horn directions?

Ok guys I wana mount my K5s under my 91 toyota now I have alota work done to this truck its jacked up wid 38in mud tires and all I’m planin on buildin this truck for show nt play bt I can mount my horns in 1 place under my truck(where the spare went) bt the have to face fowards so the horns are open if they face backwards the middle horn is about a half inch from my reciever hitch will faceing them foward make them sound different or mess them up? Thanks I jus want to do it right the first time.

From what you have said I see no reason why you couldn’t face them forwards.
