    Even in 2004,24 year later. The installation of midrange and tweeter still use the same old way, that is because the manufacture of the car neither the speaker company not consider about customer's need. Instead, the car manufacture had spot on the popularity in the speaker market then design the speaker's mounting space according to the popular type of the speakers. And the speaker makers in contrast had intend to design the speakers to macth the speaker's mounting space. So no one think about select a new position to install the midrange and tweeter that meet with customer's need, and how to produce a matching speaker to install in that position.

    Today Top panel Speaker has been born to be the speaker that has the best way to suited with customer's need.
