Why Upgrade to Kicker CS Series Speakers?

Factory speakers are often limited by:

• Small magnets
• Lightweight construction
• Low power handling
• Minimal bass output

The Kicker CS Series addresses all of those shortcomings.

Key features include:

• 6×9-inch coaxial speaker design
• 150 Watts Peak Power
• Heavy-duty motor structure
• Extended Voice Coil (EVC) technology
• Polypropylene woofer cone
• PEI tweeter design
• Reduced mounting depth
• Factory replacement compatibility

The result is cleaner, louder sound with noticeably improved bass performance.

Designed for Stronger Bass Response

One of the biggest advantages of the Kicker CS Series is its focus on low-frequency performance.

The CS-Series delivers remarkable performance and ultra-clean bass, utilizing a heavy-duty motor/magnet structure with EVC (Extended Voice Coil) for even deeper lows.

Extended Voice Coil Technology (EVC)

Kicker utilizes Extended Voice Coil technology to improve:

• Cone control
• Low-frequency output
• Power handling
• Overall efficiency

The EVC design helps the speaker move more air, resulting in deeper and more controlled bass response.

For many listeners, this means hearing bass notes that factory speakers simply cannot reproduce.

No, it won’t replace a dedicated subwoofer.

But it will make your factory system sound dramatically fuller.

Heavy-Duty Motor and Magnet Structure

The CS Series utilizes a larger motor assembly than most OEM speakers.

Benefits include:

• Improved efficiency
• Better speaker control
• Reduced distortion
• Greater dynamic response

This allows the speaker to maintain clarity while producing stronger output.

Whether you’re listening to classic rock, country, EDM, or hip-hop, the difference is immediately noticeable.

Polypropylene Woofer Construction

The woofer cone is built from rigid polypropylene material.

Compared to factory paper cones, polypropylene provides:

• Better durability
• Moisture resistance
• Improved bass response
• Reduced cone flex

This construction helps maintain consistent sound quality for years of daily use.

Especially important in vehicles exposed to:

• Heat
• Humidity
• Cold weather
• Daily commuting abuse

By drastically reducing the mounting depth, CS-Series Coaxial and Three-Method Speakers will are compatible in just about each make and model of auto at the road lately.
The very best upgrade out of your factory sound, a stamped-steel framework supports a rigid polypropylene cone and nil-protrusion PEI tweeters.
UV-treated poly-foam surround resists heat or direct sunlight
Neodymium tweeter magnets allow for increased volume in high frequencies

PEI Tweeter Technology

The CS Series features:

Zero-Protrusion PEI Tweeters

These tweeters provide:

• Crisp high frequencies
• Improved vocal detail
• Better instrument separation
• Enhanced overall clarity

The low-profile design also improves fitment in factory locations where space can be limited.

Designed to Fit More Vehicles

One of the most frustrating aspects of speaker upgrades can be installation.

Kicker specifically engineered the CS Series with:

Reduced Mounting Depth

Benefits include:

• Easier installation
• Improved factory compatibility
• Fewer clearance issues
• Broader vehicle fitment

According to Kicker, the CS Series is designed to fit nearly every make and model currently on the road.

That means less cutting, less fabrication, and fewer surprises during installation.

Which is always appreciated when you’re halfway through a Saturday garage project.
