Where is the best place to install air horns?

[632 Regal]

I wonder if somethings wrong with one or both of yours, mine are loud! Dont want to blow them inside a closed garage with the windows open for sure.

I have actually...and I can't hear the difference.

Mine are mounted horizontally in the front grill... and are painted black.

I've allways though that the BMW's horn was plenty loud.

Gotta agree with Ralph here, best place to install air horns is in someone else's car. (only joking!). Either that, or fit a big truck horn, 175dB - that'll do nicely!!!

Cheers,

No real place to put in truck horn. My horn is super wimpy... must be broken. Only real place to truck horn is under the trunk area but doing so will be like a big rig right on tail and you freak yourself out! LOL

It could go sideways across the front of the car, just below/in front of the rad. Of course, no one here would be juvenile enough to blast the hooter at the local drive through and shatter the windows!

Cheers,

in my motoor cycle days i used to mount air horns...the existing bmw horns are behind the grill there is probably room for the compressor.I used to always use a relay with the existing horn circuit to open and close it with a wire and fusse from the battery or in our case the battery post under the bonnet.My car has the loudest horn of any car i have had

i had these on my saturn and i hated the high pitched sound they made...sounded super weak...jon k has something similiar in that he bought ferrari horns but to my ears they sound too high and squeeky....

i'd like to have some truck horns...that'd be fun

Where should I install my uga horn? The biggest problem I have is finding a place to mount a switch tastefully on the inside. I want to keep it seperate from my regular horn.

Used to have them Hella horns on my old car and I really miss them compared to the "Roots" style horns we got. I prefer that old sound, it's different. I don't know how loud they are compared to the uga ones but my old ones were SUPER loud! (I am a fan of Hella products) I could drive up next to anyone and scare the jeepers out of them! But I lived abroad where you NEED loud horns to drive you are beeping every 10 seconds and it's actually illegal if you DON'T use your horn LOL!! Ever heard of that??? In the US you don't need a loud horn except for novelty. (don't forget some consider these horns illegal)

As for mounting it is most convinient near the airbox on the passenger side in front of the wheelwell. They won't get wet and they should be quite audible having to penetrate through less layers...(In my old car they were mounted on the firewall and could be heard plenty!) You don't want them in a place that they will get direct water. Don't ask how I know. In the grill will make them sound the loudest of course but it will be a more complicated install (unless you like taking the front grill off) I would recommend facing them sideways for minimal water exposure (I don't know how else you'd have room anyways).

As for a switch you can put a subtle 3 position rocker switch right in that blank (reserved for rear fog-light I think) to the left of the front-fog-light switch. Or if you have traction control, there is a blank in that panel....If you've used those spots you can mount it on the left carpeted side of your console. Easily acessible though out of sight. I have a switch there and it looks and works great. Under the dash is difficult as there is a metal backing to the panel and harder to cut through, but it can be done. Don't forget as mentioned you need a relay to wire properly.

I installed them on the left hand side and left the right horn there as stock. There are 2 red horns. I didn't wire up the relay, I just used the stock connection and modified, seen in the previous pick. It wasn't working last time becasue I had the positive and negative cables the wrong way
