Free Kicker active-style headphones with a purchase of $100+ of Kicker gear 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 Titanium-domed 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!

The Kicker KS525's are awesome when listening to rock. They have been very durable and the sound is crisp and clean. (Sounds better with my new amp). You get your money's worth out of them for sure, i would recommmend buying these.

PROS: Clean, Crisp sound, and Durable
CON: Features are limited (but still worth the money)

Put these in the rear of my dodge ram after I blew the MTX's. I did have them amped pretty good but now they're just powered by the kenwood head unit. Sound really goood either way. Dont throw too much bass to them amped or they will distort. Thats not a problem since I put my subs in. Overall excellent speaker for the price!

Sound great. Perfect fit in a 2002 Buick Century, front door panels. The tweeter doesn't protrude too much from the top of the cone so it should work well in most installs. 45W rms is more than any head unit is capable of producing so there's room for expansion. Been in love with kicker products for 10 years now.
