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 desertcart listing wiring diagram. Don't try to follow the wiring diagrams included in the box. The desertcart 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. Review: One LOUD horn! - Perfect. Easy install and obnoxiously LOUD!!

So no roof mount?** A: 2015 Silverado Lt. I have 6 individual trumpets in between the grill and the radiator. They are mounted around the edge of the radiator not to block air flow for cooling. 4 compressors are mounted in the front of engine compartment, two of the trumpet lines are 4'FOOT, and then the rest are at 3FOOT. They sound great and are LOUD! 4' would get you from the cowl in engine compartment up the windshiel/door piller to one side or other between roof liner and roof. You can test out the trumpet hose lenght before you do all that work. All together 6ct in my truck are VERY LOUD!!! Trains though still out do me but not by much .LOL signed, Huh? **Q: Can i wire to my original horn wires** A: Yes,of course. **Q: Whats the warranty on this, my horn has stopped working?** A: You probably need a new relay. That's what I am replacing on mine right now. They go out over time. Its a JD1912 12V 80A relay. Here is one on amazon: https://www.amazon.com/gp/product/B07W6Y7811/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 **Q: I bought two kits. What’s the best way to hook two of these up? Also has anyone used one compressor with air hose ran to two horns?** A: Just splice the horn wires into both. Compressor won't run both optimal. I ended up keeping stock horn on truck since when I lock my truck, the horn wasn't honking ( lock feedback) as if the compressor wasn't able to do it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to Install & Loud *by M***4 on May 31, 2026* I have a 1997 Ford F-250 7.3l powerstroke.

Easy install and obnoxiously LOUD!! Just what I wanted. ### ⭐⭐⭐⭐⭐ AWESOME! *by C***K on July 30, 2025* 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! ## Frequently Bought Together - GAMPRO 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 (SILVER) - Twidec/16MM Raised Speaker Horn Momentary Push Button Switch 5/8" Mounting Hole 12V Blue Led Light Black Stainless Steel Shell 1NO 1NC SPDT with Pre-wiring Wires Switch For Car Modification BKG16LB-BU - FARBIN Horn Push Button with Quick Connector, Momentary Switch with 3 Meters Wire, Round Red Cap Button Switch for Air Horn, DIY Electronics Accessories (Flat Button) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/129227664-gampro-12v-150db-air-horn-kit-18inch-chrome-zinc-single](https://www.desertcart.jp/products/129227664-gampro-12v-150db-air-horn-kit-18inch-chrome-zinc-single) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-24*
