KICKER CS Series 6.5 in 300W Coaxial Car Speakers - Clear Bass

In this review the KICKER CS Series 6.5 in coaxial speaker pair is judged on value and sound for everyday car audio upgrades. The bottom line: these renewed speakers are aimed at drivers who want noticeably cleaner midrange and punchy low-end without replacing their head unit or spending on component systems. The single biggest reason to buy is the blend of a polypropylene cone, PEI dome tweeter and KICKER's EVC technology, which together deliver clarity and usable bass from a compact 6.5 in package that fits most factory locations.

Key Features

• 6.5 in coaxial pair: A matched left/right pair designed to fit most car speaker openings for an easy swap-in upgrade.
• 300 watt peak power: Handles high-volume listening with a 300 watt max and a practical 100 watt RMS rating for sustained output.
• EVC technology: Enhances woofer excursion so the cone delivers tighter, more controlled bass from a small 6.5 in driver.
• PEI dome tweeters: 0.5 in PEI tweeters provide crisp high-frequency detail and use neodymium magnets to keep highs clear at louder levels.
• Polypropylene cone and UV surround: Durable cone material and UV-treated polyester surround resist heat and sunlight in a car environment.
• Broad frequency range: Covers roughly 40 to 20,000 Hz to reproduce low-end punch and upper-frequency detail for modern music.

Who It's For

This pair is best for drivers upgrading factory door speakers who want improved clarity and bass without installing separate amplifiers or component crossovers. It suits commuters, weekend drivers and anyone who prefers a straightforward plug-and-play replacement that fits common mounting depths.

People who need extreme bass extension, custom component systems, or precise sound staging for audiophile setups should look elsewhere; this is a coaxial solution optimized for convenience and balanced everyday performance rather than ultimate SPL or room-like imaging.

Pros & Cons

Pros

• Clear midrange and defined bass thanks to the polypropylene cone and EVC technology.
• PEI dome tweeters with neodymium magnets deliver articulate high frequencies.
• Durable construction with UV-treated surround suitable for automotive environments.

Cons

• As a renewed product, cosmetic wear is possible and the package is not a component system for the most demanding listeners.
• Top mount depth is shallow but bottom mount depth requires checking some factory locations before purchase.

Frequently Asked Questions

Are these speakers easy to install?
Yes. They are designed to fit common factory cutouts and typically swap into existing mounts with basic tools, though you should confirm depth measurements first.

Do these come with a warranty?
Yes. The renewed product includes a 1-year manufacturer warranty that covers functional defects.

Will they need an external amplifier?
Not necessarily. They can run from many factory head units at reasonable volume, but an external amp will improve dynamic headroom and loudness if desired.
