Alpine 4913 Adapter For Early CD Changers interconnexion.
This is a replica of the Alpine 4913 DIN and RCA adapter I made to order.
It is used to connect a newer M-Bus CD changer without RCA outputs to early Alpine units with RCA inputs (7288, 7390, 7294, 7909,...)
Can also be used to connect an early CD changer (5952, 5952S, 5959) to a late head unit without RCA inputs.
