Infinity KAPPA-93IX 6x9" Coaxial (Two Pairs) + Arc Audio X2-450.4 500 Watt 4-Channel Amplifier + Wiring Kit

Complete kit includes two pairs of Infinity KAPPA-93IX 6x9" coaxial speakers, an Arc Audio X2-450.4 500 Watt 4-Channel amplifier, and a full wiring kit. The KAPPA-93IX speakers use glass-fiber woofer cones that are lighter, stiffer and offer more cone area than competing designs, producing stronger low-frequency output and improved efficiency. Instead of common W-domes, these speakers employ edge-driven textile dome tweeters for a wider, smoother high-frequency response. Their high-output 2.5 ohm architecture combined with low-impedance voice coils allows the speakers to pull maximum power from the amplifier and reproduce peak output effortlessly. Infinity subjects these speakers to extreme durability testing — freezing, baking, vibration testing, ultraviolet exposure and continuous full-power operation for days — to ensure long-term reliability.
