I've got a Sony 6 cd changer mounted under the seat of my '93 that plays through the FM band on my radio. The remote is mounted on the dash and it operates with a small hand held remote. I have 2 cassets so I can load up for a long trip. I can reach it while driving to change cassets. I also upgranded both the door and rear speakers. I love it and can't remember the last time I listened to the radio.
Happy Trails
