The Maximus IV kit is the extreme kit everyone is looking for. Saying this kit is loud is an understatement! This horn has long, loud blasts that will be heard for miles. Compare this sound to any of the other horns available and you will see why this is the biggest, meanest Maximus horn.
The horn that comes with the kit is the 175+dB quad train horn. It measures 16” long, 13” high, and 12” wide. This is a loud horn and it is the same one that comes with the Maximus Quad III, but NOW, you get a huge air system to power this beast. This horn has an upgraded 5 gallon high pressure steel tank. This allows for a much longer horn before having to worry about a loss in pressure and the resulting lower dB sound. The tank measures 18” long and 7.5” diameter. Of course, to fill this tank we provide the top Foxxair 100% duty cycle air compressor available.
This extreme kit comes with all of these parts:
· 175+ dB 4 bell train horn
· 5 gallon high pressure steel air tank. The measurements are: 18" long and the Diameter is 7.5"
· Level 3 Foxxair compressor - 100% duty cycle!
· Pressure gauge
· Toggle switch install kit
· Wires, relays, and necessary connectors
· 15ft Air Line
· Train horn cast manifold

The horn itself is bulky. It's a little tricky to find a mounting point for it. Easy to wire up and the sales staff is extremely helpful. I love it.

I see now why in the promo's I have seen they use the horn in a building or under a bridge over pass. This makes the horn sound better. Don't get me wrong this horn is loud. I would put it head to head against the real thing. It may not be as loud as the real thing but it gets the job done. Something for Myth busters. This was hard to put in,on a 2013 Nissan pathfinder. Should hove done a YouTube video on it.
