Marco Tornado Car and Motorcycle Loud Air Horn

David Steinberg: I had my shop install it, so don't know how difficult the process was in a 2015 Miata.

The horn is (maybe) louder than the stock horn, but not as loud as I was hoping for.

Vaughn T. Hangartner: A decently loud car horn.

Is it as loud as an SD40-2 with a 5 chime Leslie Airchime bearing down on you at a railroad crossing? Nope. Sorta can't be. It's a set of 2 high tones. Considering the size of the diaphragms and the length of the trumpets, it's pretty evident it is not going to have a low tone. The construction appears decent, the plastic is of reasonable grade, the cast aluminium parts appear suitable.

Ease of install?

For me, it was no more challenging than installing a set of driving lamps. Have you installed a car stereo or amplifier, a set of mudflaps, door trim, window film or upgraded your headlamps? You should have the skills to install this horn.

If you're purchasing this with the thought you're going to get a garage to install it for you? Most mechanics/technicians will give you a CYA quote. Garages don't usually (or begrudgingly will) install 'unknown quantity' parts you bring in.

So, a sum-up;

Pretty loud.
High tone.
Reasonably easy to install.
Requires you know how to string 12vdc wiring.

The NCThe NC: I've just installed this in my vehicle and the output is excellent! It's definitely louder than stock. The most difficult part for me was to find a good mounting place for it. The detailed diagram on the back of the box showed exactly how it needs to be wired to your vehicle. On my vehicle, I followed the lower right diagram and used the following items:

1. This horn kit (relay included in box)
2. 12AWG wiring, 1 roll of red, 1 roll of black(don't want to confuse myself with + & -)
3. 12gauge ATC inline fuse holder here on Amazon

4. Six female spade connectors
5. One male spade connector(your vehicle may differ on this connection)
6. Three ring terminals
7. One 20amp fuse

These are the steps I took, follow at your own risk. First, mount the horn to the desired location. Then connect wires to the relay with the female spade connections according to the diagram. Connect the 87 wire to the new horn positive terminal with another female spade at the end. Connect the 86 wire to the original horn positive wire with a male spade connector (again, your...
