Many vehicles today take the 5×7 Speakers / 6×8 size, and this size has been around for a long time. Both a 5×7 speaker and a 6×8 size have the same basket fitment, but the 6×8 is a 5×7 that has extra screw mounting options for certain vehicles that list a “6×8” as a factory fit. If you own a Ford, Lincoln, Mazda, or Mercury, chances are there’s a 5×7/6×8 size somewhere in your vehicle. Ford and its sister companies Lincoln and Mercury have used the 5×7 in their vehicles since the 1960’s. Early Ford’s came with a single 5×7/6×8 sized speaker in the dash. Ford continued with this size since then, and still uses it in their vehicles today, both up front and in back. Most 5×7 speakers come in a coaxial or three way version, although component set ups are available with separate tweeters. This type of speaker provides good mid-bass for its size, and offers nice clarity and vocals. Typically, a factory 6×8 speakers has a paper cone and foam surround, causing it to dry rot and wear out within a few years of the vehicle being new. Our quality aftermarket car speakers use high quality material like poly cones and rubber surrounds.
