Stebel Nautilus Air Horn Install part 1

Stebel Nautilus Air Horn Install
I know several people have posted on this, but I have a bit of experience now after installing this horn, unfortunately, twice.

For more info see [URL=http://forums.nasioc.com/forums/showthread.php?t=1014647&page=1&pp=25&highlight=stebel]This Thread[/URL] .

Anyways, I installed the Stebel Nautilus full-sized horn in front of the battery on my 2002 WRX. I didn't use the relay, which indicated my first mistake, and secondly, I didn't heed Stebel's mounting recommendations. Regardless, it worked for a few months, then it sucked something into the intake, which locked up the compressor. Not good.

So, I purchased Stebel's new compact version of the Nautilus horn (see: [URL=http://www.stebel.it/stebel/index2006.htm]Stebel's web site[/URL] for more info and sound clips). Intrestingly, my local Advance Auto Parts carried the horn for $49, which made it on par with what I paid Griot's Garage with shipping. Regardless, I'm not going to fight Charlotte traffic without a horn, so I paid a slight premium.

I decided to mount the horn in the old Alarm Horn location, just above the cruise control unit on the stock bracket, which is attached to the passenger-side shock tower. I made a small L bracket out of a piece of flat steel I had laying around the shop. The factory bracket needs to bent slightly up to make it work.

Here are photos of the install:

This is a basic shot of the horn from the front of the car. I wired the ground to the passenger-side shock tower.

I wired the horn using the supplied relay, which I mounted just in front the battery. I had some existing loom cover I had run from this area over to the passenger-side shock tower area, so I just wrapped the wire into that. Then I ran a hot wire directly from the postive on the battery, through a blade fuse holder with a 20A fuse, to the relay. I used the factory ground on the driver's side fender for the relay ground. I then used the factory trigger wire from the factory horn (the one on on the grill side of the radiator, closest to the drivers' side headlamp). That wire is pretty long and easily reached the relay. I went the extra mile and put heatshrink around all of the connections to reduce the chance of the connections going bad.

Finally, the compact horn includes a snap-on hose barb for the intake on the compressor. Since I fried my first one, I wasn't going to take any more chances, so, I ran a piece of clear brake bleed tubing I had lying around through the main grommet just behind the and above the cruise control unit. Now, the horn gets its air supply from inside of the cabin, without the risk of water or too much dust infilitration.

The result: The horn literally scares people and has a nice, Italian sound to it. I had looked at the Hella Supertones, but they sounded a bit like a** for my tastes. The Stebel horn is both loud and sounds good. Also, since the horn is black, it blends into the engine compartment nicely and gives a nice factory look.

One other note: If you do this install, disable the horn chirp feature on your keyless entry/alarm. The pulse it sends to the horn isn't long enough for the compressor to build any pressure, so you just hear a slight whirr.

I hope this helps someone in their install.

Hehe, welcome Nautilus brother! :D I posted the thread that you linked to...but now I have included the relay and larger wiring, as well as the inline fuse to the battery. My horn is still mounted in the front grille...but I will probably lower it down a bit to use the bumper as a shield for fear of it "eating" something into the compressor. :D Great install...and happy honking, and scaring the living @$$ off people! :devil:

EDIT: The horn chirp and alarm work fine on my '06 :confused: with my Nautilus

Interesting that your horn chirp works. That may be due to it being a 2006 model. I would suggest you mount the horn somewhere where it won't run the risk of sucking in water. The older cars don't have enough room in front to mount the horn, so the passenger side firewall is really the only choice.

