When the Bose system was ordered ex-works, the rear seats were deleted, so may be it's not compatible with seats?

I know that if you haven't got seats you get a deck with a lid in it where the right hand rear seat base would otherwise be: there are details in the owner's manual.

The stock system is designed and made by Bose anyway, isn't it? Mine is fantastic with the Audio 30 head unit and fibre optic CD changer. I gather it is separately amped (the amp should be under the back seat). I find the sound amazingly clear and well separated and atmospheric and capable of playing at loud volumes.
