3.5" speakers are often used in the upper dash corners of both modern and classic cars. 3.5" coaxial speakers will generally act as a tweeter while still providing minimal mid-bass response. Most do not come with speaker grilles as they will remain behind an original speaker grille or
factory panel. With 3.5" speakers, it is important to note the tweeter protrusion as some speakers will not fit behind factory grilles because the tweeter sticks out to car.
