Radio alternators[edit]

The largest offender of noise in the car audio atmosphere is alternator whine. Alternator whine is a result of a change in electrical potential (voltage) involving two factors. It's always caused by a ground relationship that's lower than perfect.

22mm socket (24mm on later model with hex crucial). Never jam a screwdriver to maintain the pulley from rotating: chances are you'll hurt the stator windings.
