Customer Question

This is in reference to an Alpine CDA-9884. Problems began with intermittent failure of all speakers except the right rear. The problem eventually progressed to only the right rear speaker working except when it rained (weird huh?). When the other speakers last worked, it was a rainy day and I noticed that when I jiggled the main control knob, the function of the other speakers went in and out. It has been several weeks now since any of the speakers except the right rear worked? Any advice?

Hi and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...
Initially, can the volume of the other speakers be controlled/adjusted using the remote control? Do all other functions of the rotary encoder work as expected? Is the speaker problems commonly observed in AM, FM, CD and any/all others sources including when used with an iPod?
Still, the described symptom appears to be a hardware issue. Best proposed approach is to first check the status of wiring and the speakers themselves (even if just to eliminate them as potential suspects).
Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multimeter and even perhaps a soldering iron?
