So i'm about to buy a 2005 Volvo S80 2.5T AWD, and it has the stock head unit (not even sure which number it is). Did Volvo make a center speaker for this model S80? And if so, what other upgrades are required to make it work? (I'm assuming a different head unit and possibly an external amplifier?). I want to keep a stock setup, so basically I want to know what's the nicest factory Volvo setup I can install in this car, and any details I need to know about the install.
Thanks.
