Kicker 47KSC504 KS Series 5.25" 2-Way Coaxial Car Speakers

Kicker 47KSC504 KS Series 5.25" 2-Way Coaxial Car Speakers

The Kicker 47KSC504 brings serious sound performance into a sleek 5.25-inch design that fits almost any vehicle on the road today. If your factory speakers feel flat or lifeless, this upgrade hits differently. These KS-Series coaxial speakers are built to deliver accurate audio, extended frequency response, and smooth highs without taking up precious space.

With a thin-mount design and less than a 2-inch mounting depth, they slide neatly behind factory grilles. It’s like giving your car’s sound system a clean, powerful voice without changing its appearance.

Concert-Level Volume Without Harshness

Ever turned up your music only to be punished by sharp highs and muddy bass? That’s where the Kicker 47KSC504 stands out. These speakers are designed to handle high power while keeping everything smooth and balanced.

They work best with 15 to 75 watts of recommended RMS power, offering the flexibility to pair with a wide range of systems. With 90 dB sensitivity and a 4-ohm rated impedance, you get impressive output without straining your setup. Whether you're cruising down the highway or stuck in traffic, the sound stays clean and controlled.

Premium Materials for Precision Audio

Great sound starts with smart engineering. The Kicker 47KSC504 uses internally dampened polypropylene woofer cones combined with tough rubber surrounds. The result? Precise midrange and tight midbass that doesn’t distort when you push the volume.

On the high end, you get a ¾-inch silk-dome tweeter powered by a neodymium magnet. Silk tweeters are known for delivering natural, detailed highs without sounding harsh or metallic. Think crisp vocals, clear instruments, and smooth cymbals that don’t pierce your ears.

The extended frequency response of 45Hz to 21kHz ensures you hear the full spectrum of your music, from deep bass notes to sparkling highs.

Designed to Fit Almost Anywhere

Space matters when upgrading car audio. The Kicker 47KSC504 keeps things simple with a smart, low-profile build. It features:

• 5-1/4 inch (130mm) woofer
• 4-1/2 inch (115mm) mounting hole diameter
• 1-3/4 inch top mount depth
• 2-inch bottom mount depth
• Minimal tweeter protrusion

That thin design makes it a solid choice for vehicles where depth is limited. Plus, grilles are included, and optional KSC5G grilles are available if you want added protection and style.

Balanced 2-Way Coaxial Design

As a 2-way speaker system, the Kicker 47KSC504 combines a dedicated woofer and tweeter into one efficient unit. The woofer handles the mids and midbass, while the tweeter takes care of the highs. Together, they create a balanced, full-range sound that feels natural and immersive.

It’s a simple upgrade that makes a noticeable difference. No complicated setups—just better clarity, better response, and better overall performance.

Built for Everyday Performance

Durability matters just as much as sound quality. The polypropylene woofer cone resists wear, and the rubber surround adds long-term reliability. These materials are chosen to handle daily driving conditions while maintaining consistent performance.

With high power handling and premium construction, the Kicker 47KSC504 is designed for drivers who want more from their music without overcomplicating their system.

Bringing Your Music to Life

The Kicker 47KSC504 transforms ordinary factory audio into something far more engaging. You get smooth highs from silk-dome tweeters, accurate mids from polypropylene woofers, and enough power handling to enjoy your music at serious volume. Compact, durable, and built for clarity, these speakers make every drive sound better—plain and simple.
