American Bass King Series 18" Subwoofer

American Bass KING Series 18" Subwoofer is a high‑power bass driver built for extreme car‑audio fans, delivering deep, controlled low end with a 613 oz triple‑stacked magnet, die‑cast basket, and a carbon‑cone design with foam surround.

• RMS Power: 6500W — represents continuous power handling; in practice this means the driver can sustain high average input when paired with an appropriately sized amplifier without thermal collapse.
• Max Power: 15000W — peak power capacity for brief transients; useful for short bass bursts while maintaining control.
• Impedance (OHMS): D1/D2 — dual voice‑coil configuration offering wiring versatility and compatibility with multiple amp loads in high‑power systems.
• Sensitivity DB: 86.3 — efficiency rating; in a vehicle, this influences how much amplifier power is needed to reach target SPL levels.
• Mounting Depth (IN): 13.189 — required depth inside the mounting cavity; affects fitment in deeper enclosures and trunk spaces.
• Cutout Size (IN): 16.85 — diameter of the hole needed to install the subwoofer into a panel or enclosure.
• Ported Box (FT³): 6.5 — recommended enclosure volume for a ported configuration to achieve specific bass response characteristics.
• Magnet Size (OZ): 613 — large magnet provides strong motor force for better control at high excursion and high power.
• Voice Coil Size: 4.5 — high‑temperature flat wire coil designed to withstand substantial power and heat during extended play.
• Basket Type: Cast — rigid, heavy‑duty frame that helps minimize vibration and distortion under demanding workloads.
• Recommended Amp (PAIR): Godfather 11D — suggested amplification pairing to achieve intended performance in a multi‑sub setup.
• Direct Cooling System — thermal management feature that aids sustained high‑power operation by improving heat dissipation.
• Carbon Cone Foam Surround — contributes to cone stiffness and excursion control for accurate low‑end response.
• Carbon Fiber Dust Cap — adds rigidity to the center of the cone for reduced total movement distortion.
• 4GA Copper Push Terminals — high‑current connections designed to minimize resistance and maintain solid electrical transfer.
• Black Anodized T‑Yoke — durable, stiff mounting point that supports the motor structure and alignment.
• Double Black Spider — enhanced suspension for linear travel and control under heavy bass.

Benefits: This 18" KING sub is built for high‑output, competition‑style installations where extreme bass authority is required. It fits a 16.85" cutout and 13.189" mounting depth, typically in large ported enclosures around 6.5 ft³ to maximize low‑end extension and efficiency. The combination of the massive 613 oz magnet, cast basket, dual voice coils, and robust cooling keeps the driver under control during long, intense bass sessions, while the recommended Godfather 11D amplifier pairing helps unlock its 6500W RMS rating with reliable headroom. Ideal for users seeking serious SPL with durable construction and precise low‑frequency control in a capable, high‑power system.
