American Bass Godzilla Series 18" Subwoofer

The American Bass Godzilla Series 18" Subwoofer is built for serious bass enthusiasts who demand extreme low-end impact from a single driver. With a pure carbon fiber cone, a green textured diecast basket, and a 425 oz triple-stack magnet, this 18-inch woofer is engineered for high-excursion, high-power performance.

• RMS Power: 4700 W continuous power handling — enables sustained, loud bass without sag when paired with a suitable amplifier.
• Max Power: 12000 W peak power — accommodates brief transients and dynamic peaks in music without immediate clipping.
• Impedance (Ohms): D1 / D2 — dual-impedance configuration offers wiring flexibility to match your amp or enclosure setup.
• Sensitivity DB: 86.2/87.3 dB — reflects efficiency; higher numbers mean more output from the same input power in a given enclosure.
• Mounting Depth (in): 12.13 — overall depth to consider when fitting in trunk or parcel shelf installations.
• Cutout Size (in): 5.12 — the required diameter of the mounting hole for proper installation.
• Ported Box (ft³): 5.5 — recommended enclosure volume for vented operation to achieve tuned bass response.
• Magnet Size (oz): 425 — a high-mass magnet contributes to control and excursion handling for high-output bass.
• Voice Coil Size: 3.5" — a large-diameter voice coil improves heat distribution and power handling at high excursion.
• Basket Type: CAST — rigid, thermally stable frame that helps maintain alignment under heavy movement.
• Recommended Amp (Pair): Godfather 11D — pairing guidance for achieving appropriate power delivery and headroom.
• Cone Material: Pure carbon fiber — combines stiffness and lightness for better transient response and reduced cone flex.
• Basket Construction: Green textured diecast — rugged housing that supports high excursion in demanding installations.
• Spider Configuration: Double silicone spiders — added mechanical support and durability under heavy bass movement.
• Push Terminals: 4GA copper push terminals — high-current, secure connections for low-resistance wiring.
• Magnet Configuration: Triple-stack 425 oz magnet — substantial magnet structure designed to control voice coil movement at high power.

In a ported, roughly 5.5 cubic foot enclosure, this driver excels in high-performance car audio builds intended to deliver deep, authoritative bass. It pairs with the recommended Godfather 11D amplifier for the intended power delivery, supports deep mounting where space allows, and uses durable, high‑current construction to sustain heavy bass output in real-world installations.
