DIY Air Horns

I've had a few people interested in air horns so heres what I have
(not sure if theres a better place to put this for everyone to see)
I pieced together some random parts to hook up some air horns
I dont have a compressor yet because its out of the budget for now
The tank has a shradder valve on it so I fill the tank at home or at the gas station (feels like it takes forever but from empty to 120 psi only take a minute or two maybe)
parts list:
5 gallon air tank -$20 or $25
double trumpet horn- $53 (cheaper from ebay:TRUCK AIR HORN HORNS MEGA TRAIN 135 DUAL Trumpet INSANE | eBay but here is their website as well:TRUCK AIR HORN HORNS MEGA TRAIN 135 DUAL Trumpet INSANE | eBay
electric solenoid (came with horn)
15 ft of hose
momentary switch (check radio shack or somewhere online, the switch most horn companies sell is pretty bulky)
inline fuse
relay


I shoved the tank under the toolbox (it has a nice interference fit, not sure if I can even get it back out)

Used a piece of old hockey stick to mount the switch so I didnt have to drill any holes

This picture is hard to see but this is the inline fuse to the relay
With out the compressor you really dont need the relay. The solenoid only pulls about 3.5 amps which is low enough to pull through most momentary switch

Horns are mounted underneath the bed on the passenger side. There isnt much room underneath the hood of the Cummins or I would have tried to put it up front. The finish was really nice but hasnt held up to well to the PA winters


Heres a really proffesional schematic for you guys. I was planning on running a remote switch as well so I could use them from a pod on the key chain but its still on the to-do list


Here is some video for you guys as well
This one makes me laugh

I actually just got some 1/2" hose today to upgrade the 1/4" I.D. hose that I'm using now. I'll let you guys now if it makes any difference or not once I get around to swapping it

Very nice... I think you know mine will be up shortly as soon as I get a few things done...so the vid is how those horns sound??

Its not quite like the video of the chevy but I would say closer to their video then mine lol (the third video is pretty close)

I'll definitely have a better video from my iphone or gopro once I get the fittings for the 1/2" hose

Good deal...if anybody is looking for a good compressor and tank kit, 4wheelparts is running a special on the Klein kits...only $165 for a 1/2 gallon tank, 120 PSI compressor, pressure switch, tubing...

Oh ok, yeah I'm looking for a deeper one, idk what It would be like but deeper than the chevy

I spent alot of time looking for horns and listening to sound clips and any other ones were atleast double the price. This was the best sounding one I found that was on inexpensive
I was actually planning on using a set of horns off of one of my dads old work trucks but it would have cost as much for a solenoid and the fittings.

Oh yeah that's what I was finding also, looks like I'll wait for your vid and then go from there

nice job cody

You know what would be kick ass... If you could wire your train horns to go off with the alarm... Talk about scaring the **** put of a theft

I've been planning to wire in one of these for when people stand to close lol

Maybe wire up bed lights to another channel and idk what else lol

do a write up...PLEASE lol

I got a remote/relay from them for some future led's

Have you played with it at all?
Idk where I would have to mount the box so that it would get decent signal away from the truck
I could probably figure out how to boost the signal if I really had too...

^^ what he said about the write up

I had my Nathan's hooked up to my alarm
So when alarm went off i Forsure new it was my alarm

Thanks for all the help Cody!! Got me a 10 gallon tank for this, and got the horns on the way. And I think with all the pneumatic stuff we have here at work I can get the fittings and hose for free.

Can't wait to see... er, hear it!
I have all the 1/2" hose run and thought I was good to go but I need a different T/manifold from the tank, the one I got doesn't tighten/seal for some reason

I havnt played with mine yet, need $$$ for the **** to hook it up to haha ill let you know when I get to it though

Is it better to run 1/2" line instead of 1/4"?

Sent from my VS920 4G

I would do 1/2". 1/4 seems to small, at least 3/8

I'll let you know lol
I'm not sure if it'll make a difference because of te solenoid
Typically the more air you get to them the better
I'm kind of kicking myself for not going with 3/8" actually, 1/2" is a hefty hose
