Anyone know how different is the HK Premium and Base System? I read somewhere the Base System is also made by HK. Is mainly 4 more speakers? Sorry I know this comes across as really dumb question. Volvo really does not provide much detail on the base audio system.
Notes From 2019 Brochure:
Base System:
High Performance audio system (330W,10 speakers)
