Kicker designed their KS Series speakers to be a substantial upgrade from factory speakers or older, deteriorating aftermarket speakers. The 51KSC6904 6″×9″ speakers feature polypropylene woofers that provide a satisfying, natural sound, paired with 1″ silk dome tweeters that deliver smooth reproduction of your music’s vocal and instrumental details.
These speakers offer impressive performance even when powered by a factory radio, thanks to Kicker’s highly sensitive design that produces substantial volume from low-powered factory systems. If you’re not planning to swap out your factory radio or add an amplifier, these speakers will still deliver a noticeable improvement over your original speakers.
The 51KSC6904 speakers feature a low-profile design with reduced mounting depth and minimal tweeter protrusion, making them compatible with most factory locations. You can use the included grilles if you’re creating a new speaker location, or install these speakers behind your factory grilles or panels. The package also includes adapter brackets for various vehicle-specific applications and spacers that can be used to adjust the mounting depth.
