Kicker 51KSC504 (5.25") & 51KSC6504 (6.5") 2-Way Thin-Mount Coaxial Speakers

New Kicker 51KSC504 5.25" and 51KSC6504 6.5" coaxial speakers — a 2-Way speaker system engineered for easy OEM-style installs. High power handling provides strong output and reliability, while silk-dome tweeters deliver smooth, detailed highs. The woofers use polypropylene cones paired with tough rubber surrounds for durable, consistent low-end performance. Thin-mount design lets these speakers fit neatly behind factory grilles for a clean, factory-fit appearance.
