Hi so I have a 2004 infiniti g35 coupe and my speakers have not been playing music. Although, on occasions when I turn the car on i scroll through the volume from 0-30 then back down and it sometimes pops and starts working and once I set it at a volume, it stays at that volume and does not change throughout the duration of the drive. Sometimes the subwoofer works while the audio of the actual speakers do not as well. The head unit's display works perfectly fine as well.
