The horn on my Elite is rubbish.. think it's a single tone.. the one on my Vectra was excellent.. probably two tone... can the horn be upgraded?
I upgraded mine to twin tone easy to do.
It's one of the jobs I've been meaning to get around to on my Astra-J as the single horn is pathetic.
Unlike on the Vectra-C where the two horns were split and one mounted under each headlight, on the Astra-J I believe both horns are mounted on one bracket behind the bumper below the passenger headlight. Room is tight from what I gather, but it's plug and play as the connectors are the same.
You are correct
@Big Dave2 it's behind the bumper passenger but can get to it from the wheel-well or even if it's up in the air.
