Electric "Highway" Horns
After literally being run off the road by the driver of a fully loaded pick-up truck who didn't even know I was there and couldn't hear my puny little Miata meep-meep horn, I decided to fix THAT problem.
I bought a set of Wolo Model 125 Dominator Electric Horns. These horns produce up to 125 db. and while they are usually found on boats, they will work just fine on my Miata.
Installing the Roadmaster towing baseplate positioned a square crossbar running side to side across the front end. This crossbar (pictured above the left horn trumpet) made an ideal platform from which to hang the dual horns..
The horn trumpets are pointed slightly rearward so that rain blowing in the grille will not flow into the horn trumpets. Remember, these horns are electric and there is no air to blow water and debris out.
I installed 2 horn relays.
#1) When the
ignition is OFF, this sends power directly from the battery (not through
the rest of the electrical system) to the stock
meep-meep horn when the steering wheel horn button
is pushed. This is the default state of the Miata horn.
Wiring the horns this way the keeps the door lock confirmation beep from blowing us away or waking the neighbors.
The chrome horns
are visible through the grille opening.
They are not the fog horn on the Queen Mary, but they are VERY LOUD!
Miata has gone from "Can you hear me now?"
