DIY car horn: Installed OEM VW dual horns on my Hyundai Getz

I have retained the factory Hyundai horn, creating a loud/blaring 3 tone effect...

BHPian tooSavvy recently shared this with other enthusiasts.

The Hyundai horn is a little bit 'meek', as a toot!!

I bought, on eBay, a set of Fiamm VW original fitment twin-tone horns (sourced from a breaker in Lithuania!).

The horns are fitted directly under the 'slam panel' and emit directly out the grille - above the rad/a/c condenser.

I have retained the factory Hyundai horn, creating a loud/blaring 3 tone effect... Very raucous

I have picked up the power from the socket of the Horn Relay and have an inline 10A blade fuse.

I have made a Tube 'short' so you can all hear the horns in Action

Here's what BHPian alphamike_1612 had to say on the matter:

By this, I assume you have taken power from the wire that leads via the fuse panel to the horn relay. Please ensure that the fuse for the horn inside the fuse panel is rated higher than the current required for both horns together margin(20%). ie.) I would expect it to be 20A (since you have used a 10 A fuse for the new horns and I expect the stock one to at least use 5A, leaving us with a safety margin of 5A.)

If it is not 20A, do not change it before confirming the wires will be able to handle 20A.

If not, I would suggest adding a new relay from the battery and using a wire to connect the 2 switching pins of the relays together.

Why do this?

Over time, the use of a higher current than intended through wires that are designed for lower currents might lead to heating and melting of the wires and chances of a short.

A fuse should stop a catastrophic accident, but replacing the harness might become a costly affair.

Since horns aren't a constant source of power draw (unlike headlights), this should take a long, long time to happen, but I believe in erring on the side of caution.

Cheers.

P.S. - I am not a professional, so if the idea is dumb, I'm all ears to listen.

Thank you for taking the time to comment... I cannot believe there are over 300 views on my YouTube !!

Agreed on 'power/heat in loom' but, again, you say short bursts...

It IS fairly outrageous, on that Blast!!

Kindest regards
