Nakamichi NBS210A Compact Active Subwoofer Box with Remote Control

Transform your vehicle's audio with compact, remotely controlled bass—perfect for underseat installation in smaller vehicles.

Product Overview

The Nakamichi NBS210A is an ultra-compact active subwoofer box featuring an integrated 100W amplifier and convenient remote bass control. Delivering 1000W peak power in a space-efficient 300 x 275 x 318mm enclosure weighing just 7.2kg, this all-in-one solution fits easily under seats, behind seats, or in tight boot spaces where traditional subwoofers won't. The system features professional-grade audio performance with less than 0.1% THD distortion, greater than 90dB signal-to-noise ratio, and 40-160Hz frequency response with fixed 20Hz subsonic filtering for clean, controlled bass. The included wired remote control allows real-time bass level adjustment from the driver's seat without reaching for the subwoofer—perfect for switching between music genres, podcasts, or phone calls during Australian city commuting. With adjustable input sensitivity (0.5-280mV) and simple power connections, the NBS210A integrates seamlessly with both factory and aftermarket audio systems without complex amplifier installations.

Features & Benefits

Ultra-Compact Underseat Design: At just 300 x 275 x 318mm and 7.2kg, this is one of the most compact active subwoofers available—fits under most vehicle front seats or in tight boot corners without consuming valuable cargo space, ideal for hatchbacks, sedans, and compact SUVs where space is premium.

Remote Bass Control Convenience: Included wired remote allows instant bass level adjustment from the driver's seat while driving—turn bass down for podcasts and phone calls, increase for music during highway cruising, all without reaching for the subwoofer or stopping the vehicle.

Built-In Amplifier Simplicity: Integrated amplifier eliminates the need for separate amplifier purchase, complex wiring, and additional mounting space—simply connect power, ground, remote turn-on, and audio signal for instant bass enhancement, perfect for factory system upgrades or simple aftermarket installations.

Exceptional Audio Quality: Less than 0.1% THD and greater than 90dB SNR deliver clean, accurate bass reproduction without distortion or background noise—ensuring your music, podcasts, and hands-free calls sound clear and professional even at higher volume levels during daily commuting.

Wide Input Sensitivity Range: Adjustable 0.5-280mV input sensitivity accommodates both weak factory headunit outputs and powerful aftermarket source signals—allows proper gain matching for balanced bass response whether you're upgrading from factory audio or integrating with existing aftermarket components.

Subsonic Filter Protection: Fixed 20Hz subsonic filter prevents wasted amplifier power on inaudible ultra-low frequencies and protects the subwoofer from overexcursion—ensures efficient power usage and long-term reliability especially important for Australian outback touring where component replacement isn't convenient.

Low Electrical Draw: 100W continuous power with 20A fuse protection means modest electrical system requirements suitable for smaller vehicles, older vehicles, or those with limited alternator capacity—won't drain batteries or stress charging systems even when running auxiliary accessories like lighting or fridges.

Factory System Integration: Adjustable input sensitivity accepts signals from factory headunit speaker outputs (with inline adapters) or aftermarket preamp outputs—makes upgrading factory audio simple without replacing entire systems, preserving warranty coverage on newer vehicles.

Frequently Asked Questions

Will this fit under my vehicle's front seats?

The NBS210A measures 300 x 275 x 318mm—among the most compact active subwoofers available. It fits under most vehicle front seats with 320mm+ clearance. Measure your underseat space (height, width, depth) and verify against these dimensions. Alternatively, install behind rear seats or in boot corners.

How does the remote bass control work?

The included wired remote control installs within driver's reach (typically dashboard or centre console) with supplied cable connecting to the subwoofer. Turn the knob to increase or decrease bass output in real-time—perfect for adjusting bass levels between music, podcasts, navigation instructions, and phone calls without stopping.

Do I need a separate amplifier with this subwoofer?

No, the NBS210A is an active (powered) subwoofer with built-in 100W amplifier. Connect directly to your headunit's subwoofer pre-output or use a line output converter with factory systems. No external amplifier purchase or installation required—significant cost and installation time savings.

Can I connect this to my factory stereo system?

Yes, but most factory stereos lack dedicated subwoofer outputs. You'll need a line output converter (LOC) to tap factory speaker wires and convert to line-level signal the active subwoofer requires. Adjust the subwoofer's input sensitivity to match your factory system's output level for optimal performance.

How much power does this draw from my battery?

At 100W continuous output, the subwoofer draws approximately 10-12 amps during normal use from your 12V system. The included 20A fuse protects against overload. Use minimum 10-gauge power cable with the supplied 20A fuse positioned within 450mm of battery connection. Suitable for most vehicles without electrical upgrades.
