American Bass HD Series 15" Subwoofer

The American Bass HD Series 15-inch Subwoofer is a high-output, heavy-duty woofer built for serious car audio enthusiasts who want deep, controllable bass. It handles 2000 W RMS (4000 W max) and is tuned for a 3–3.5 ft³ ported enclosure to maximize real-world bass performance in aftermarket builds.

• RMS Power: 2000W — continuous power handling for sustained bass output without clipping when paired with an appropriate amplifier.
• Max Power: 4000W — peak capability for short-term transients and dynamic music passages.
• Impedance (Ohms): D1 / D2 — dual-voice-coil configuration offering flexible wiring and amplifier compatibility.
• Sensitivity: 88 dB — efficiency rating indicating how loudly the sub will play with a given input power.
• Mounting Depth (in): 9.4 — depth required for installation; informs fitment in trunk or cargo areas with limited space.
• Cutout Size (in): 14.4 — hole diameter needed for proper mounting and sealing in the enclosure or mounting surface.
• Ported Box (ft³): 3 – 3.50 — recommended enclosure volume to achieve tuned, vented bass performance.
• Magnet Size (oz): 350 — large magnet for improved control of cone motion and reduced thermal compression during heavy bass.
• Voice Coil Size: 3 in — larger coil aids heat dissipation and supports higher excursion under demanding passages.
• Basket Type: Cast — rigid frame to maintain alignment and minimize distortion under high power.
• Recommended Amp (Pair): VFL 4K — pairing with this amplifier in a dual-sub setup is suggested for balanced, high-output performance.

In a real car audio build, this sub is chosen for high-power, single- or dual-sub installations that demand deep, impactful bass within a sizable ported enclosure. The combination of a 350 oz magnet, 3" voice coil, and cast basket provides robust control and reliability, while the 9.4" mounting depth and 14.4" cutout guide correct fitment for larger openings. The 3–3.5 ft³ enclosure recommendation helps tune bass response to your vehicle’s acoustics when paired with a high-powered amplifier such as the VFL 4K.
