My first instinct would be to rip out the factory head unit and
replace it with something decent,

Make sure it's compatible with any out board amplification - as the system
has a sub it may not be straightforward. I'd go with an Alpine if you're
using on board amps. Blaupunkts are good but the built in amps are weedy.

Some manufacturers have got premium audio right - Lexus, Rover (the 75 with
the Alpine / Harman system was great), Volvo (Dynaudio speakers, also done
the new Passat).

sun and you and me and all the stars that we can see, / Are moving at a
million miles a day / In an outer spiral arm, at 40,000 miles an hour,
/ Of the galaxy we call the Milky Way.
