HK12V 150db Air Train Horn Kit with Compressor Single Trumpet Air Horn Powerful Loud for Trucks Cars Boat SUV Train (Black)

I bought two. Insanely loud but I still want two more. Called my neighbor and had them go outside after I drove 1/4 mile away and honked form them. It was so loud they were laughing.

The media could not be loaded. I got this because nobody in my town can drive, and the factory horns on my car weren’t cutting it. The horn isn’t super loud compared to those train horns, but still leagues better than the stock little “meep meep” noisemaker that Subaru dares to call a horn. I drove around my neighborhood after I installed it and listened to it boom and echo across the whole block. I almost feel bad for my neighbors now, because this thing was way too fun to test out. If you buy this, you’ll probably have to get some extra wire and solder some things together, which is exactly what I had to do, but it was well worth it in the end.

This horn is most definitely loud no arguing that! I'm just glad I had more connectors because every one of them that came with the wiring broke right off during install. Not a lot of length to the wires either, I had some of that I added to thr exsisting as well luckily. I would recommend having both on hand for the install. If you need to hook this to a switch instead of your horn jump your positive wire to your battery instead of the negative! Would recommend!

The media could not be loaded. For the price I didn't expect it to be made so good and sounds Great! And very loud!! I'm 71 yr old and installed it in my old truck in 30 minutes and i did it right. Everything u need is in the box but i did use some self tapping screws instead a few that was supplied..

Product stopped working the day after it was fitted.... Both air compressors are completely dead!Hope the replacements sent will last....Since I can't contact you directly and Amazon is making it impossible to have direct access to a REAL person to sort this out, I'm leaving my response here!As an international buyer, this is very concerning....Now I am expected to send the old Units back, at my expense! This is not happening....Sending it back again with DHL will cost the same as my original purchase.Amazon has my delivery address, you can arrange pickup on your own... I'm not paying for this to be sent back, and will also not be billed for the replacement units.Parts will be available for pick-up for the next 4 weeks.... Then it is going into the bin.

Its loud. It has installation instructions. Pretty easy to hook up. You will be glad you did.

If you’re looking for something other than a air horn with a tank and compressor n get ya close to that then this the best I’ve found so far.... it’s not a Kleinn but it’s also not 300ish.... if ya didn’t know the longer the trumpet the deeper it is... I believe this is 16.5” and anything over 16” is what anyone should be looking for.... the electric compressor seems a tad bigger than most your standard so I was alil skeptical at first but the sound isn’t so bad.... if ya know what you’re doing install is simple just get a momentary horn button.... install took about a hour n tht was just really looking for a location under the hood

Compressor doesnt produce enough pressure. Horn is loud but not if powered by supplied air compressor.

Loud enough to get attention but not so loud as a train - yea, right. Simple to install and all the parts are there. Everything you need. Cheap efficient. I wish the clear plastic hose was a little longer though by a foot. It fit behind the grill out of site. This is plenty long enough when trying to find a spot to place it. This horn supplemented with the factory horns is just right. The lower tone works well. Not as loud as a semi, but noticeable!

Difícil de instalar, pero después de todo si funciono, llego deteriorada, pero con la reparación ya funciono.

Mega gut mega laut perfekt

I purchased this to change my main horn on my car with. It was easy to install - just had to connect the car wiring to the horn relay and connect it all up. The hardest part was probably mounting the horn unit under the bonnet - I used the supplied clips and a good number of cable ties and it hasn't budged at all.Seems to be well made for the price of it and has been working well - it is quite loud! Not quite truck loud, but louder than a standard car horn.
