The original Notes had a nice audible speaker but from the Mk2 onwards the speaker is buried somewhere in the back. I believe that Nissan can supply and fit (for a lot of money) an extra speaker that you can actually hear...what a con!
ideally you need to look at the unit its self i think you find its a piezosounder rather than a speaker you then need to work out what thespec's ofthe one inthe unit is
(voltage/resistance ect)Edited by: flash22
Careful with the Maplin piezo sounders as VERY similar part numbers have widely different input voltages.
If you can visit a local branch the <strike>geeks</strike> enthusiasts who work there are invariably very helpful.
