Description


Kicker brand icon

Authorized dealer

Kicker 51KSC6504

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 KSC650 is a perfect fit in almost every vehicle on the road today. They work best with 15 to 100 watts of recommended power.

More than just a factory speaker upgrade.

The following review is for 51KSC6504, which is a part of the bundle you are viewing.

I replaced an older version of the KS 6.5 coax with the new ones. The new ones are in a different class altogether. They sound as good or better than other brands that cost almost double. They come to life with an amp and can fit anywhere.
