Infinity gold radio seems to work but cant get any sound

Did u check the fuses for radio and the amp itself, that's the most common thing when changing a radio or amp with a vehicle with an amp in it

Make sure the speakers are matched to the system

I have the 1995 version and have had the same problem. For some reason, I would be driving down the road and then all of a sudden the sound would cut off. No indications on the radio. For the longest time I drove around without music, then one day I turn the volume up and it worked fine, the unit was resetting itself to the lowest volume setting for some reason.

I pulled the unit, cleaned and tightened all connectors; opened the radio up and resoldered the connection on the power board; and cleaned the connection to the antenna. I don't know which item fixed the problem because I did them all at the same time, but it worked, and so far the problem hasn't returned.

im having a similar problem with my VW passat but only with the sound. in your car somewhere there should be a 'convenience computer' or what runs all the electronics such as power windows and radio and so on. if that gets wet you will definitely have a problem with your power accessorizes in the car

lay out new speaker wires and that way bypass the amp altogather Kenwood radios have power to move speakers without an amp

sounds like a fault in the control panel. Either burnt out capacitor, ad relay, or shorted wire.

alot of the radio will interchange the best way to know is to check the connectors on back of both radio's. they also sell connectors witch allows you to switch them.

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. 

I had the same thing happen. Any resolution?
