Hello all. I did a search for this type of issue but have not found anything. Here is my issue:
I have a 2005 Infiniti FX35 AWD with 82,xxx miles. It has the factory Bose stereo system with stereo/CD changer/cassette. My wife and I purchased the car at 61,000 miles and are in love with it. While there are a few minor issues, there is one that completely stumps me. Ever since purchasing the car, there has been a spiratic popping sound (like static discharge) coming from a speaker every so often. It comes through one speaker at a time, has occurred in every speaker including the subwoofers, occurs while the stereo is either on, off, or playing any of the media types including the radio, and cannot be duplicated. The car is completely stock and has never been altered that I can see or otherwise. I have removed the amplifier from the vehicle and ensured proper continuity for the ground circuits and grounding of the amplifier frame. I have removed the head unit and ensured proper ground continuity from the head unit to the amplifier and no shorts between the amplifier and the head unit. I have removed, cleaned, applied electrical grease, and replaced all of the grounds in the engine bay. I have done a tune-up with factory NGK spark plugs and lubricated the spark plug coil boots with electrical grease.
Each time I go hunting for this issue and I disconnect the amplifier, the sound does not occur for the first day, and then begins to occur once more. To me, it sounds like a capacitor or transistor in the amplifier letting go of its charge, but I cannot prove this and I am not an electrical engineer capable of diagnosing circuit boards and components.
I should say that I went through school to receive my bachelor's degree in automotive service and graduated in 2007. From there, I worked for 3 different dealerships specializing in electrical diagnostics and engine diagnosis before being laid off and starting my own side-business while going back to college for a better paying job. I have received my ASE certifications in all 8 areas and received my L1 certification in advanced drivability diagnostics. So, I am no slum or dumbie when it comes to electrical issues. I am not looking for guesses, I am looking for recommendations with solid reasoning behind them, or personal experience with resolutions. Thank you in advance.
I am hoping that someone out there can point me in the right direction here or share an experience with this issue. I would appreciate any help. Thank you again!
