One common cause of speaker whine comes from the vehicle’s alternator. If the noise changes in pitch or intensity when the engine RPM changes, it’s probably some type of engine noise, and interference from the alternator output is a likely source.
In case your car already has an engine cover or shield, you can consider making it soundproof by adding a layer of sound damping material. Installing underbody covering: A 100-150 micron thick underbody coating can reduce the noise from the road and reduce the engine noise to some extent as well.
