American Bass XMAXXX Monster Series 15" Subwoofer

The American Bass XMAXXX Monster Series 15" Subwoofer is a high‑power, cast‑basket woofer built for extreme bass in premium automotive systems. The blue powder‑coated basket and matching surround with blue stitching give this sub a classic look while delivering serious power handling, courtesy of a 4,000W RMS rating.

• RMS POWER: 4000W — Sustained power handling for high‑volume, bass-heavy music when paired with a capable amplifier and proper enclosure.
• MAX POWER: 8000W — Peak power capability to reproduce transient peaks without clipping when driven within your system’s headroom.
• IMPEDANCE (OHMS): D1/D2 — Dual voice‑coil configuration provides flexible wiring options to tailor impedance to your amp and enclosure needs.
• SENSITIVITY DB: 87.5 — Efficiency in converting electrical power to sound, influencing how much output you get per watt.
• MOUNTING DEPTH (IN): 10.8 — Depth requirement to plan fitment and enclosure design in the vehicle.
• CUTOUT SIZE (IN): 14.4 — Required hole diameter to install the sub securely in your enclosure or mounting surface.
• PORTED BOX (FT3): 3.824 — Enclosure volume specification for achieving the intended bass response in a ported design.
• MAGNET SIZE (OZ): 501 — Large magnet mass contributing to control and durability under high power handling.
• VOICE COIL SIZE: 4 — Indicates the coil diameter, a factor in heat dissipation and power handling capability.
• BASKET TYPE: CAST — Rigid, heat‑distributed frame that helps maintain cone alignment at high excursion.
• RECOMMENDED AMP (PAIR): VFL 6K — Suggested amplifier pairing for driving the pair with sufficient headroom in a high‑power install.

Benefits: This 15" Monster is designed for large, high‑power bass installations where a ported enclosure around 3.824 ft³ is used to maximize output. The dual voice coils offer wiring flexibility to match various amps, while the substantial 501 oz magnet and cast basket provide robust mechanical control for sustained, high‑level bass. With its distinctive blue finish and strong power handling, it suits premium, high‑noise environments where serious low end is the goal.
