A great YouTube show-and-tell of "One of the most advanced car cassette players ever made," by Sathyan Thambirajah about the Kenwood car cassette player KRC999 mark II. Perfect musical selection, too.
"This is the 1988 mark II version with fluorescent graphic equalizer," Thambirajah says. "I was lucky enough to aquire this in Hong Kong in 1992. It is a component unit which requires individual front and rear amps to drive the speakers."
