KICKER CSC46 4x6-In Coaxial Speakers (Pair) - Clean Bass Upgrade

In this review of the KICKER CSC46 4x6-in coaxial speakers, the bottom line is simple: these are a practical, high-value upgrade for drivers who want noticeably better midrange clarity and tighter bass without complicated installation. The reviewer found the CS-Series design focuses on deep lows from an extended voice coil and a reduced mounting depth that fits in many factory locations, making these speakers a solid choice when replacing worn stock units or modest factory systems. Expect improved sound quality and an easy fit in most vehicles.

Key Features

• Extended Voice Coil: EVC motor and magnet structure delivers deeper, cleaner bass than typical factory speakers.
• Shallow Mounting Depth: Reduced depth allows these coaxials to fit in a wide range of vehicles without custom adapters.
• Rigid Cone Construction: A stamped-steel basket and polypropylene cone provide stable midrange performance and reliable durability.
• Durable Surround: UV-treated poly-foam surround resists heat and sun exposure for longer life in car environments.
• Neodymium Tweeters: PEI tweeters with neodymium magnets increase high-frequency output and clarity at higher volumes.

Who It's For

The KICKER CSC46 pair is aimed at drivers replacing factory 4x6-in speakers who want a clear improvement in sound without modifying speaker mounts. It is especially suitable for people who value stronger midrange and tighter bass from a coaxial speaker and need a set that installs cleanly in compact mounting locations.

These speakers are less appropriate for audiophiles seeking high-end component systems or those who want extreme low-frequency output from subwoofers; if maximum SPL or very deep bass extension is the goal, a dedicated sub and component setup would be a better match.

Pros & Cons

Pros

• Noticeably better sound quality and midrange definition compared with many stock speakers.
• Shallow mounting depth and common screw hole alignment make installation straightforward for many vehicles.
• Durable materials - polypropylene cone, stamped-steel frame and UV-treated surround - for longevity in car environments.

Cons

• Not a substitute for dedicated component systems or a subwoofer if very deep, powerful bass is required.
• Some users reported isolated issues with high-volume distortion or failure, so long-term reliability can vary by use and installation.

Our Verdict

The KICKER CSC46 4x6-in coaxial speakers are a practical, cost-effective upgrade for most drivers who want clearer mids and improved bass from a direct-fit replacement. With durable materials, a shallow mount, and focused design choices like EVC and neodymium tweeters, they offer strong value for factory-replacement buyers, while those seeking extreme bass or audiophile component setups should look elsewhere.
