The Sky High Car Audio FMX Series 12" Subwoofer is a no-nonsense heavy-duty woofer built for serious power, long demos, and competition-leaning daily systems. Part of the FMX line rated at up to 3500W RMS, the 12 inch version gives you that “big boy” motor and suspension design in the most popular subwoofer size for trunks, SUVs, and blow-through setups.

FMX stands for “Forged to Perform. Built to Endure.” — this line was engineered from real-world abuse, not just spec sheet flex. The FMX 12 uses an overbuilt motor, high-temperature coil, and rugged suspension that can handle high clamp power when paired with proper electrical and a well-designed enclosure. This is the 12 inch you pick when you want a true high-power subwoofer that can live in a daily vehicle.

Available in dual 1 ohm (D1) and dual 2 ohm (D2) voice coil options, the FMX Series 12" makes it easy to design low-impedance systems, strap big monoblocks, and scale up to multi-sub setups without fighting odd wiring combinations.
