Hella003399801 Supertone 12V High Tone/Low Tone Twin Horn Kit with Red Protective Grill, 2 Horns

Easy to install to stock system. Bolt on and plug in. Great look too!

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!

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

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.

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!

Installed this horn kit in a 2000 Toyota Corolla. After that no one cut me off again and always got out of my way.

This is my 3rd set of Hella Supertone horns. The first 2 were purchased long ago to upgrade the sound of a Mercedes and Land Rover. They were made in Germany. This set was made in India. Other than buying factory replacement horns for a vehicle whose horn sound you like, buying horns based on an expectation of a certain sound or tone is actually quite difficult. I like the sound of the Supertones, but I knew that before buying them.They really sound like Mercedes Benz horns from the 1970s - early 2000s. If you like that sound, you will certainly like these. Others may find the sound kind of shrill. One thing is for sure: any prolonged blast is impossible to ignore. You will be noticed. You will be heard.These horns are directional, so attention and planning should be made to aim them forward if possible. The enclosed mounting "bracket" is useable only if you are replacing a similar style horn. Please note that you may need to fabricate a custom bracket to mount the horns properly. This is what I needed to do. Also note that these horns are actually quite large and may not fit where thd original horn was mounted. I prefer the slightly smaller 4 inch horn for ease of fitment.These were installed in a 2007 Ford Escape. I had to remove both inside front fender liners and the front bumper cover to access the original horn. Disassenbly and reassembly took over 4 hours. Fabricating mounts and installing all wiring to and from the horns and relay took a few more hours. It was worth it, but it was a full days work. Plan your time accordingly.I must note that you must use the included relay or be certain that your own vehicle has a dedicated 15 amp circuit for the original horn. Most will not. Failure to wire horn as instructed will result in lower volume. This voltage drop accounts for some of the poor reviews of this product. Also, the instructions are very clear only if you are used to reading electrical diagrams. Otherwise, they stink.Hella Relay Wiring Instructions:These instructions are for vehicles where the horn button supplies power to the horn when depressed and the ground is constant.Terminal 85: chassis groundTerminal 86: intermittent positive lead FROM steering wheel horn button TO original hornTerminal 87: output TO new hornsTerminal 30: 12v constant with fuse 15APlease Let me know if this review helps.Good luck.
