The modern stereo system

Wow... this stuff adds up fast.
Personally, as a half-deaf old fart who can't hear the person in the passenger seat screaming for dear life, the "concert hall experience" is a moot point.
In my D200 pickup I've got a cheap azz swapmeet FM convertor hooked to the stock AM radio. In another of my Darts I've got a head unit with remote in the trunk, and use a pair of decent wireless earbuds. Works for me and doesn't annoy everyone else.