Yup...I am moving it down lower to be behind the bumper cover to shield it from water...I just didn't want to lose any sound! LOL :D It is a FUN FUN horn though!
Markymark409 06-24-2006 01:08 AM

ever notice any problems with heat? being right above the turbo? I just got one of these and am deciding where to mount it.
writersblock 06-25-2006 04:21 PM

It's been installed for several weeks now, and no problems. The cruise control unit sits right below it, so I assume that heat isn't that much of a problem. Also, the hood scoop vents outside air right above it. This solves two problems: One, it keeps heat to a minimum and two, it allows the sound a good path to go to scare off the tractor trailer that's about to kill me.

holy crap, are you really installing that thing? damn thats gonna be loud
wwiifanatic 06-25-2006 06:52 PM

I've had it in the car for 5 months.
markadopolus 06-25-2006 09:23 PM

^^^ Yup. I heard his before. Its pretty damn loud.
semaj 06-25-2006 09:29 PM

Louder than 139db?
wwiifanatic 06-26-2006 12:49 AM

Big rig loud. I don't know the decible rating but I run them at 100PSI. And the tone is deep.

very short clip. It's my pride and joy. ;)

Sorry kind of a thread hijack, but with this thing other horn threads simply amuse me. Perhaps this week I'll actually just make an install pics thread because I never got around to doing so.
semaj 06-26-2006 01:11 AM

That's pretty loud too...but it has a different sound to the Nautilus, which is more high pitched :D Very cool though...did you have to get a seperate compressor and tank for the air?
wwiifanatic 06-26-2006 01:24 AM

Compressor is mounted in front of the battery, and I have two small airtanks (4.5x5inch cylinders) mounted in the right fender. And yes, if you chirp the car when locking it the airhorns do chirp.

I ripped apart my 06 sti and found just about 0 place to mount the compact version of the nautilus, and the pics here are gonners? Anyone have pictures of their current installs?

I looked behind bumper splash guards, behind fog covers etc. I guess I could fab some crazy bracketry... I was just hoping this would be a cheap and quick install.
DaBoxerman 05-05-2007 11:34 PM

I installed the Stebel air horn today...........Alll I can say is....LOUD, Nice, Deep Tone = Perfect selection!

Not a high-pitched horn, but a nice train-sounding horn!
ronnyek 05-06-2007 01:27 AM

Just in case anyone were wondering what I ended up doing...

I'm currently running 2 Nautilus Compacts, still in my grille...and after all this time, still working great (even after a Canadian winter). :D
ronnyek 05-06-2007 12:27 PM

ehh be carefull with the grill mounting... direction itself state nowhere it might have access to elements incuding water etc... apparently the nautilus is particularly susceptible to failure due to moisture in horn
vica153 05-08-2007 05:45 PM

uh oh, I probably should move mine then. Its right in front just behind the grill. Although I guess I did already drive through tons of rain and snow with it. When I installed it, I was a bit worried about stuff getting in it so I put a some panty hose over the horns to stop bigs things from getting in.

Its so great to have instead the old 'meep meep' horn.
DaBoxerman 05-09-2007 04:35 PM

I also placed mine in the front grille area - You can't even tell anything extra is there. I have the black Stebel compact, which blends nicely with the black grille.

Hey downsti - How loud are your horns? I think we need to get a sound clip of that one.....Must be loud as a mutha'

Did you fabricate that bracket yourself?

[QUOTE=ronnyek;17975830]ehh be carefull with the grill mounting... direction itself state nowhere it might have access to elements incuding water etc... apparently the nautilus is particularly susceptible to failure due to moisture in horn[/QUOTE]

2 horns...1 year in the grille through Canadian rain and snow, no problems. If it breaks, I'll spend the $40 for a new one :p I just like it out in the open at the front for maximum loudness :devil:
ronnyek 05-09-2007 10:30 PM

yep... well future father in law and I... unrelated but check this custom fabrication... YEAH YUH! /me thrusts :disco::disco:

Looks great. And you're right, completely unrelated!

But for related info, I'm definitely getting an air horn now. I like the Nautilus Compact Truck horn. 300Hz = :banana: (D above middle C)
bigstrusk 08-10-2007 01:13 PM

Im tryin to figure out the mounting deal with my GC. It wont fit well where the stocker is (behind driver's side headlight) ... I mean i could probably stick it there and ziptie it in, but id like to physically mount it w/ a bolt. I'd like to avoid the custom fab bit as well, but we will see. Any GC owners go thru this yet?
