Seeking advice....have had several Nautilus / Stebel units under the beak for years (Nippy Norman Part WUN 44720-002), a lot louder than stock horn but only lasts about 6-10 months before rain, road grime and poor quality seem to get the better of it, inevitably killing it off.........have been advised the Denali SoundBomb is NOT a good fit........ also have a pair of FIAMM AM80S Luxe in a box , would they do the trick? Looking for something with a proper sound, neat fit, CANBUS compatible, that will last longer than 6 months......suggestions very welcome ....thanks...
