Door Speaker
For the front door speaker, two types of speakers, 16 cm paper cone speaker < vehicles with 4 speakers, 6 speakers > and PP (polypropylene) cone speaker < Rockford Fosgate® premium sound system >, are available. For the rear door speaker, two types of speakers, 16 cm paper cone speaker < Vehicles with 4 speakers, 6 speakers > and PP (polypropylene) cone 2-way coaxial speaker < Vehicles with 9 speakers (Rockford Fosgate® premium sound system) >, are available. Compared to the paper cone speakers, the PP (polypropylene) cone speakers can playback crisper bass. The door opening of the vehicles with 9 speaker (Rockford Fosgate® premium sound system) is blocked by using the sheet metal cover and the urethane integrated resin sheet (resin cover and water proof film) to make the door into a speaker box, thus improving the sound quality. As an advantage of the sheet metal cover, the rigidity of the areas around the speaker has been increased, and the higher sound pressure, suppression of high harmonic, and suppression of dumping are achieved to improve sound quality.
The one-touch installable speaker (with 3 tabs, fixed by rotating) has been adopted to improve serviceability.
