I am still using the OEM speakers that come with the car. This OEM speaker sound so narrow and emphasis only at the bass. This speaker location is at the door panel and the sound from it is just like coming from the bellow of the dashboard.
That is why I want to add the new tweeter above the door panel. This tweeter will makes the sound more fuller by adding the high frequency which the OEM speaker cannot do. So here it is, the tweeter unit that using Vifa D26NC driver.
