15A is the right one

quick question!

Why does my nc2 have 2 horns?
every other car iv ever owned only had the one!

My experience is that 99% of ‘modern’ cars have two, even the Caterham has always had 2. It may be something to do with having two different ‘pitches’ so as to cover more of the populations hearing abilities but that is just my simplistic hypothesis.

The Nautilus horn in 12v mode pulls 19A according to the spec details so the standard relay should be ok as it’s rated at 30 to 40A, not sure about the wiring though.
