Jeez, the horn on my new Mazda5 is the absolute wimpiest horn I've ever heard! I'm a fairly aggressive driver and use my horn occasionally to wake up some dim-witted drivers.

I gotta say, I'm EMBARRASSED to hit the horn in this car. People laugh at me.

Are there aftermarket horns to consider? A Peterbilt air horn would be nice but even a strong "beep" would be a huge improvement.

 

Yes they are a bit wimpy sounding eh? I'm sure any horn will do but will probably require cutting of the wire.

 

hi john i thought it was me .i blow the horn . nobody seems to hear it lol i had a guy on a cell phone drift over in my lane i hit the horn he ran me off the road.. with cars now adays.. if you have the windows up on your car . you cant hear much of any thing spencerfvee...............................

 

Man they are the wimpiest, one of the things I'll change. Autozone has these for $19.95

Blazer/High and low tone replacement twin horns (BH201C) | Horn | AutoZone.com


Advance auto parts has a pair that looks the same but they want $5.00 more.

 

I came across this a while back, it seems it would be easier to just pull the "skid plate" off the bottom and go from there.

It's the same way with the 3. For some reason Mazda put dual tone horns in Eu markets, but not in the US. Instead they have a single Fiamm high tone horn. You can get a regular horn sound simply by adding a low tone horn to the stock high tone. That will give you that nice dissonant tone that grabs attention but won't be a crazy loud ****-off-your-neighbors sound.

You can get a generic low tone at advance auto (or similar) for about $10-15. Install is easy. I did this install using the Fiamm Freeway Blaster hi and low tone. Again you can just add a low tone to the stock high and it will sound fine, I just happened to get both as a present.

-jack up front of car, place on stands for safety (never work under a car only held up with a jack)
-remove screws holding the left side under shield to the bumper/fender and bend it back out of the way.
-attach the new horn to the bracket it came with (ground one pin to the bracket)
-remove the nut holding the OEM horn on, connect the new bracket to the OEM horn's bolt and replace the nut.
-make a Y-splitter for power. At the base of the Y put a male spade connector, then run two lengths of wire (4-6" or so) to two female spade connectors.
-plug the male connector into the car's wiring, then plug the female connectors into each horn.

Viola you're done.

I'm actually visiting my father and he noted his whimpy horn last night (pretty sure I mentioned it when he bought the car) so I'll be doing this on his car soon as well.

 

So, no removing the front bumper? That would be great. The job is still too technical for me, but the college kid next door works on his car all the time. Maybe for a case of beer???

 

To expand on icspots post....



$17 @ AutoZone, but they can pretty easily be had at many other places.
I put the set on my wife's Vibe which had the current REAL whimpy Toyota horn on it.



That horn now resides on my lawn tractor.....

 

Assuming it's anything remotely like the 3 then you don't have to remove the bumper to install it. I actually installed mine without jacking the front of the car up and it was a huge PITA. Basically I could fit either my face and A hand under the bumper, or two hands but not both. So things that should have been simple required a little more fumbling to accomplish.

Removing the bumper cover will make the whole job just a little easier to deal with and really only takes 10 minutes or so. As to the job being technical it really isn't that bad. Pictured below is the little Y-connecter you need to make to split the power lead, and otherwise it's just a few bolts and screws. Still if you're not comfortable I'm sure you can find a college student somewhere willing to work for beer. If we lived closer I'd do it for you. Actually I'll likely be doing my father's today.

Thanks for the pics Richard, I was posting from a phone so picture links were a bit of a PITA. Here's a couple more blown up ones.


Here you can see the ground wire for the second horn connected to the bracket bolt. If you're using the stock horn then it doesn't have a ground connector, if you replace with another one then you'd just do this with both wires. My Freeway Blasters came with a ground wire for each horn.


Here's the little Y-connecter you need to make.

 

Or... the easier way:
