Viking HornsLoud Sound 129dB 2-Trumpet Compact Air-Horn-Kit, With Dual-Air-Compressors

Sounds like a real big rig and not a trumpet. the instructions made the install easy the hardest part was finding a location

The media could not be loaded.  Easy to install, mainly because I had help but if your doing it by your self you should have no issue of course. Most pole use these in trucks but I squeezed mine in my 13’ Dodge Charger. They work great! Blew a 20A Horn Fuse at first but I then replaced it with a 30A. Works great and sounds pretty good. As we all know it sounds better in person.How I hooked it up -Simply taking off the wires to the original horn and connecting it up to the compressor was how I did it. Very easy and simple. I was worried at first as the battery in my car is in the back but the 2 horns my car comes with stock are already wired so I just had to use there wires. I made sure to use my own 16 Gauge wire to ground the compressor.Overall -Overall it’s a good deal. Would definitely recommend over the cheap Chinese ones you see for $30, sure they may be cheap but if your putting these in a sedan it can be tricky and won’t be worth the hassle for something that would break easily, so get these instead!

Recent purchase, seems nice out of the box.Install relatively straightforward. Does not come with any wiring, though it does come with a relay in case you plan to use a different switch. You definitely need 16 and 18 ga wire, electrical connections/butt connectors/etc for install. Also, the compressors (especially) are NOT water tight and the recommendation is that they are installed within the engine bay in a dry area.Instructions are not correct for compressor installation - they say to have the compressor installed with air tube pointed down, however, this is impossible as the compressor has to be installed with the air tube pointed up. Not a big deal at all.The relay setup from the instructions is not the way that I had to connect it as I connected to an aftermarket switch in the cab and am using the factory horn for activation. Plenty of YT videos out there for relay setup for this.After install, this thing is LOUD! I am totally impressed with the noise it produces. Looking forward to use. I'm hoping that it lasts.

It is very loud. Overall a good product and good value. All metal horns and bracket. The pumps look good. One relay only. I purchased a high quality relay for these pups draw lots of current! I will also put a reversed bias diode to stop the spark on the relay contact (sparks is what kills the contacts after so many actuations. The diode stop the sparking, making the contacts last longer) How long is this horn going to last? I have no idea. Made in china. Hopefully enough to have the price paid worthwhile. Remains to be seen...

Just a lil more brain power figuring out the install and where to locate everything. But once I did, wow.... just what i wanted. Nice and loud... I think having 2 compressors made all the difference. Also i ordered the wire harness kit and made life much easier. Good buy. I'll try n do and video.

The install wasn't bad. I installed the compressors and the horns on the radiator support on my 2020 F-150.I went one step further and added a Remote control feature so no drilling or running wires into the cab. Here is the link for that.https://www.amazon.com/gp/product/B08CCVJWL9/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&th=1Make sure to use the supplied 30 AMP relay that comes with the horns.It said the remote is 20 amp... No way... But with the relay after the remote portion it works FLAWLESSLY!!They are loud and even more fun when no one is in the truck but you can hit the horns with the remote.... LOL!!!! Great Horns For The Price!!!

Setup the device twice. Then had someone else try to keep it working. Item keeps shutting down and stop working.

I gave it only three stars because I'm kind of upset that one of the compressors is not working. Both horns worked correctly one time. it doesn't make any sense because all the fuses have been checked and the horn relays as well. This is installed on 2017 Jeep Wrangler. you can hook both horns up to one compressor to work but the other one is not working. Followed the directions and installed them in place of the factory horns. This was a Christmas present has been only installed for maybe 3 weeks.
