Experience deep, chest-thumping low ends with the MX12D4s 600 Watts RMS (1200W Max) power handling. Engineered for high-performance car audio systems, this 12-inch subwoofer delivers consistent, powerful bass that maintains clarity even at high volume levels. It is the perfect upgrade for bass enthusiasts. Built to survive long, intense listening sessions, it features a 2.5" 4-layer high-temperature copper voice coil wound on a black aluminum former. An Advanced Air Flow Cooling Design effectively dissipates heat to prevent thermal breakdown. The Dual 4-Ohm (D4) configuration provides ultimate flexibility for your system setup. Wire it in parallel for a 2-Ohm load to pull maximum power from your monoblock amplifier, or in series for an 8-Ohm configuration, making it compatible with a wide range of car audio amplifiers. The MX12D4 utilizes a Competition Grade Pressed Paper Cone and a high-roll surround for maximum excursion and durability. This combination allows for a high sensitivity of 87.6dB, ensuring that every watt of power is efficiently converted into crisp, distortion-free sound. Equipped with a massive 99 Oz High Flux Ferrite Motor, this subwoofer provides the magnetic strength needed for precise cone control and a low resonant frequency (40.3Hz). Whether it's in a sealed or ported box, the MX12D4 is designed to deliver the "low-end growl" that standard factory speakers can't match.
