GAMPROGAMPRO 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 .

Amazing horn for the price you cannot beat it also very loud. I was surprised. I would definitely recommend it for $30. I don’t know how long it’ll last but definitely worth it.

Simple install and comically loud. Sounds like a big rig. I installed a toggle to turn it off and use only my factory horn for quick taps. And turn it back on when obnoxious is required.

Easy install. Does not sound like a train, but it is loud and obnoxious. I just bought my second one. The first one lasted 5 years.

I'm on my second one, first one lasted 5 years, people complain it doesn't sound like a train horn, I have mine hooked in conjunction with factory horn, that combo gives it a train horn sound. Nice and loud

The media could not be loaded. Alright I posted this video to help those who have the same questions I did. Almost a year later and the horn still working great because I did a proper install and secured things well with quality parts and connectors. here's the most critical info that took me the longest time to figure out:White- Goes to ground, MAKE SURE YOU'RE PROPERLY GROUNDED that is where I messed up initiallyBlue - goes to your original hornBlack - Also goes to groundRed - Follow the item description, it goes to the power sourceI was stuck and didn't know what was wrong and my problem was the grounding source I used wasn't proper, the paint and bolt I think preventing it from grounding. Secondly, you'll need:- some extra 16 or 18awg wire to extend to reach to your original horn or ground point depending on your car and location you install it.- Waterproof heatshrink butt connectors and male/female heat shrink connectors- Lastly, you'll probably need extra tubing. Take the vinyl tubing it comes with to a hardware store like lowes or home depot and make sure you get the right size diameter.Finally the video actually shows HOW IT SOUNDS, which no other reviews could show. And the seller doesn't have a simple audio clip for you to hear. In short it's nice and loud definitely what I hoped for.

Needed a replacement for one of our bigger dump trucks as it only came with a pee-wee Herman sounded horn from factory on such a big truck. One of my buddies waved at me one day and I so kindly honked with a big wave and smile…. well, soon after, I received a text from said buddy that wrote : “ why does that truck have such a lame Prius sounding horn?”. And from that moment…. my masculinity was ripped right from me as I sipped my iced coffee from my Stanley cup pondering how to handle this. I couldn’t be seen in public ever again until I did something about the situation. So, I ordered one of these horns thinking for sure it’s a gimmick for such a low price. And boy I was wrong!! The videos don’t do a justice on how loud and good this horn sounds. ( how long it will last will be a different story I think ). All jokes aside I am actually impressed. The grannies sleeping at the lights when it turns green will soon have their dentures flying out of their mouths at Mach 10 if they don’t move in .01 seconds. Because let me tell you… if they don’t, their back window will shatter with this faux Peterbuilt air horn sounding son of a g*n behind them with a new man behind the horn switch. I now drink my coffee black. Hide your kids hide your wife.

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.
