Only if it "cooked" the circuit that it's on and any other circuits that might be related to it. On this car, the horn circuit also ties in (although indirectly) with the brake lights, keyless door lock control unit, cruise control. The dealer would really be "reaching" if he wants to deny you warranty repair on any of these other systems if they went out and you have a non-factory horn in place. I've had my dual horns on for over a year with periodic use with no problems. I upped the amps on the fuse as per "FAQ". If in doubt use a horn relay and an inline fuse.

 

Here's a link to an FAQ that I wrote on istalling Fiamm air horns. HTH
https://www.s2ki.com/faqs/showfaq.php?threadid=17409

 

I installed six fiamm air horns with two compressors in front of the radiator behind the grill.
Ran a separate line and 20 amp fuse. It was a little tough getting them all to fit.
Unbelievably loud and shrill. Sounds just like a diesel locomotive.
Really upsets some people. I plan to be very sparing with their use.

 

Dayum! When you hit the horn do birds fall out of the sky?

 

I'd be more concerned about the car stalling!

ROFLMAO!!
That was great! I love dry humor.

 

likewise I have a similar setup, 6 horns but on 3 compressors, each on a 20A circuit. And I like making soccer mom have a heart attack as she realizes that I, in fact, do exist on the highway beside her.

 

a member, Ray, has them, they are frikkin loud.

 

I have the FIAMM dual airhorns installed in my car and love them. They are definitely loud and will get the attention of everyone around. you can barely hear the stock Honda horn.
