Viking HornsV103C2X-6-12/311-1 Super Loud 170 Decibels Train Air Horn Kit, With DUAL 200 PSI Air Compressors

Where do I begin…All in all this is a great budget friendly alternative for anyone looking to get into the train horn system for a truck car or whatever you drive.I had a small mishap with my kit as it didn’t contain the air pressure switch that turns the compressors on and off the vendor was quick to remedy that.You will have to do your homework with the electrical, they are two 30 amp compressors - when you do the math that ends up being about 10 gauge wire to each compressor. The other issue is the cheaply made relays, the housing is absolute garbage the minute I plug any sort of a wire into one I could hear/feel the internal workings pivoting back-and-forth. I opted to replace them with a set of “Heavy duty“ waterproof pre-wired relays.The tank is heavy that being said make sure you size your support carrier accordingly, last thing you want is this thing to go flying out from wherever you have it. As you can see from my pictures I mounted mine underneath the truck where the old spare tire used to hang out.Now for the obvious question; is it loud?Add a full 200 PSI when the air valve opens and dumps that amount of pressure through a half inch line into the horns if you’re standing anywhere near them you will need some sort of earpros or you’ll be sorry. I equated to someone popping off a 6.5 Creedmoor while you’re standing about 10 feet away without hearing protection.All in all, I love the kit. You just need to be very handy in order to get it fully assembled into your application if you’re looking for plug and play this is not it.Edit:One thing I forgot to note, is that I added two Vixen water filters (50 µm) each on each compressor. I also added an ARB externally mounted airline connection for airing up tires, etc.

First of all the horns sound great, they are loud and pretty easy to install. The reason for the 2 stars is the air tank has a small pin hole leak on one of the welds for a nozzle, and how I have them mounted under my truck it's going to be a major pain to try to get good pictures of the leak without buying extra wire to make extensions for the plugs to have the compressors and tank on the ground where I can put soapy water on the hole to send viking pictures of the leak, and that's the only way they will do anything about my leaking tank. If it wasn't for the leaking tank and the difficulty in getting the tank exchanged I would have given the horns 5 stars. Good thing is I have a buddy who's a welder and he's going to repair the tank for me.I updated my rating from 2 stars to 4 stars, due to the fact that after several messages back and forth with Viking horns is resolving my issue.

I had done quite a bit of research on getting a train horn for my truck. Average prices was between $500-$900 pending manufacturer. So I kept searching as this was over my budget. Then I came across Viking Horns. Little more research and some videos and I decided to take a chance and at $384 it was within my budget.In the kit you get pretty much everything you need to install the system. You will need some extra electrical wire, connectors and some MacGuyvering abilities.If I recall the supplied instructions say to mount the dual air compressors in the engine bay but then the hoses are only 20" so that's not going to work when the tank is in the back of the truck.So what I did is removed the spare tire carrier (can't use it anyways with oversized tires) and mounted the tank directly behind the rear license plate/ bumper inverted. I had to make a custom bracket for this. The dual compressors which work nicely, a little loud and from empty to 200psi with a 5 gallon tank takes about 4 minutes, I installed inverted under the bed also. I used some recycled aluminum 3/16" plate for my mounting plates. They come with rubber "bumpers" which I will upgrade later as they rattle the bed of the truck a bit. Or I will put some foam between the plates and the frame.The horns were installed pointed to the back of the truck behind the rear axle. This was to prevent water from going into the horns.Hoses and connections were pretty straight forward. The connectors work ok, not great though. The compression fittings do their job, it is just with a semi rigid hose and some tight turns it makes for a weak joint. But it all works in the end.Electrical, unless you know your way around it, I suggest your local mechanic, car stereo guy etc. It is not that it is difficult just time consuming and from the back of the truck to the front and negotiating wire runs is around18' of travel.The free horn button, leave it in the box, get one on Amazon for $8.After it was fully installed the tank would only get to 160PSI and would only put out 132decibles. The description says 200psi and 172db. I emailed VH and they sent me out a new pressure regulator and that solved the problem. I do not blame them, parts can fail no matter where you buy them from. I received the replacement within 48 hrs (we are both in the same state) and bingo, 200psi and about 165db. Let me tell you it is LOUD! I was at a truck rally 3 miles from home and my wife said she could faintly hear it.So here is my take on the system. Bang for the buck, definitely. Installation instructions, not the best. Parts and supplies, very good (if your going to install it in a beetle then you will have everything you will need) Customer service, excellent. Continuous blast time, approx 12 seconds. Loudness level, enough to piss off your neighbors and the ones on the next street too.As a note, I just purchased a 2nd 5gal tank to install in the tool box. This will give me 10gal of 200psi and about 25 seconds of air time.Oh and yes you will have 1 extra port on your air tank if you choose to run a dedicated air line for tools, tires or even an air ride system.Should you take a chance on a young company, I did and I am very satisfied.

This Horn is Legit, Sounds just like a train horn, last horn I had sounded like a loud air horn, this sounds legit like a Train, and is stupid loud, doesn't matter where you install it at your gonna hear it for sure, the last horn I had was a vixxen sounded good and loud, but didn't have the train sound, also the compressor went bad within a year, the only down side i have for this is the compressor's, it does come with 2, but with the amperage draw they both bog down and stop working, but 1 at a time there fine, I made a manual switch off which I can detach and reattach each compressor seperatly, But aside from that there are literally no functioanlity issues, also I was able to use a blank plug port, for a 1/4 air hose adapter instead of the plug, so i have on board air now, ..... it is great i'll take a video of the horn and the sound and upload later on., changing the review, customer service sucks, one of my compressors went bad, and there not doing anything about, horrible
