I should think you could, but honestly, I think the sound system in the saloon is probably slightly better. I mean, you've got more going on on the back parcel shelf right? Two subs or something. We've just got s 6" sub mounted in the side panel of the boot. It's not as groovy as it sounds. I mean the system in the 7th gen exec is awesome, but I doubt the tourer's better than the saloon. Maybe equal to, but at a guess, I'd say probably slightly inferior as there's less going on in the back of the car.
