Funny, you said that. I have 3 amplifiers and speakers / subs.
I don't think its to do with additional strain on the electrical system of the car.
Its more to do with contamination in the oil or high mileages cars.
I have added UV chemical in my oil to check any oil leaks but ended up having this issue.
Is your car on high mileages?
