A guy in a car audio shop told me that the speakers in my 1998
Renault Safrane should be replaced due to their age. They do sound a
bit muffled but I thought that was the Renault style. The sole
previous owner hardly used the music.

Speakers are mechanical devices so will change characteristics over time,
dash and shelf speakers will be affected more so due to the sunlight .
