44CVX124 2-Pack + RXD-M4 + RWK0CU

This bundle pairs two Kicker CompVX 50CVX124 12-inch subwoofers with a Rockville KRYPTON M4 mono amplifier and a 100% copper RWK0CU wiring kit, giving a 12-inch build both the low end and the power behind it. Each sub uses a cast-aluminum basket with motor-cooling venting, a ribbed Santoprene surround around a thick polypropylene cone, and a dual 4-ohm voice coil, handling 750W RMS and 1500W peak per sub for a combined 1500W RMS and 3000W peak across the pair. The KRYPTON M4 supplies 1500W Dyno-certified RMS at 1 ohm, a digital voltage display accurate to 0.15V, and a bass remote with a clipping indicator that lets you set gain right at the edge of distortion without crossing it. A 150A external fuse and an adjustable 12dB/octave crossover with a 15-55Hz subsonic filter round out the amp's protection and tuning. The RWK0CU kit steps up to 0-gauge, 100% virgin copper power and ground cable to carry the higher current this amp needs with minimal voltage loss. Spring-loaded terminals on the subs accept up to 10-gauge wire directly, and they perform best in a sealed box from 1.0 to 4.6 cubic feet or vented from 1.75 to 2.25 cubic feet per sub, leaving the enclosure choice open.
