These horns are extremely loud. The kit is very well put together. I had a few issues that had to be worked out like the pressure switch wasn’t turning the compressors off befor the pop off valve would release. That turned out to be a bad pop off valve got one off Amazon for 8 bucks works great now. The other issue was the big trumpet Mount broke so I contacted Viking and they sent me a new one so I braced all my horns and no problems now I love them they r the loudest ones where I live. If your lookin for loud crisp horns these are the ones they r great.

UPDATE: after 2 days BOTH compressors and a relay went bad. I put in a request to have both compressors replaced and I'll buy my own relays as these are not great. If they send me the new ones I'll change it back to 5 as it's resolved. If not, I'll return it as the tank and wires are not worth 558 doll hairs.This thing is so loud it hurts my ears and I am legally deaf. My chest shakes if the window is down. I mounted it on my 2008 F350 where the spare tire was under the bed. Welded and bolted some angle together. Made brackets to hold everything. Was a pain figuring out the wiring bc I have the dual compressor system w 2 relays that go to my uplifter switch then to a push button horn. But I'm about to switch to my steering wheel horn. So when I wantthe reg horn for inspection so I don't blow their ears I leave the uplifter switch down. When I want to let people know I'm alive and coming I leave the switch up or on.

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.

This horn is super loud and gets everyone's attention. Word to the wise, it does take up a lot of space. Having said that, the pressure switch or the pressure relief valve was bad and the system wouldn't shut off. The seller immediately sent replacement parts and has been a pleasure to work with.

Sounds nice been installed maybe a month now and one compressor already went out

This train horn kit came with everything needed to function right out of the box. I decided to upgrade some things such as getting a 90* fitting for the horn solenoid to attach directly to the tank, and a quick connect for airing tires etc. I used all included hardware to mount everything under my truck bed where the spare tire would be. The dual pumps air the tank up to 200psi very quick and the horns a crazy loud. They also are a deep tone which is awesome unlike other cheap ones that sounds like air horns instead of a train horn.

This system is extremely loud and looks really good under my 08 F350, system was pretty easy to install if you have mechanical and electrical knowledge. The instructions were very simple to follow and gave detailed wiring diagrams. Thier customer service is absolutely 💯 awesome! I had a horn break they sent a whole assembly out I welded a T bar in to support the weight of the large and medium sized horn.

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.
