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!

Great value, great product

Using as a replacement for factory 4" 79-93 Saab 900 dash speakers. They sound great, and don't flinch when I turn them up with my 55W/channel Sony head unit. Bass doesn't 'thump', but they're 4" speakers...(I don't know of any 4: speakers that "thump".) I plan to put a sub in my trunk and divert the low frequencies there eventually.

great sound from such a smll speaker.....gets LOUD!

Using these in a 3" to 4" PVC elbow w/ spacer speaker tube on my motorcycle with a Kenwood KAC-1502 running them. I have my iPod for music. Sounds great for a 4" speaker (even good bass for a 4" speaker). I put a port on the PVC as well with a plug I can put in/take out. Looks kind of gaudy up on the bars. But, the sound outweighs that in my opinion.
