Product Description

Elevate your driving experience with the Kicker KSC650 6.5″ KS-Series Coaxial Speakers, engineered for precision, detail, and durability. These premium coaxials deliver 100W RMS (300W peak) of concert-quality sound while maintaining smooth, natural highs and tight midbass.

Built with internally dampened polypropylene cones and tough rubber surrounds, the woofers provide accurate midrange and midbass, while silk-dome tweeters deliver natural, refined highs for a balanced soundstage. The neodymium tweeter magnets allow increased clarity without distortion, even at high volumes.

With a slim design and less than 2-inch mounting depth, the KSC650 is a perfect fit in nearly any vehicle. Zero to minimal tweeter protrusion ensures they tuck cleanly behind factory grilles, while the included mesh grilles provide extra protection if desired.

For audiophiles seeking smooth response and high power handling, the Kicker KSC650 6.5″ KS-Series Coaxial Speakers are the perfect upgrade for accuracy, power, and reliability.
