Question about Sony CDX-646 10-Disc CD Changer

1 Answer

Sound only coming from one side


I have recently purchased a car which has a Sony CDX-646 10-Disc CD Changer installed. When I play CDs from the changer unit, the sound only comes out of the left-hand speakers. I know that the speakers themselves are OK as when I use the tuner on the head unit, the sound comes out of all the speakers. I have checked to make sure the wires in the changer unit are pushing firmly in and they are.

Any ideas?

Appreciate your help.

Re: Sound only coming from one side

You should have 3 leads going into you multi changer, two rca's and one bus lead. power up the unit and remove the first rca cable if the music goes off unplug the second rca and plug the first rca where the second was plugged in, if the music comes back on then the multiloader is working fine and you need to check the radio controller and its connections
