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 Kaladex-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!

Since I have only listened to the with a sub, I cannot tell the bass, but these Kickers definitely are clear, and are not that expensive, definitely recommend if youre stuck with needing 4x10s

January 18, 2011 4x10's Hard to find

I have a factory original 86 Pontiac Fiero GT with less than 3000 miles. The factory speakers in the dash had dried out and pulled away from the frame. I had great difficulty finding 4x10's and certainly difficult at a price I could afford. I was also concerned about the amount of ohms, not wanting to overload the original radio. I found Kickers to be right size, right sound, right price, right quality, and Sonic to be a fast, good company to deal with. I will definately use them again.
