Hey Darren...
It easy mate... dont take the plastic covers off.... install the speakers from under the shelf and keep a stelf look, and it saves you from removing the shelf, seats and side panels have to come off. I think the screws are still there mate.
Don't install splits in the rear, just do 2ways ok. Because splits are for front stage only.
Don't forget what I did for a job for 6 yrs bro.
Call me if ya need some help k

P.S
Did I tell you there are 2 alarms in your car....lol
Just under the bonnet release there is a chrome switch flip it and then you can use the key alarm aswell.
