12V 150DB Car Air Horns, 18 Inches Chrome Zinc Single Trumpet Truck Air Horn with Compressor for Any 12V Vehicles Trucks Lorrys Trains Boats Cars (BLACK)

I got this awesome old F-150 a month or so ago and I immediately noticed that the horn sounds like a clown car. I wanted something bigger and better and this air horn answered the call. It is a great sounding horn! Pros: -Epic honk Cons: -can be tricky to install (finding a place for the horn and the compressor and mounting them) -doesn’t come with separate switch or instructions to wire it via separate switch -the provided wiring is too short, IMO -the air tube is really short, only about a foot long. It really should come with 6-8 feet to accommodate more flexible installation options. -it might be illegally loud? Be careful. Don’t be obnoxious. Keep your stock horn as your primary. Install tips: I wired mine to a separate switch instead of to the OEM horn. That allows me to preserve the stock horn and wiring and to use the OEM horn when it’s more appropriate. But it required purchasing a separate switch and more complex wiring (thanks to ChatGPT for helping me figure it out). The wiring seemed really short. The hot wire is a couple of feet long but the negative wire is only about 6 inches. No idea how you’re supposed to make that work with just that, unless you mount the compressor right in top of the battery. You’ll probably want some extra wire, butt connectors, spare connectors, and T-taps on hand before you get started. I mounted the horn itself to a skid plate just under the radiator area. This horn is big (a foot or so long) and that was about the only place I could think to mount it internally. I installed the compressor using an L-shaped bracket I had laying around. I couldn’t find any large, flat panels that I could bolt it through. I purchased additional tubing at Lowes so I could extend the reach. I probably used 6 or so feet of tubing and it still sounds great. If you’re handy and can figure out the mounting and the wiring, then go for it! You won’t regret upgrading the confident, masculine sound of an air horn!

Best air horn! this is my third horn. The other two are 3 years old and still work like the day I installed it!

See video. This horn is loud, I had bought one for my 85 F250 it worked flawless. Mounted this one on my 2014 F150. Easy to do if you just look around and find spots to mount it. I had problems with the relay with water intrusion on my last truck (probably my fault) so be aware of where you mount yours.

The horn is awesome but some of the wires are a bit short so I had to buy some wire and add some length to make it reach. Other than that it works great and is VERY LOUD. If you know how to cut, strip and connect wires you can make it work with any vehicle.

Noise level good. Compressor good. Mounting had mechanic install professional.

I thought 1 might not be loud enough so I got 2... boy was I wrong. These things are super freaking loud holy crap. Seem to be well made and should last. One thing to note, though not really a bad thing. The compressors say 16A on them, they're fused @ 30A, the relay is rated for 80A but when I tested 1 horn it only pulled 0.3A. My guess is they print the amp rating higher so people think they're more powerful. I ended up wiring both horns to 1 relay fused @ 10A. If I run into any issues with this I'll update my listing. I'll also update if the horns take a crap. To get the air line thru the roof I used 3/4 gas fittings. flange, 3" nipple, Tee, Street 90 & a plug. If you do this make sure to use 3/4 so you have enough room to bend the air line 180 degrees. I used a tee instead if a 90 so I could stick something thru to help bend the air line through. I also had to buy some air line and a tee to join the horns together and found 5/8" fits best I stuffed duct seal into the opening the hose is coming out of to feed the horns so that no water wicked it's way back into my Sprinter. It's not shown in the picture but I used Henry 209XR rubber roofing cement to waterproof all the penetrations. Whatever you use make sure it's got some kind of UV inhibitor.

Ive had this horn since 2020 and installed on my golf cart. It is SUPER LOUD! Worth every penny.

