More about the product
The Kicker 51KSC404 4-Inch Coaxial Speakers are built for clear, detailed sound in a compact design. They are ideal for upgrading factory audio without taking up extra space. Each speaker uses a polypropylene woofer cone for smooth midrange performance and durability. The cone is paired with a tough rubber surround that helps maintain accuracy and reduces distortion at higher volumes.
The 51KSC404 features a 2-way design with a silk dome tweeter for crisp, natural highs. This combination delivers balanced audio across different music styles, from vocals to instruments. With less than a 2-inch mounting depth and zero tweeter protrusion, the KSC404 is a perfect fit in almost every vehicle on the road today. Installation is simple, even in tight spaces, and grilles are included for a clean finish.
These speakers work best with 15 to 75 watts of recommended power, making them suitable for factory or aftermarket head units. The sensitivity rating of 88 dB ensures efficient performance without needing excessive amplification. Their 4-ohm impedance makes them compatible with most car audio systems.
While the Kicker 51KSC404 delivers excellent clarity and improved detail compared to stock speakers, it is not designed for heavy bass. Pairing with a subwoofer is recommended for those seeking full-range sound. The slim profile and shallow mounting depth make these speakers a practical choice for vehicles with limited space behind panels.
Overall, the Kicker 51KSC404 offers a reliable upgrade for anyone wanting better audio quality without complex installation or large components. It combines quality materials, smart design, and easy fitment for a noticeable improvement in everyday listening.
