Guys, the two speakers on the parcel shelf aren't working, are these standard on the VX Calais?
the VX Calais should have the premium system as standard and should have 2 x 8" subs on the rear parcel shelf. The sub amplifier is mounted on the left hand side of the boot and to access it you have to remove the carpet from the left hand side boot space and the amp is mounted behind the steel panel near the back seat.
