Kicker KS Series

Does a serious factory upgrade, with more muscle at an affordable price, sound too good to be true? What it sounds like are some of the loudest, clearest coaxials ever hidden behind a door on under a back deck.

Give factory sound a serious power injection with a KS-Series Coaxial Speaker upgrade. With added improvements on the woofers and tweaked tweeters, dropping them in where factory speakers were seems like a no-brainer. The curvilinear, gray woofer cones, Santoprene surround, and newly designed basket give KS Coaxials the extra brawn to deliver a smooth, rich sound at any volume.

The tweeters contain a stout neodymium magnet dipped in ferrofluid for maximum coolness, recreating highs that rival live performance. Give your system the upgrade that it deserves with Kicker KS!

  • A part that is fully functional but shows no sign of use outside of installation.
