American Bass 12" Dual Voice Coil 1-Ohm 4700 Watt Subwoofer GODZILLA-12-D1

This Listing Includes:

• (1) American Bass 12" 1-Ohm GODZILLA-12-D1

The American Bass GODZILLA-12-D1 is a high-power 12-inch subwoofer engineered for extreme bass performance, durability, and long-term reliability in aggressive car audio systems. Built to handle serious power, this sub is designed for enthusiasts and competitors who demand deep, controlled low-frequency output without compromise.

At the core of the GODZILLA-12-D1 is a 3.5-inch 8-layer high-temperature flat-wire voice coil, allowing the subwoofer to manage sustained power levels while maintaining control and efficiency. Rated at 4700 watts RMS with a massive 12,000-watt maximum power handling, this subwoofer is built to withstand abuse and continue performing.

A carbon cone with foam surround and carbon fiber dust cap provides added rigidity while minimizing distortion at high excursion levels. The subwoofer’s motor structure features triple-stacked high-energy magnets, delivering strong magnetic force for authoritative low-end impact. A direct cooling T-yoke with black anodized treatment promotes efficient heat dissipation, helping prevent thermal overload during extended play.

The green-textured die-cast aluminum basket adds both structural integrity and visual impact, while dual black spiders in a mirrored layout help maintain cone stability under heavy load. Heavy-duty 4-gauge copper push terminals ensure secure power transfer for high-current applications.

Optimized for ported enclosures, the GODZILLA-12-D1 is a serious subwoofer designed for street builds and competition systems where output, control, and durability are critical.
