say ..do the upgrade Definitely, but go for the harmony in two tone units. Gives you more respect when people think it’s a truck and not a scooter ... beep beep !! ......Blitz

My SoundBomb mini had been sitting on the garage shelf for a good few weeks, so decided to lift the petrol tank and fit it this weekend. The weather was suitably rubbish that working inside the garage seemed to be the best option.

I chose the Mini along with the CanBus connector as I was hoping it would be a straight swap with the original and mount in the same location hidden under the tank.

Unfortunately there is no way the SoundBomb Mini will fit in the same location as the original horn on my Urban GS, I cut the cable ties of all the cables in the vicinity of the horn so they could be moved out of the way, I also bent the mounting bracket as far as it would allow but there is no way the Mini will fit.

In the end I replaced the original horn while I consider if mount the mini in a different location or go for the full size SoundBomb considering i need to mount it in a different location anyway.

On a positive note the petrol tank was easier to remove than I was expecting, I guess I had been preparing for the worst. And it seemed like a good idea to replace the air filter while I had easy access. So not a completely wasted afternoon.

When I removed the original horn from Blitz (2015 Classic) Hack, I used the space to hold a simple automobile stock 12vdc horn relay to which I attached the original hot wire from the horn button so when I hit the horn button the relay clicks and closes contacts as long as I’m holding down the button. Then I ran a heavy gage insulated copper wire with an inline 20amp fuse (under the seat so its easy to change if needed) directly from the battery to the new auto relay, from there I split it into two wires of the same heavy gage one to each side of the oil cooler and mounted my dual horns. They are sooo loud... I love it. Saved my butt in traffic more times than I can count. In traffic I use my horns and flash my high beams dozens of times every time I ride (Very short beeps and flashes) every time I see a vehicle that I even remotely think has not seen me. I know it works, I’ve seen them Stop abruptly when they were going to turn casually right in front of me. People aren’t looking for bikes ....
Loud pipes, loud horns, flashing lights ..... Hell.. Wave your arms if that helps .. BE Seen !
Don’t get dead or injured thinking they’ll drive like you would and be paying attention ..
You Get Attention ! .....StayUpOn2 Take an active and aggressive part in your safety, there are way to many pre-occupied stupid four-wheeled nimrod drivers ...... BeWell .....Blitz
P.S. I also have a shelf where parts are sitting, ..I’m thinking about moving that relay to a new place to make room for a Gorilla Thieft Alarm with remote a pager .... this bike has NO space to add anything ... She’s beautiful ..... but ✌😎 Enjoyed your posts Hack ... stay at it Mate.

My Enfield Continental 535 had a two-tone horn--and I agree with you completely that it makes a difference because of cagers' perception that it's another car.

Take a moment and glance at the thread “My Exhaust Pipe and Bobber Build” entry #125 about dual air horns that work … no no, I mean actually WORK. If you want horns so someone will hear you …this is from my experience the best yet. Actual “AIR” horns .. not electric horns. Small motor compressor, hoses, trumpets etc …. My complaint in the past about such a set up was … unless you mount the compressor close to the horns .. there was a delay from when you hit the horn button and actually got “Honk” out of the trumpet … it was actually the half-second time it took to pressurize the rubber hose feeding the horns, it was about 4’ long. I hated the response time …soooooo on this install (I’ve done this on 4 different bikes now) this time I made up all the feed lines between the compressor and horns in copper tubing. Now it’s close to instant in its response. Check out the thread … I need to get a DB meter and get a value because ITS LOUD ! Really loud. I’ve never had to do anything but toot it, never needed a full on honk, …and it’s sound is SO not motorcycle, more like small truck ……………. Blitz
