12V 135db Air Horn, Dual Trumpet Air Horn with Compressor, Super Loud Powerful Train Sound Shiny for Any 12V Vehicles Trucks Lorrys Trains Boats Cars Van

I ordered this product as a cheap replacement for my OEM horn after it broke. Seeking a bigger footprint for a small dollar amount, I decided on this product. First off, let me say how sturdy the build quality is. The compressor, the horns (even being plastic feel well made), and the mounting parts. I am not worried about any part of this breaking under normal driving conditions. Second, this horn is loud. Very VERY close to the advertised 135db, which is exactly what I was looking for. Even without a full sized air compressor, this product packs quite a punch. It is a very good choice for those looking for a powerful horn, but not wanting to pay for a full sized air compressor. Lastly, the ease of installation really made this product a full 5 stars for me. Even if you have minimal electrical/mechanical experience, installation is a breeze and can be done in as little at 15 minutes. Overall, I am VERY satisfied with this particular horn package and will probably be reordering this same one as a replacement in the event that mine does break.

Dropped my bike on the freeway when cars that wouldn't use their turn signals were trying to merge into my lane and all of the cars in front of me came to a sudden stop. A louder horn would've been very helpful. This is great for the price. Easy install until I realized my motorcycle had more fairing damage than I initially thought. The video doesn't do it justice. It sounds much louder and echos a little. I do wish it was a deeper tone but this will do fine.

A jet engine at take off is 140 decibels this it 135 so its pretty loud. One of the horns was cracked when i got it but it doesn't effect use, compressor seems high quality tho. Very easy to wire if you know what your doing with the relay, the directions were no help. YouTube will probably be your best friend if you need a walk thru. It fit well in my 2000 jeep xj compressor on front of the air box and horns behind. It comes with enough tube to face them forwards, very limited with the mounting points but just as long as they dont bounce around to much they should be alright. Nice for when people cut you off.

My favorite horn, have one each of my five trucks

I bought this air horn so my dinky Honda can actually get the attention of any other vehicle that wants to run me off the road. For that purpose, this air horn does that nicely. However, mounting the compressor to the car was quite a challenge. The main issue is the mounting slot that is cast into the side of the compressor housing and the measly hardware that comes in the packaging. First, the slot is angled in the inside location so when a bolt is tightened down, it works it's way down the slot and eventually falls out of the slot, effectively unmounting the compressor from the car. I ended up putting a hose clamp around the mounting slot so the bolt couldn't walk down the slot and would stay secure. Second, there are no lock washers in the kit so you have to crank down on the nuts and bolts to secure the compressor and horns and even then, you're never sure that the nuts aren't going to come loose and something will either start rattling or fall off. I ended up replacing the bolt with a longer one, installed lock washers and secured the grounding wire with a nylock nut. Third, the wimpy brackets that come in the kit leave a lot to be desired. When I finally got a bracket attached to the compressor, it didn't stick out far enough away from the computer body to be able to mount the compressor to the car. I ended up putting 2 brackets together and mounted the outermost bracket to the car but I had to drill the mounting hole larger to fit the bolt that carne with the original horn installation. As for the horns themselves, since I had to use 2 of the brackets on the compressor, there wasn't enough for both horns. So, I ended up reusing the horns from my old air horn and just used cable ties to secure them, which worked fine. Essentially, all I really needed was a new compressor. I've got a pair of nice horns to give away to anyone who wants them. I have the overall rating of this air horn a 3 stars but that's only because the compressor worked and I got it to make a loud sound. For mounting, I have it a 1 star but it should have been less.

For the money this thing works great. Nice and loud. Loud enough to make you plug your ears if you’re right in front of it. I have had expensive “train horns” before. These aren’t that loud. But for the dollars spent, you won’t be disappointed. Made of pretty thin plastic. I got mine mounted with the hose provided but you might need more. Also some basic understanding of 12v wiring might help. Came with most parts needed. Everything came intact with nothing broken or missing. I wired it to a second horn switch. Over all I am beyond satisfied with what I got for the money spent.

This thing is a toy that sounds like the first note of the Mexican ice cream trucks song. It's cheap and definitely not loud. My regular horn in my Grand Marquis has more authority than this thing. The sound is embarrassing really and every time I pressed the lock button on my keyfob I'd have to hear it so I decided to return it. Turns out the return window closed yesterday! I'm just gonna throw it in the trash. Installation was whatever, it's not super simple and if you don't have a little knowledge on it, the directions will leave you with more questions than answers.

This horn sounds great. This here is a demonstration of the horn when all setup. Personally I couldn’t instal it myself so I went ahead and went to my local audio shop and well, they charged like 175. Not a bad price for the precise job they did. This unit is great. Loud sounding, very subtle. Can be used for negative or positive. To thank or to say f** you!! Great horn really. Thank you GAMPRO! Wouldn’t suggest trying to install yourself, very complicated.
