HELLA 003399801 Supertone 12V High Tone/Low Tone Twin Horn Kit with Bracket

Loud and powerful Dual Supertone Horns add a level of safety to your driving with 118db(A) of sound.
Reviews
"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. They really sound like Mercedes Benz horns from the 1970s - early 2000s. Also note that these horns are actually quite large and may not fit where thd original horn was mounted. Fabricating mounts and installing all wiring to and from the horns and relay took a few more hours. 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 ground. Terminal 86: intermittent positive lead FROM steering wheel horn button TO original horn. Terminal 87: output TO new horns. Terminal 30: 12v constant with fuse 15A. Please Let me know if this review helps."
"This setup is for Subaru XV Crosstrek/ Impreza 2015 or older. ITEMS YOU NEED:Get it from Autozone."
"Like most men, I think a car can never have too much horsepower, a bank account can never be too big, and a horn can never be too loud. If you want a loud, nice-sounding horn, try some Fiamm Freeway blasters."
"Be forewarned, while these horns aren't the loudest ones on the market, they are pretty loud and a great upgrade over my stock horn and I've scared a person or two before. So far I've had no issues with anything electrical and the horns work and sound great."
"****DO NOT REMOVE THE BRACKETS FROM THE HORNS***** Unless you have an aftermarket bracket that instructs you to remove the hella brackets do not remove the brackets or they will sound terrible and vibrate anything touching them."
"Added these to my 2000 Jeep Cherokee after my OEM horns finally gave up."
"They sound and look great on my 2014 Toyota Corolla S+."

Reviews
"went to jail for beeping at a cop."
"I put horns in,on bed wall pointing down for inner horn dryness. I read that bracket will break in time so decided in bed so 1 day I am not dragging it with out knowing. Battery, accessory and solenoid to main feed, then to rear hookup with 1 fuse. Negative off horn solenoid went to switch at dash. Only other to do is maybe some kind of rain shield over top of horns."
"Reasonable price, loud horns."
"My husband had wanted a train horn for years and I finally ordered this for him for Christmas."
"I did upgrade those so I could put more ft lbs on the bolts with larger locking nuts. Horns and tank are right under passenger side bolted to the frame rail. I might search and buy 1-2 longer lower tone horns and add them into this setup."
"Bought almost 3 years ago and still works great, compressor has seen all conditions living in the Northern US including salt and has had no problems."
"These horns are pretty loud."
"insanely loud!"

Reviews
"I ordered the Stebel nautilus horn with this wiring harness to upgrade my stock horn on my 2007 Honda Shadow Spirit VT750C2 and it was such an easy install. Horn is much much louder than stock horn."
"The horn is indeed louder and beefier sounding than the original. Ironically, the sound this horn makes when the door lock "chirps" the horn is a little goofy."
"Installation requires a relay that is provided. After about 5 weeks the horn stopped working."
"It took 10 minutes to swap out the Relay and the STEBEL Horn."
"This is a really LOUD horn."
"Product details say 18 amp system... but that's just not enough power. Purchased a 30 amp/hr battery, the largest battery that will still fit on the bike... and I'm surprisingly underwhelmed."
"Wired this through a 40A relay, powered with a fused, 12 GA wire direct to the battery terminal."
"The OEM horn relay was plenty, but I had to up the fuse to 20A. I combined both OEM horn wires and crimped them to the new horn power wire connector."

"Added these to my 2000 Jeep Cherokee after my OEM horns finally gave up."
"i just got this so is not long-term review. good price, loud sound and a good tone and it grab distracted driver attention. what more do you need. (i hope this one last unlike the cheap china models. i had to change my horn 2 times and all died in one year )."
"It took some researching to figure out the best wiring and mounting approach for these, but the install was fairly straight forward once I spent some time planning it out."
"Installed on my 370z, no instructions on wiring but there are plenty of forums and videos online to assist with that."
"I used these to replace the stock horn on my Saturn LS1."
"LOUD AS HELL, I PUT THESE ON MY JOHN DEERE 1025R CAUSE SOME DUMB IDIOT COULD NOT CARE ABOUT A LOADER BACKING OUT OF A DRIVEWAY."
"You cannot really tell how loud they sound at all from that, although you'll be able to make out somewhat how the "distinct" noise is, with the dual tones."

"They do not sound stock, they sound a touch on the aggressive road rage side I work in a Bodyshop so I replace horns on all types of makes and models when they're recked and these are hands down louder then pretty much anything coming factory on ANY car ."

"This thing works good it is loud and it had everything except for the wiring that I needed to install it."
"For the money the horn is good."
"All I can say is Wow!"
"Material seems promising, Includes instructions. Cons: pretty difficult to insert the tube onto the compressor and yes it only comes with one meaning you'll have to cut it."
"A bit of modification to fit the Revco bracket if that's your application but in itself a great system for the price."
"I grounded out the compressor, then ran a wire from the compressor to the toggle switch, I then grounded the toggle switch, and ran the hot wire to the battery with an in line fuse, and HOOOOONKKKK."
"Even though is (Sometimes) creates a (Kinda) loud horn sound, the assembly parts are just not of good quality."
"I spent 3 hrs troubleshooting my wiring only to find the relay terminals had bad solder and had fallen apart."
