Mega Blast Air Horns For Trucks, Cars, SUVs, Train Sound, Extremely Loud, Black

I order alot of stuff on Amazon but don't have much time to do reviews, however I am so impressed with these horns had to do one. I recently installed the MegaBlast Horn on my boat, and the experience has been nothing short of exceptional. The horn performs incredibly well, providing a piercing, loud sound that is ideal for marine applications. Installation: The installation process required a bit of customization on my part. The package does not come with a bracket for mounting the horn or the two air compressors, so I fabricated my own out of aluminum angle and flat pieces purchased at home depot. Additionally, I installed two relays and wired them into the boat's fuse box. Performance: The MegaBlast Horn delivers on its promise of high-volume output. The sound is loud and crisp, effectively serving its purpose of alerting nearby watercraft, which is an essential safety feature while navigating waters. Overall: The MegaBlast Horn has exceeded my expectations. Although a bit of customization was needed for installation, the effort was absolutely worth it. I now have peace of mind knowing that I have a top-quality horn ready to perform when needed. If you're considering installing a horn for marine use, I would highly recommend the MegaBlast Horn for its unmatched performance and reliability.

I own a Sedan, and I couldn't be happier to discover that I can easily fit a set of these air horns (even two) behind the grill and in front of the radiator. It's a powerful alternative for people like me who don't want to install a whole air tank just to get a train sound. I had previously tried some similar air horns with two compressors, but I ended up returning them because they didn't produce the loud sound they claimed. However, I decided to give this one a last chance, and I'm immensely grateful that I did. This air horn produces exactly the sound I was looking for—I'm overjoyed with the result. Though, I must admit, my neighbors aren't as thrilled about it.

Don't you hate those wimpy stock horns? Well I was having compensation issues.... big truck small - you know what- so in order to satisfy my short comings driving a full sized truck, I added in this horn. I just have this to say, the video does not do the loudness of this horn justice, it is way louder than what is represented in the video. This horn certainly does turn heads when activated, people will jump, puppies will cry, your passenger will be embarrassed (after laughing their butt off first) As other reviews have said, you have to be a bit handy to be able to wire this correctly since you have provide your own wiring to make all the connections, and in my case with the Toyota Tundra, I had to craft a bracket to mount the dual compressors under the engine bay. So if you are suffering from big truck small "horn" issues, do not hesitate to get these horns installed, your local mechanic will giggle when you ask them to test your horn the next time your vehicle is in the shop.

These horns are quite a bit louder than my standard horns. They don't come with a wiring harness and the relays and sockets aren't waterproof so you'll have to use a bit of ingenuity to install them. Beyond that the are great horns! I used a timer to have these come on a couple of seconds after my oem horns so they won't activate with short burst.

Installed for about a week now. Very well built and quite loud. Wiring is easy since it's going thru the relay. Biggest obstacle was finding a suitable place to mount the compressors. Update (Dec. 9, 2025) - Horns are still going strong despite being exposed to the elements (Northeast weather). The compressors are going strong (oil them regularly). The horns themselves show no rust/defects and sound just as powerful as they did on Day1. Only mod I have made was replace the relays this past summer with Nylint waterproof ones but otherwise excellent product.

I found them very easy to wire up. I have minimal experience running electrical wiring, having just started tinkering with lighting and hardwiring my cellphone booster on my truck. I have a 2022 Ram with the auxiliary buttons built in, so that makes it much easier, but I can't imagine it would be too much harder regardless. They send you the relays, you just need to purchase wiring and the little connectors separately. They are surprisingly loud, comparable imo to the 500+ dollar kits available with the big separate compressor. I'd like another deeper tone, so I may purchase another different sized horn to attach to another compressor. I honestly didn't expect them to be this good.

The horn sounds like a train exactly what I wanted but you will have to make your own harness for it and possibly weld up a bracket like I did for my tundra. I put it on a momentary switch, the instructions they gave me didn’t work at all with the diagram I went off in the instructions caused my horn to only work with truck off. So if you end up like me throw away the instructions and look up another diagram for a 30amp relay and that should do you much better

I’ve been shopping around for a horn like this for a while and looking at various types. The MegaBlast Air Horn did not disappoint. It’s loud enough to get the attention you need and don’t need that additional air tank. Installation was pretty straight forward but the dual relays did surprise me. If you wanted to wire them independently for individual notes it is a good setup. I would definitely buy again and recommend it.

Cheese and rice, this loud horn is really loud. Total carbon copy of a big-rig sound, and I got the recommended dash button too. This horn is awesome for letting everyone on the block know you are there, scaring disbelieving car mechanics, and getting those dirty squeegee gypsies away from the vehicle. Money well spent. 10/10 would buy again.

Exceeded my expectations
