Im installing a Pioneer am/fm/cassette with seperate CD player that sends its FM signal thru the antenna wire connection to the radio. I will put the CDplayer in the trunk or under the seat, it has a cassette that holds 6 cds. Not sure where I will mount the am/fm/cassette yet but the CD player has remote to operate it. My mp3 player also works by FM signal to the radio to play mp3s. So now I can run cassettes tapes or cds or am/fm with nice speakers.

I got all this stuff on ebay for under $100.
My standard am/fm flip face radio has only one speaker in the dash, its horrible but works. This will be a welcome addition with rear speakers for a change.
