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!

Great replacement
Great replacement 4" speaker. Didnt expect much from such a small speaker, but these are much better than I expected!

Good sound great value
Needed a stock size replacement for my 4Runner's in-dash speakers. These had the best materials for the price and I still like the way they sound for 4" speakers; They give about as much quality sound as you can expect for a speaker that size. Extremely easy to install, did it myself.

Big things DO come in small packages!!!
I purchased these speakers to replace the 4" speakers in my boat, thinking that I'd get my $'s worth if they lasted a couple of years in a marine environment. These speakers are phenomenal!! They are a perfect front stage speaker (w crystal clear highs) for a system with either a sub or larger rear speakers. I decided to isolate these speakers (hooked up to deck pwr) from my system to believe my ears and wow, they sounded like a 6 1/2" speakers!!! I wouldn't buy any other 4" speaker after owning these.

Very surprised!
I ordered these speakers because they were cheap and my front speakers were blown out. I wasen't really expecting to much. But i am VERY happy with them. The highs are amazing, and the mids sound good. And they get pretty loud to.
I've had them for about a year now, and the only thing is one of them started to crackle at high volume but stopped doing it recently. I think its because they got wet being where they are located in my door.
Overall I'm very happy with them, and would recommend them to anyone looking to replace their stock 4" Speakers.
