Defensive motorcycle riding sometimes is not enough. My Denali horn has saved me a few times now. Money well spent for sure. Just ordered another one for my new bike as the old one got traded in for a new bike. Five years with no issues. This sucker is LOUD!
It's a winner. Mounted one on my V-Strom 1050XT and it sounds more or less like a Mercedes. Gives you an equal footing on the street when car drivers get out of line.
Great video! One thing to mention is that, the Decibels scale is non linear, meaning, a 10db increment is different from where you measure that increment from. These things are loud!
I think the SoundBomb Original would be a good replacement in my Jeep Grand Cherokee. I'll definitely look in to it, because it will be close to twice as loud as what the Jeep came with for a horn..
Great Video! I have the Sound Bomb original on my 2021Yamaha Super Tenere mounted with the bike specific bracket. It is really LOUD alerting other motorists when needed!
I ride a Triumph Rocket GT 22 and I think the standard horn is pretty limp. I was going to buy the Danali Sound bomb mini, but the test in this video made the difference between it and a standard horn seem minor. Thank you for the vid none the less, because I learnt more about power requirements for different units, and that a power relay must be some sort of booster/amplifier.
@@andrewscarlett2225 I did end up with the Denali mini sound bomb. I installed it myself, but it's really squashed in, and the echo chamber should be facing out. Mines facing in. Sound is louder but not obnoxious, and there's a screw on the side that might make a difference. Safe riding.
Glad to hear how it sounds. I bought the sound bomb 1 piece for my 2021 street bob, it came with no instruction manual at all so now i can see how to wire it up. Would love to see how to mount it on my bike. I was thinking to put it right where the stock horn goes but been told the opening for the horn should not be dacing forward, so not sure where or how to mount it.

If you are struggling to find a home for your SoundBomb, give our customer service team a call and we might be able to walk you through it. A SoundBomb Split might be a more appropriate horn for your application. denalielectronics.com/pages/contact-us
I would love to see you create a dual "original" set up, tuned to work as 4 total tuned horns! Because if one Denali Soundbomb is awesome, two tuned to work together would be epic!
Denali, Fiamm or Hella, which is the loudest. I am looking for the loudest electric not AIR horn worth a separate compressor with tubing. Cadillac used to have a "5" electric horn set up. Tones A, B, D, F and a small like 9" trumpet. That was not quite like a train, but it was loud. I would like to keep my factory horns I have a 25 Silverado, and add something extra that really stands out.
You will love it! Be sure and check out our horn with cover kit too: denalielectronics.com/collections/soundbomb-horns/products/soundbomb%E2%84%A2-compact-horn-cover?variant=30468218191972
Great Video. You should create kits to purchase for the Challenger/Pursuit and for the 2020-current Chieftain Limited/Dark Horse. Would love to get that for my Chieftain. Also, I assume you used a Dialdim controller for the D4's? what mount is that as well? Another thing I would love to add to my Chieftain instead of buying Indian lights.
We will feature the Indian setup in a future video giving all of the details of the install. We used the DialDim with the D4s on our crash bar mount. Keep an eye out for that video in the coming weeks!
I would say the sound bomb original is the ideal horn for a John Deere 12 wheeled articulated tractor or any large ag tractor over the factory Hella disc horn because of the monstrous size of the big machine. It beats screaming any day.
Great demonstration! The driving lights on the Indian flashed when used that split. Is that a feature to help be seen? Or because the bike wasn't on and the extra draw on the battery?
I know your comment is old but it's due to the voltage drop from using the horn and having the lights turned on without the power source being charged. It's the same concept as when you have a 12in sub in your car and the lights dim when the really hard bass hits, there isn't enough juice so everything on that circuit is getting a little less than it optimally wants.
Please tell me which flat bracket you used to mount the compressor that's on your website for ordering? Also, so you have a bracket available for the horn section? I have a 2023 Indian Pursuit, which is set up just like the Challenger in this video.
For a 2017 Nissan Rogue Sport SV, what one would you recommend? I know I will need a relay and that would take the place of the existing horn so that it can allow power to the horn without overloading the vehicle's horn circuit. I can even tell that some low strength LocTite (the weakest one) would be helpful to keep any horn from vibrating off. Just make sure that it doesn't interfere with the ground of the horn or it might not work. It is like a glue or plastic.
Depending on where you mount it, the Original or Split would be a good choice. If you you have the room to mount it, the original is less complex and produces the same sound. We sell a harness to make installation a breeze: denalielectronics.com/collections/horn-wiring/products/dnl-elc-10000?variant=15068522741860
I am hoping a SoundBomb Mini will fit as a direct replacement on a 2022 H-D Pan America. I am not sure about a good mounting location for the original or the split.
