NVX 12" N-Series Car Subwoofer NSW124v3 — 12" Dual 4Ω, 500W RMS Deep Controlled Bass

The NVX NSW124v3 is a 12-inch dual 4-ohm car subwoofer delivering up to 1000W peak (500W RMS) of deep, controlled bass for robust in-car audio.

The NSW124 Version 3 from NVX is engineered to bring bold low-frequency impact without sacrificing reliability. Built with a reinforced pressed paper cone, high-roll foam surround, and a stout double-stacked ferrite magnet, this subwoofer balances punch, control, and thermal stability. Whether you’re upgrading a factory system or building a custom enclosure, the NSW124v3 is designed to perform in a range of sealed or ported setups.

How does the NSW124v3 deliver strong, distortion-free bass?

The speaker combines a rigid 12" cone and a high-roll foam surround to maintain cone integrity at high excursion. A 2.0" copper voice coil and progressive single-layer spider give precise control over movement, reducing unwanted distortion at louder volumes.

• 12-inch enhanced pressed paper cone for solid low-end response
• High-roll foam surround to allow larger cone excursion
• 2.0" high-temperature copper voice coil for consistent power handling
• Progressive roll spider for improved linear motion and control

What cooling and durability features keep it reliable under heavy use?

Thermal management and mechanical protection are central to this design. The optimized high-velocity pole vent channels heat away from the voice coil, while the 112 oz. double-stacked ferrite magnet with a protective rubber boot shields the motor structure from impact and environmental wear.

• High-velocity pole vent to reduce voice-coil temperature rise
• Double-stacked 112 oz. ferrite magnet for stable motor force
• Protective rubber boot to guard the magnet assembly
• Robust build materials for long-term durability

Which power ratings and impedance options suit my amplifier setup?

The NSW124v3 is rated for 500W RMS and 1000W peak, making it compatible with a wide range of aftermarket amplifiers. Its dual 4-ohm voice coils provide wiring flexibility so you can present the amplifier with the desired final impedance.

• 500W RMS continuous handling for reliable daily performance
• 1000W peak for transient headroom during dynamic passages
• Dual 4-ohm coils allow series, parallel, or single-coil wiring options
• Works well in both sealed and ported enclosures when matched properly

How will this subwoofer fit into my car audio project?

Designed as a versatile 12" option, the NSW124v3 can be used in custom boxes, sealed enclosures for tight, accurate bass, or ported enclosures for extra output. Its physical footprint and mounting depth are compatible with many factory and aftermarket locations, but measuring available space is recommended before purchase.

• Sized for common 12" enclosures and custom builds
• Sealed boxes emphasize accuracy; ported boxes increase output
• Dual terminals simplify wiring to match amplifier impedance
• Durable cone and surround for repeated heavy use

Who is this for? The NVX NSW124v3 is aimed at drivers and installers who want a dependable, high-output subwoofer that balances loudness with accuracy. It suits enthusiasts upgrading stock systems, weekend show cars needing solid low end, and installers building mid- to high-power amplifer-driven enclosures. If you need a durable 12" woofer capable of handling sustained 500W RMS power with flexible wiring options, the NSW124v3 is a practical choice.
