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 (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!

Easy to set up very straightforward sounds relatively loud, but nothing to extravagant

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.

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 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 picture Update!!!: 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

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 initially Blue - goes to your original horn Black - Also goes to ground Red - Follow the item description, it goes to the power source I 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.

The horn is pretty loud and it works well, however you can definitely tell it's $35 quality. The connections on the relay, as well as the connections to the pump are all exposed to outside elements. Even the fuse holder which seem protected, corrodes very easily, even though it was installed next to my battery. I installed the horn behind my grill on my F150 and the first time it rained it stopped working. It would then work intermittently and when I inspected it to see what the problem was, the entire relay and connections on the pump were corroded and covered in rust. This pump was installed less than 3 weeks and looked like it had been there for years. With that being said, it's $35. I requested a replacement and I am going to make sure to silicone all connections this time so they do not corrode if they get wet. UPDATE: After receiving the new one, I attempted to install and it wasn't working. I spent an hour troubleshooting and ultimately found the fuse was not making a good connection inside the fuse holder. It was covered in corrosion. Unbelievable after such a short period of time. I cleaned it out and installed a new fuse which resolved the issue and the new horn started working. I covered every connection in silicone, including the fuse holder. After a couple of weeks it is still working and have not had any issues this time around. The horn works fine as long as you protect the connections from the elements.

What a deal! Very loud. It will blow your doors off. Easy to install and includes everything needed.
