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!

Indecisive? Buy them!

First impression, good packaging, everything from this site is. Tearing open the box full of packing peanuts reveals the gems. Standard kicker quality, everything basic included to install. If you don't have a mounting solution, you will probably need more screws than provided. (Wire connectors are included) Once installed the system is very powerful, I haven't seen any other speaker with the same power for the price. Paired up with my Kicker 6x9s, they will hurt the ears at high volume without haptic feedback, and provide enough bass to go without a subwoofer, at least for some. 10/10 would buy again, very cheap 3 year warranty is offered, BUY IT it's good if you're constantly playing at high volume. No matter the product, 3 years of hard abuse will have anything worn down. 30 days and the speakers are still running like new. Can't really think of any negatives... Buy it!

Kicker's name says it all

I bought these along with some 6x9 kickers for the rear. I usually just fade about 70% of the sound to the back because of the acoustics in my car. But when I messed with the eq settings, I have to say these speakers are good. You can run just these and still have that thump that kicker seems to always have. I would recommend these door speakers to anyone.

Pretty Solid Speakers

Great sound, made the mistake of turning them up too loud while i didn't have my back speakers on and blew one of them slightly. But they are great all around, solid bass, clear highs. No complaints!

Great value

These speakers sound great in my S10. I have them pushed by a 65w RMS per channel Kenwood amp. And they get loud and clear and definitely keep up with my 2 10" Memphis subs. Great Speakers!!!

I spent 3 weeks researching 6.5" speakers for my ridgeline truck. I checked various websites and read reviews also watched several youtube videos on different products. I can say that these speakers do what they say they will do. The clarity i have with these speakers met all of my expectations. I have the components also for the front. I did buy an amp to go with this item (diamond300) i got that from my installer even though i had the kicker amp in mind. I have a pioneer nav z120 and all i have to do is turn the volume up to 20 (goes to 40) to rock out!! And just to let you know for the sub in my truck i bought an 8 inch shallow by pioneer which suits all of my bass needs. It will surprise you!!! Im satisfied!

Loud and clear sound but when playing something with a lot of bass they pop, and distort like crazy. would recommend to get a crossover to remove base frequencies.
