Kicker 51KSC504 5inch KS Coaxial Speakers

Potent Performance

KICKER KS-Series Speakers let you play at concert-like volume, yet maintain the smoothness and subtlety to please even the most selective ear. Internally dampened polypropylene cones and durable rubber surrounds assist the woofers in creating precise midrange and midbass, while high-quality silk-dome tweeters deliver natural, detailed highs.

With less than a 2-inch mounting depth and one millimeter of tweeter protrusion, the KSC50 is a perfect fit in almost every vehicle on the road today. They work best with 15 to 75 watts of recommended power. See below for more details.
