Decided to upgrade my F350 with the HELLA Supertone 12V High Tone/Low Tone Twin Horn Kit, I was going for something that demanded attention. And oh, it does—just not quite in the way I expected. Picture this: a beast of a truck that, when it honks, unleashes a sound you'd swear was a very angry, very loud Volkswagen. My dad can't stop laughing, and honestly, it’s become a bit of a running joke.About the horns themselves. First off, the red protective grill gives them a pretty cool look—if aesthetics are your thing, these don't disappoint. Installation was straightforward enough, not rocket science, but here's the kicker: these horns are LOUD. I mean, really loud. The kind of loud that gets everyone's attention on the road (and possibly a few startled glances, wondering where that sound is coming from).The twin horn setup, offering both high tone and low tone, creates a sound that's undeniably powerful, albeit not the deep, throaty honk you might expect from a truck. Instead, it’s a sharp, penetrating sound that slices through traffic noise with ease.So, would I recommend the HELLA Supertone Horns? Absolutely—if you're looking for something that packs a punch volume-wise and you can appreciate the humor in turning heads with a sound that defies expectations. Just be prepared for some confused looks and a good laugh, especially if your vehicle looks nothing like a Volkswagen

Got a Genesis Coupe R-Spec and the OEM horn has the balls of a flea. Honestly, sounds like a VW horn in the 70's. Terrible. Got these along with harness adapters they work perfectly! LOUD AND PROUD! No more embarrassment at the crap horn. HELLA RULES!

The HELLA Supertone Twin Horn Kit is a game-changer for my vehicle. The high tone and low tone horns produce an incredibly loud and clear sound, making sure I’m heard on the road. Installation was easy, and the red protective grill adds a nice touch of style. These horns are perfect for anyone looking to upgrade their vehicle’s horn system with powerful sound and reliability. Highly recommend if you want to make a statement while driving!

TLDR: Great and Loud horns!These horns are loud and will definitely get attention. These were installed in my 2018 Tesla Model 3 using the stock connector and a ford adapter from neoget here on Amazon. The stock mount had to be drilled out a bit but everything fit and was a super easy install.

I drive a small sports coupe with a wimpy horn which often gets overlooked/cut off in traffic. I installed these with the included relay and let me tell you they get people's attention. I did a lot of research on these so with that the installation/wiring was relatively straight forward and simple. The included diagram is a little confusing, so if you're like me with limited electrical experience you may want to fall back on an online tutorial (there are tons of them). Installing these requires you to remove your OEM horn(s) and I also had to cut one OEM horn connector to splice into the positive (+) signal wire. That is the only modification required to the vehicle itself but it should be mentioned. They function great, have a great appearance and are loud as heck. Some people expect a deep tone but these are pretty "sharp" and somewhat high pitched, but it's an ideal "alarming" tone.4 stars because they are packed rather crudely. The box is thin and there was no packing material what-so-ever inside, only a small thin flap of cardboard separating the two horns. Because of that mine were able to knock into each other in shipment resulting in some very small imperfections and scratches in the red grill paint. You have to be very close to see it but I expect better packing for the price and a company who has been making these for quite a while. My buddy ordered Sharptones and his horns at least came in separate plastic baggies, mine had no such luxury.

I now have 3 sets of these horns installed on my vehicles. I will soon be running 2 sets on one car as it is my personal show car and if Im driving it...whoever needs to be "alerted" will hear me!I am a car enthusiast as a hobby. I am one of those people who cant leave anything stock. Weather its a car, truck, SUV, call phones, laptop, etc...I have to modify it. And lets face it...stock factory car horns usually suck! In many cases it is embarrassing!Installation can be difficult depending on the car simply because these are larger than the factory horns and mounting them can be time consuming. Even knowing how to wire them in it still takes an afternoon to do a proper, clean install. Sometimes, to do a real clean install will take a day. These horns are NOT plug-n-play. They do require wiring and hardware not supplied. As everyones setup will be different, so it is impossible to include these parts in the kit.Once installed these horns work exactly as described....LOUD! Once you see the look of terror from some random driver the ends up with an ear-full of horn through there open drivers window, you will know the cost of these was justified.If you choose to hook these up to your alarm system as well, be ready for a very loud and almost obnoxious sound. These work great when hooked up to the alarm siren, even overpowering the siren in most cases.These are the best sounding horns out there. They are loud, sound great and perform every time. In no way are these cheap horns in terms of quality or performance. I will use these on every car I own and recommend them to everyone who asks.UPDATE: On my factory Nissan keyless entry, the horns sound funky and wimpy when locking the vehicle due to the short burst and most likely low voltage singal sent to the horns for the keyless system. It sounds aathmatic.UPDATE #2: The low pitch horn died on my wifes car. It now sounds funky as only the high pitch works. A little disappointed as these only lasted about 5 years for me now.

Louder horns, perfect quality. They look really good under the grill. They are a little high pitched but still sound good.Installation took 3 hours with zero experience, the longest part was getting the bumper clips on and off. Basic drilling through plastic for mounting and cable management was simple. With no electrical experience it was pretty straightforward, although the Hyundai adapter for the OEM horn was a little difficult to connect too. Purchase a universal horn wire harness it will make the job much easier.Also very resonable price, we will see if they hold up along with the wire harness.
