KICKER CS-Series 3.5" Coaxial Car Speakers (Pair) — 4Ω, Shallow Mount, 40W RMS

These are compact 3.5-inch KICKER CS-Series coaxial car speakers built to replace factory units and deliver clearer highs and balanced mids in tight installations.

Designed for vehicles with limited mounting space, the KICKER 46CSC354 (CSC35) pair combines a polypropylene woofer, UV-treated surround, and 1/2" PEI balanced-dome tweeters to upgrade sound quality without major modification. With a shallow 1-11/16" mounting depth and a 4-ohm impedance, they are optimized for both factory stereos and many aftermarket head units that need a compact, reliable speaker solution.

How do these small speakers improve my car audio?

Although compact, the CSC35 speakers are engineered to deliver clearer highs and natural midrange compared with many stock speakers. The balanced-dome tweeter handles detailed treble while the polypropylene woofer maintains controlled mid response, producing fuller sound from a small driver.

• Half-inch PEI tweeters for crisp, distortion-resistant highs
• Polypropylene woofer cone for balanced midrange clarity
• 40W RMS power handling for consistent, real-world output

Will they fit my vehicle and how difficult is installation?

The CSC35 speakers are made for tight spaces with a shallow mounting depth of 1-11/16", so they fit many factory locations where larger speakers won’t. Installation is straightforward for anyone comfortable removing door panels or kick panels; adapters or spacer rings may be needed for some mounting patterns.

• Shallow 1-11/16" mounting depth fits tight factory openings
• Standard 3.5" diameter matches common compact speaker cutouts
• Simple wiring and bolt/screw mounting for fast replacement

How much power can these speakers handle and what source works best?

The pair handles 40W RMS and 120W peak, which supports louder listening than many stock speakers while avoiding overdrive from typical factory head units. They pair well with factory or moderate-power aftermarket receivers; for higher output consider adding a small amplifier tuned to the speakers’ power and impedance.

• 40W RMS / 120W peak for dependable performance
• 4-ohm impedance compatible with most car stereos
• Ideal with stock head units or entry-level amplifiers for extra punch

Are these speakers durable enough for daily driving?

KICKER built the CSC35 with longevity in mind: a polypropylene cone resists moisture and a UV-treated surround reduces weathering from sun exposure. The small footprint and robust materials make them a reliable option for everyday use in doors, dash locations, or other interior mounting points.

• Polypropylene cone resists moisture and retains shape over time
• UV-treated surround protects against cracking and fading
• Balanced tweeter design minimizes distortion at typical listening volumes

Who is this for? The KICKER 46CSC354 CSC35 pair is aimed at drivers who need a compact speaker upgrade to replace factory units without major modifications. It’s best for owners of older cars with small factory openings, riders seeking clearer treble and better mids from a stock head unit, or anyone installing speakers in tight dash or door locations who still wants reliable, long-lasting components.
