I think this may be related to my aftermarket radio, I'll explain that below after my description.
After starting the engine theses past two weeks, there will be a whine coming from the subwoofer that will last for about 10-20 seconds then die off. I will also hear a subtle pop feedback from applying pressure to the brake pedal. Is this sound like an alternator issue or maybe because of the story below?
I swapped out my 6 disc CD headunit about two years ago and ever since then, I could never get rid of the start up and shut off pop from the subwoofer. I tried two 12v to 5v converters and neither one stopped it. Tried running the grounds all the way to the chassis ground in the engine bay also, but no luck. I think it has to do with the all-in-one Crux steering wheel control/radio wire harness still letting 12v go out somewhere. I bought the metra harness, a different steering wheel controller and another 5v converter and will swap it all out this weekend to see what happens.
