I'm sure it has nothing to do with your ignition system or grounding. I had
2 cars (1 chev, 1 older BMW) that had the same problem. There is a hot (power) wire laying across or too close to your speaker wires, after time the insulation breaks down or the caseing is damaged and "white noise" is picked up by the speaker wire. And it usually fluctuates with engine speed, as the alternator changes output. I did alot of research on my BMW, as this was the first car it happened to, and found that it is a common problem for older bimmers. So, I could imagine it could be the same problem.
