| One is the active cross overs which gives a | | | | A link to the ground should be made to the car's |

| passive cross over which is low adjustable and | | | | The low pass filter of the cross over can be set |

| There are few steps with which the question can | | | | through. This kind of filter setting is essential for |

| The first step in this task is to choose a location | | | | The cross overs are adjusted based on the music |
