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)

Works great so far and pretty solid kit. Relay is a little cheap or fragile but who cares , is easy to replace if it fails , the rest is solid and easy hook up .

loud and works well

I was pulling out of my drive way, heard it go off faintly and then It didn’t go off when I tried testing it shortly after. I already spent money on plastic rivets and installing it was a pain, the only thing that would change my mind on this review if I just got a faulty unit and they would send me another compressor, I am not returning the whole product it took me enough work to mount it. It sounded great when it worked.Update: I bought a second one kept the packaging all sealed up and returned it with the faulty compressor. So far it is holding up, I love this horn. I tapped it into the stock horn harness and what makes this really good is when my car alarm goes off it is really really loud. I love the sound for the price point and how compact it is. I will keep you updated and probably add a pictureUpdate!!!: Horn stopped working now. Lasted a couple of weeks and died. Do not buy!!Update!!: wiring just sucked and shifted a little bit, all good now. It felt wrong without it for a day

This horn is LOUD. I've had it for maybe close to a month now and it still works! Wiring it was definitely the tricky part but I found out how to wire it with no problem. There is a slight rattle when I use the horn but in most cases if it's the disk, that can be replaced. Overall, I've use this home to scare my buddies and alert those on the road and it seems to do a really good job!

Ok. Its not 150db. It may be ifyou use a certified db meter and measure at the appropriate distance, but at free air, no. However, it is still very loud. Im thinking, if 1 is good, 2 must be better, right? Easy to mount and wire. A good kit overall.

Great product for the price!!!

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 SwitchDude 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.

Recently installed on my F150 and I was more than pleasantly surprised even with all the good reviews. For the price, it's honestly incredible. It may not be $1000 true train horn loud but it's WAY louder and deeper than stock horns. Definitely enough to get someone's attention when needed better than regular horns. Wiring was simple, just cut the wires between my two stock horns and spliced in the white and blue wires. Can also use a separate switch but I wanted to be able to just smash my horn on the steering wheel when needed. Only been on a week but so far so good. Hopefully lasts a while but as cheap as it is, I'd buy 2 or 3 a year if that's what it took over a $500+ big tank setup.