Man this horn is loud, and awesome, this company rocks. I had horn for about 3 months. Thought I had installed it wrong, or had bad bad ground because it started to not honk most the time. I could hear the relay switch click, but no sound.. uggg right.. So then I blew air through the horn, it worked ✔️ The relay switched worked..✔️ So had to be compressor... I contacted the GAMPO through the Amazon system. Told them the issue, and they sent replacement compressor, even after having it for 3 months.. no flax, no hassle, just a, “we be glad to send you the part”! THAT ROCKS. Will for sure use them for other products. Don’t need a Switch Dude I was shocked when I saw a lot of YouTube videos putting in a south.... I wad like noooooooooooo I wanted to use my own horn switch from the steering wheel.. After I watched a couple more videos and study the diagram ( I YouTubed that to to make sure I was getting wiring right) I realized I could use the wires from original horn to attach to air horn, (you still need to run the main red Hot wire to the hot post), Took off old horn. You can cut wires: add connections, and add to the blue and white wire on air horn. The power wire had long enough lead could tie to hotpost outside fuse box. There are holes on the outside of frame for radiator and front grill, followed directions and kept everything close together. IT IS Louder than STOCK horn on your truck. If you never done this before.. don’t be afraid.. You can find lots of videos on how to take off grill, how to find out which is hot wire from the horn. If you used to working on your truck , no worries will nit take you long, if it’s your first time, plan a day so you don’t get in a hurry, don’t accidentally break your grill snaps becuse your in a hurry , and don’t feel rushed. I didn’t have to drill holes they were already in the frame, all though I did ream out the whole for the compressor hole for the large bolt that comes with the compressor. (Easy) and I only used one bolt for the horn, and put the relay switch on with that bolt. At ye bottom of the air horn I placed a zip tie on the bracket and attached to the frame just incas3 the bolt came loose an horn fell... ( not likely to happen.. I also did double nuts.. the only suggestion I would have for GAMPO is put in lock nuts for all the bolts. Love this Horn but not near as much as my sons do when they honk to scare a friend. Ha ha, I want to get a 2nd one to replace my other stock horn, nut I think that will be over kill.. if it’s not loud, I think you should check your compressor.. or use your air compressor at home to blow air through your horn.. you will know real quick if it’s the actual horn or compressor that came with the horn.. My father n law and brother n law will have an Awesome birthday presents this year! I am getting them this horn as well or their trucks.

So I just installed this horn in my 2010 Ford F-150. The stock horn sounded whimpy and I think a truck horn should have some gusto, no? I’ve used a few different types of these air horns in the past and what impressed me right off the hop was the fact that the horn is metal. It’s not some flimsy tin can metal either, it feels pretty substantial. Second, the compressor has some heft (weight) to it. The compressor’s of the horns I used in the past felt lighter and really just looked a bit cheapy. That being said, I’ve only had it installed for a week and they usually tend to go to shite by the end of winter/early spring so we’ll see how it holds up in the coming months. Thirdly, is it loud? Yeah, she puts out some decibels. I was actually quite surprised at how loud it actually was. Usually the company will boast that it’s but then you get it installed and you end up yelling out your window instead of using your horn because it gets it gets your point across better. With this horn, not the case. I honked at a car earlier today at an intersection and everyone on standing each corner jumped. It gets the attention it’s intended to. It’s not an air tank/compressor horn loud, but loud enough 😉. Install was easy enough once I figured out the spaghetti bowl of wires (I am not technically inclined in these matters) but there are plenty of videos on YouTube if you get stuck. If I had only one comment to make it would be that the kit should include a ring clamp or something to make sure the air line doesn’t come unattached at either the horn or the compressor. At the very least a pair of zip-ties. But I digress, if that’s the only thing I can complain about then that’s pretty all right. All-in-all, GREAT quality, GREAT price point, EASY install & LOUD. If you’re thinking about it, stop thinking and buy it.

Works great & was a good price too

Impressed. better than expected. Installed on my GMC Sierra 3500HD and now sounds loud. Its fun watching people jump!!

Awesome deep truck horn sound and instantaneous "Get outa the way" warning
