44L7S104 2-Pack + RXD-M4 + RWK0CU

This bundle pairs two Kicker L7S104 10-inch Solo-Baric subwoofers with a Rockville KRYPTON M4 mono amplifier and a 100% copper RWK0CU wiring kit, giving the square-cone subs both power and a clean electrical path to use it. Each sub uses an injection-molded polypropylene cone reinforced with patented corner ribs and SoloKon 360-degree back bracing, a dual 4-ohm voice coil, and a ribbed Santoprene surround, handling 600W RMS and 1200W peak per sub for a combined 1200W RMS and 2400W peak. 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, carrying more current with less voltage loss than the copper-clad wire common at this price point. These subs work best in a sealed box between 0.66 and 1.0 cubic feet per sub or vented between 1.25 and 2.25 cubic feet per sub.
