KICKER KS-Series 3.5-inch Coaxial Speakers

Experience a dynamic listening experience in your vehicle with the KS-Series 3.5-inch coaxials. These compact speakers are designed to deliver concert-like energy while preserving smoothness and clarity, enabling you to enjoy a broad range of music in daily drives. The 4-ohm pair with 0.5-inch tweeters provides a balanced high end without harsh peaks, letting you hear more detail from your favorite tracks. This is the 51KSC3504 model within KS-Series, designed for reliable upgrade from factory sound.

The heart of the KS-Series is the performance-driven woofer and redesigned components. Internally dampened polypropylene cones and tough rubber surrounds help preserve midrange detail and punchy bass, even when the music hits hard. A fresh set of voice coils and crossovers rounds out the upgrade, offering a more refined overall response and reliable operation over time.

Product design and fit

• Zero (or minimal) tweeter protrusion helps ensure a clean fit in most vehicles, so you can install without extensive modifications.
• The compact 3.5-inch form factor is well suited for limited space behind dash panels, doors, or kick panels while still delivering meaningful sound.

Listening scenarios and benefits

• Ideal for daily commutes, where you want balanced mids, clear highs, and disciplined bass across genres like rock, pop, and electronic.
• For smaller, aftermarket upgrades, the KS-Series can elevate your car audio mood without requiring a full system rebuild.

Notes: This is a high-value upgrade with potential for noticeable improvement over factory sound. The combination of redesigned cones, voice coils, and crossovers aims to deliver more lifelike detail at a range of listening levels, while the minimal protrusion design helps compatibility across vehicle models.
