If you have a car subwoofer connected to a amp and its making a buzzing or humming static sound, this is because it's not properly grounded to the cars chassis. This is mainly because there is paint between the metal and the ground wire causing electrical problems.
1) Power off the car's ignition so there is no power going into the amp.
2) Find your grounding location.
3) Unbolt the terminal loop from the mounted area.
4) Get some sandpaper and file down the metal surface until you can see bear metal.
5) Reconnect the ground wire.
