Product Research
Features
Woofer Cones: The Kicker KS Series speakers feature durable polypropylene woofer cones, resistant to moisture and the temperature extremes found in automotive applications.
Dome Tweeters: The ¾” silk dome tweeters provide a smooth high frequency response with a wide dispersion pattern. The tweeters have neodymium magnets.
Mounting: The speaker baskets have multiple mounting holes and are designed to fit a standard 3-hole 6½” applications and Ford’s 4-hole 6½” application. With the extended mounting “ears” around the perimeter of the frame, they also fit many 6¾” applications, but a speaker baffle should be used to seal the inner ring of screw holes. Kicker also makes a dedicated 6¾” speaker in this series (item number 20651KSC67) that is often a better fit for those applications. Adapter brackets are also included that are compatible with other factory speaker applications. Please enter your vehicle information to confirm fit.
