GAMPRO 12V 150dB Air Horn, 18Inch Chrome Zinc Single Trumpet Truck Horn with Compressor for Car Truck SUV Boat RV(Silver)

I have a 1997 Ford F-250 7.3l powerstroke. The truck is great and it only has 160k miles. Unfortunately, the original owner had an engine fire from the right side battery. A lot of parts were destroyed, original horn included. I bought it from the second owner who replaced all the melted parts and wiring harnesses, but he never did the horn. The trucks also been t-boned but that's a whole other story. Anyway, I needed a horn. Considering the turbo diesel 7.3l engine is so loud, I wanted something louder than a typical car horn. If I need to be heard, I don't want the horn to be drowned out by the loud engine. I heard good things about this GAMPRO air horn, so I decided to give it a try. Unfortunately, the retail box that they package the horn in is very low quality and was completely destroyed when I got it. Luckily only the trumpet part of the horn was dented and scratched, and mine won't be installed where anyone can see it. Everything else was still in the package and in good condition. The horn was really easy to install. I followed the Amazon listing wiring diagram. Don't try to follow the wiring diagrams included in the box. The Amazon ones are correct and much easier to understand. All the wiring goes through the relay and it works great with my original horn button on the steering wheel. The trucks has two batteries. I wired the horn on the right (passenger) side battery since that's where the original horn wiring is. There's an inline fuse close to the battery end of the wire. On vehicles with the battery on the opposite side of the original horn or in the rear of the engine bay, you might need a longer and thicker gauge 12v constant wire. I've used the horn dozens of times since I got it. I've used it in short rapid burst, a second or two, and even longer like 5-10 seconds. The horn seems to be consistently working well and very strong. I just have it zip tied in place, along with the compressor. I don't have a way to really test it, but it sounds and feels much louder than a standard horn. I can feel it vibrate when it's being used. It's facing down and behind the headlight, and it's still super loud. I bet it would be louder if it was mounted on top facing the front. Overall, I'm very happy with the air horn. It was easy to install and much louder than a stock horn. I've read some reviews that say the compressor is likely to fail every few years. I wouldn't mind having to buy a new one if I had to, as they're very fairly priced and you don't have to rewire the whole thing. I would definitely recommend this air horn to anyone looker for something lower and louder than their stock horn.

So I don’t usually write reviews cuz I don’t care to make the time but in case ur on the fence about buying this … it’s super loud and worth the price for sure. I’m gonna order a few more for all my other cars. Legit train horn loud af

I recently purchased the train horn from Amazon (https://amzn.to/3O5frpu), and I must say, it exceeded my expectations in many ways. The installation process was straightforward, and the build quality of the horn is impressive. It's evident that the manufacturer paid attention to detail. The horn's sound is nothing short of spectacular. Especially on this Japanese truck. It delivers a powerful and authentic train-like blast that grabs attention instantly. I've received numerous compliments from friends and neighbors, and it adds a fun and unique element to my vehicle. The neighborhood kids are giving me the horn pull signal when I come down the street to blast the horn. One of the standout features is the durability. Despite very regular use, the train horn has held up exceptionally well. It's resistant to weather conditions, and the materials used seem to be of high quality. This reliability is crucial for those looking for a long-lasting and effective addition to their vehicle. However, I deducted one star due to the slightly higher price compared to some other options on the market. While the quality justifies the cost, it might be a factor for budget-conscious buyers. In conclusion, the train horn from Amazon is a resounding success. Its easy installation, impressive sound quality, and durable build make it a worthwhile investment for those seeking an attention-grabbing and reliable addition to their vehicle. Despite the slightly higher price point, the overall satisfaction and joy it brings make it a purchase I don't regret.

I just put this in my 2003 Chevy Tahoe and it is better than what I expected. Easy install, easy fit, and sounds louder than I thought it would. About to pull up to my Mom’s to honk and get yelled at! Just make sure you have it grounded really well and you’re good to go.

You’re definitely getting your moneys worth for this horn! Just like everyone else has said in the reviews, this thing is definitely louder than you would have expected for the price you pay. The instructions are a little bit vague, but if you’re familiar with the electrical system on a vehicle, this will be a breeze. I hooked this horn up to my truck first, but decided I would rather invest a little bit more on a horn for a new truck, so I ended up strapping it to my motorcycle. As if my motorcycle didn’t make enough noise, this horn easily drowns out the exhaust noise, even while doing 70mph.

Works great, people move quickly after recovering from being stunned and looking for a tractor trailer. Install was a little tricky as I did not replace the factory horn instead installing a horn button in the front overhead console. Toyota Tacoma 2019

It barely works even after a replacement. The diaphragm is low quality or comes unlubricated. Frequently makes a voice Crack like 60 percent of the time. It only begins to get less infrequent as the horn "breaks in." It takes a while, but when it works it sounds great. Will report as things change.

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.

Easy to install and pretty load. Definitely a truck horn sound!

Bluddy loud like an air horn should be. Not a deep loud like a trombone more a trumpet.

Amazing sounds. I have so much fun with this thing! Super easy to hook up! If I were to buy again I would go louder. I would put this product on all of my trucks

Well so far it is just as advertised. Not a train horn but I never expected it to be. But it is a loud little air horn. If the pump lasts I will be more than happy with the product.

twin horn much better.
