The JL Audio C2-650x is a 6.5-inch coaxial speaker system that includes mineral-filled polypropylene woofers and 0.75-inch silk dome tweeters. The system is sold as a pair and includes black grille trays with satin silver accents and black steel mesh grilles with an electroformed JL Audio logo.

Drivers feature long excursion woofer designs with stamped steel frames and multiple mounting patterns for straightforward installation in many vehicles that accept 6.5-inch speakers. The coaxial silk dome tweeters are compact to minimize protrusion and fit behind most factory grilles. Recommended amplifier power range and electrical specs support use with factory head units or aftermarket amplification.
