outlander 2007 rockfordfosgate
 

I have a 2007 outlander elegance with rockfordfosgate sound system. The volume for audio/satnav keeps dropping in and out intermittently. Sometimes the volumes just drops level to something you could barely hear.
I have opened front face panel and all cables seem to be secure with good connection.


I am now thinking it could be an amplifier issue or issue with the main rockforfosgate itself? Anyone have any ideas?
