Horn Location

I did not use the relay, if that is what you mean. I just added six inches to the stock harness, made a jumper for the ground, and twisted and re-bent the bracket. I can stand on the horn and the specified 18Amp draw will not blow the 15Amp fuse.

See pic for bracket mod. This points the outlet toward the grill.

Cool! Thanks for the picture.
 
i want a manly horn.

what is the best suggestion? I wouldnt mind a stupid ice cream truck sound or something.
 
Search the forum for other horn threads. The Stebel Nautilus compact dual air horn is a very popular replacement at 139dB.

Thanks for the pic. I did do a search before I posted and after your post for "horn" in the MS3 forums but did not turn up much. Searching for Nautilus turned up the right threads.

The Stebel website lists the current draw as <=18A (9A). Not sure what the "9A" means, perhaps average current draw?

I think I might get the Wolo Bad Boy. It is 118db. I am little concerned about 139db. Overkill IMHO and if it goes off near you, it can wreck your hearing.

Is the horn different between the 07 and 08 Speed3? I test drove a used 07 at the dealer and the sound of the horn was like a toy but my 08 has a good sounding sound.
 
Great thread! I definitely want to do something about my horn too. I have an 08 MS3 and it sounds so dinky!!! It definitely doesn't back up the power the car has! lol
 
I bought a low note horn for $16 at Autozone and added it to the current horn.

Here's a clip.

9A is for the 24V version, 18A is for the 12V version.

139dB does not sound loud inside the car, that is the rating 4" from the horn. It is not painful 10 feet in front of the car.

I also found this information about the Stebel Nautilus air horn.

"Keep this in mind: sound energy doubles for every 3 points you go up in the decibel scale. It means that the Stebel Nautilus horn, which produces 139 dB of sound, puts out a LOT more sound than these popular horns:
- 800% of the sound energy of the more expensive 130dB FIAMM Freeway Blaster;
- 600% louder than the $140, 130 dB Pro Pad Mini Beast horn;
- 650% louder than the $179, 128dB Rivco dual trumpet horn."

Well here's some confusing information for you...... was that from Stebel's site? My Freeway Blaster packaging stated 138 dB, Fiamm's site now states 130 dB, and I found them online listed at 132 dB. Perhaps they changed their testing, or they changed the manufacture of the horns after I bought them. In any case the Fiamms are far from "more expensive" than the stebel nautilus. The Stebel costs around $50 whereas each Fiamm costs $15. Also you can usually find the Fiamm's in an auto parts store and I've yet to see the stebel anywhere but online in my area, so add in shipping.

Stebels are stocked at O'Reilly's in my area.
 
Dual Horn install

Just installed a pair of Wolo 325-2T Maxi Sound Horn Chrome. Sounds like an new Denali. The dual horn with hi and low notes combined has a nice tone to it. Install was easy, just remove the left front fender well liner and the access to the existing horn is right there. There is already a second bracket in place with plenty of room to install the second horn (2007 MS3). I simply ran a jumper off the original lead to the second horn.

It's about a 400% improvement over the sorry ass horn that came on the car. I no longer sound like my dog's squeeky toy.
 
well, my horn stopped working. disconnected the battery to get rid of the CEL my fmic gave me, and now all i hear is a click, coming from the fuse. need to get it replaced.

Try the horn without the relay. My relay blew twice so far. It would seem mouting it in the wheel well is not a good idea unless you seal it.
