The Hifonics HFX12D4 is a 12-inch dual 4-ohm subwoofer engineered for cars, trucks, SUVs, and powersports builds, delivering deep, controlled bass with 800 watts peak and 400 watts RMS. Its heavy-gauge, powder-coated steel basket with back venting improves heat dissipation and reliability, while a vented aluminum former and 2-inch voice coil help reduce heat-related distortion. A pressure-treated foam surround and specialized poly-cotton spider keep piston motion linear for clean, punchy low end, and the vented high-energy motor with heavy-duty magnets enhances SPL for an immersive listening experience. Designed for quick installs with spade-style terminals, this round, universal-fit subwoofer is ideal for small sealed or medium to large vented enclosures, and features a 5.61-inch mounting depth, 10.94-inch cutout diameter, 12.25-inch outside diameter, and 86 dB sensitivity, offering durable construction and powerful performance in a compact package.
