CS-Series Coaxial and 3-Way Speakers have been designed to fit nearly every make and model of vehicle, making for a manageable, drop-in audio solution that delivers acclaimed KICKER performance and durability at the most affordable price.
CS Coaxial and 3-Ways are available in eight sizes and have been optimized to fit almost any cutout, providing a substantial upgrade to factory speakers and the perfect complement to a KICKER Yellow audio system. They feature drastically reduced mounting depths on woofer baskets and zero tweeter protrusion* for absolutely no physical interference with factory grilles, providing drivers that fit factory locations in numerous vehicles.
The CS-Series delivers remarkable performance and ultra-clean bass, utilizing a heavy-duty motor/magnet structure featuring EVC (Extended Voice Coil) technology not found in stock speakers. They use polypropylene cones with tough, ribbed, UV-treated surrounds for precise linear excursion and reliability. Lightweight, 13mm PEI-dome tweeters offer superb clarity and volume, helping each CS-Series Coaxial pair provide substantially high power handling and superior sound over factory drivers.
A rugged 6x9-inch 3-way remains a popular model, which includes an integrated 2-inch midrange driver for extra audio output and range.
