03 and 04 G35's had a Technical Service Bulletin regarding the audio system circuit board. I would suggest calling your nearest dealer with your VIN number in hand and ask if the Circuit board has been replaced. If it has it could still be the issue. The radio unit itself could be bad too. I worked for an Infiniti dealer for 10 years and we replaced a lot of circuit boards, and quite a few radio units. On those vehicles, however the radio is not like the radio on most cars. The display is one part, connected to the console, behind that is the circuit board and behind the board is the radio, which is nothing more than a square silver box. More than likely this is going to be a dealer only repair as is the case with most of the newer Infiniti models.
See none of the speakers have sound, however the sub sounds scratchy the previous owner had a sub in the trunk but he sold it separately; and all the wiring is still intact. What should i do? Radio works fine by the way.