This is what you are looking for to mount the original on the PanAm: denalielectronics.com/collections/horn-mounts/products/horn-mount-harley-davidson-pan-america-1250?variant=41067547951288
What if I connect directly with out suing the wiring harness. I want to replace the sound bomb compact with the split horn as I was advised by my mechanic. The compact version has been giving me headache whenever it rains it stops working. Now it has stopping working completely. So my mechanic advised me to get a split horn but told me that a wiring harness will still be useless.
At a minimum, you will likely need a universal horn mount: denalielectronics.com/collections/horn-mounts/products/hmt-00-10100-b?variant=15068507078756
These are great horns. I had the split horn fitted to my 2011 kawasaki Z1000. Finding a place for the compressor was a pain but managed to fit it behind the tall screen i fitted. The smaller horn I fitted to my 2021 husky 701. I also have a 2020 Gen 3 KTM 1290 superduke r which I'd like to fit the split horn some where descrete. I'm not keen on where you fitted the soundbomb on the KTM adventure in your video. Any idea's for my superduke r would be greatly appreciated. I'd also happily do an install video on my channel.
Greetings - thanks for the video - very helpful. The Original/Compact vs the Split - it appears as if they sound slightly different to each other in the video. Is this purely filming/handling, or does the tube make any difference to the output in any way? If you're in the room in the side by side test would you tell the difference? Thanks again.
Great question! Side by side in the shop or in our trade show booth, you can hear a slight difference between the two. I personally ride a bike with the split and a 4x4 with the original and I can't tell much difference in practice.
They are not submersible like our lighting products, but they are designed to withstand rain, harsh weather, and wet road conditions. Remember to always mount air horns upright so water can not collect in the acoustics.
Absolutely. Depending on the bike, there are a ton of different configurations that will work. We even sell a more "Harley-friendly" horn cover: denalielectronics.com/collections/all-horns
The SoundBomb Mini is the one you need! The mini should fit in the stock location and not require any additional wiring. denalielectronics.com/collections/soundbomb-horns/products/tt-sb-10200-b
Greetings. I have the same featured KTM 1290 Super Adventure S 2020 featured in the video. my question is will the unit fit nicely while there is a KTM oem skid plate installed?
It will interfere with the OEM skid plate. You could make some minor adjustments to the mount to make it fit, but that's not something we can recommend.
So from the test it looks like your soundbombs are really only 20db louder than a factory horn. Is it really worth the price and install for 20db? I am debating.
As mentioned by @Vvoltz a 10db increase equates to a ten times increase in sound pressure level (SPL) so 20db increase is equal to a 2000% increase in perceived sound, not a 20% increase. Hope that helps in your decision! Cheers
We like the way you think, but not quite. It would take a large array of horns to notice a difference in loudness. My math might be rusty, but something like 8 or 9 horns would be required to increase the decibels enough to notice.
We have a chrome cover specifically for the SoundBomb: denalielectronics.com/collections/soundbomb-horns/products/soundbomb%E2%84%A2-compact-horn-cover
Sound bomb mini is nowhere near the claimed db output, 115db claimed, 93bd output measured at your recommended distance, these snail horns aren't suitable for most bikes as they're just too big to install in the OEM location ... your snail horns are a copy of Mitsuba that have been fitted as OEM to Honda cars for yrs, which are a way louder horn than any Denali.
If your CanAm has a 12v battery, we have a wiring harness and a horn for your SxS. You will simply need to find a place to mount it and we have universal mounts for that as well.
Horrendous horn. Far too loud and the bracket is a shocking and dangerous design. Almost killed me when it fell out from bracket(after following instructions given) and James my steering. Please don’t buy this. It’s just not good.
We have never heard anyone complain that our horn is too loud, that's almost a compliment. What bike did you install your horn on and what mount was used?
@@DENALIElectronics really? Well, I guess you would say that. If you go on many of the motorcycle forums it does come up. What about your bracket for holding the horn in place?an inverted U and not a drilled hole. It’s your bracket that you would buy from somewhere like nippy Norman’s. I had to epoxy with Hysol, the screw as the nylon failed and it dropped out from the bracket. It was shocking. I followed the instructions implicitly
For maximum decibels, the trumpet should be turned open to traffic. However, with an install that is 100% exposed to the elements, we opted to turn the trumpet inward to avoid any splash up of rain or puddles.

1 is likely plenty and we have installed these on all kinds of trucks, 4x4s, and vans. All that is needed is a 12V source!
These can be an alternative to a full horn and compressor set like the truck dudes use!
We have a ton of customers use their SoundBombs on cars and trucks and love them!
