DS18 ZXI12.4D 12" High Excursion Car Subwoofer 2000W Watts Dvc 4-Ohm 4 Magnets

The DS18 ZXI12.4D is a high-excursion 12″ car subwoofer engineered for deep, powerful bass. It features a dual 4‑ohm (4 + 4 Ω) voice coil design with stacked ferrite magnets to achieve up to 2000 W peak power handling. With a massive 3″ voice coil and 32 mm Xmax, this driver can move large volumes of air while maintaining control, making it ideal for SPL (sound pressure level) and high-output systems.

Key Benefits

• Massive Power Handling: Rated for 1000 W RMS and up to 2000 W peak, giving plenty of headroom for high-power amplifiers. 
• High Excursion Design: 32 mm one-way Xmax for dynamic, low-distortion bass. 
• Stacked Quad Magnets: Four ferrite magnets (224 oz total) for strong magnetic force and long excursion. 
• Large Voice Coil: 3″ black-aluminum former increases thermal capacity and durability. 
• Durable Cone & Suspension: Non-pressed paper cone with foam surround offers reliability under stress. 
• Versatile Wiring Options: Dual 4‑ohm coils let you wire for 2Ω or 1Ω, depending on amplifier configuration. 
• Deep Bass Performance: Low resonance frequency (around 31 Hz) allows very deep output.

Installation & Compatibility

Enclosure Recommendations:

Sealed: ~21.2 L (0.75 ft³) gives a tight, punchy response. 

Ported: ~39.6 L (1.4 ft³), tuned to 32 Hz for deeper extension. 

Use a 90 Hz low-pass filter to protect the sub and optimize low-frequency performance. 

The 7.55″ mounting depth makes it usable in a variety of custom enclosures, but check your box to ensure adequate clearance.

With its dual 4‑Ω coils, you can wire for 2 Ω (parallel) or 1 Ω (series/parallel) depending on your amplifier and goals.
