Product Overview

Unleash deep, impactful bass in your car audio setup with the Nakamichi FHA100 Class D Monoblock Power Amplifier. Built specifically for driving single or dual car subwoofers with extreme electrical efficiency and thermal stability, the FHA100 delivers high RMS power output without placing excessive strain on your vehicle's electrical system. Featuring an advanced Class D digital circuit layout, variable low-pass crossover filters, adjustable subsonic filter control, and a bass boost equalizer, this monoblock amplifier gives you precise acoustic control to maximize subwoofer output and eliminate distortion.

Key Features & Performance Highlights

• High-Efficiency Class D Digital Topology: Advanced Class D circuit design produces high output power with low heat generation and minimal current draw from your battery.

• Dedicated Monoblock Subwoofer Output: Specifically engineered to drive subwoofers at low impedance loads with tight, controlled low-frequency impact.

• Variable Subsonic Filter Protection: Cuts out non-audible ultra-low frequencies (below 15Hz-50Hz) to protect your subwoofer cone from over-excursion damage.

• Low-Pass Crossover & Bass Boost Control: Fine-tune your bass cutoff frequency and dial in targeted low-end punch (+0dB to +12dB @ 45Hz) to match your box tuning.

• Extruded Aluminum Heat Sink Chassis: Heavy-duty aluminum alloy housing ensures maximum thermal dissipation during continuous heavy bass playback.

• Comprehensive Circuit Protection: Integrated protection guards against thermal overload, short circuits, low/high voltage, and reverse polarity.

Frequently Asked Questions (FAQs)

1. Can I power dual subwoofers with the Nakamichi FHA100 Monoblock Amplifier?

Yes. As long as the combined final impedance of your subwoofers does not drop below 2 ohms, the FHA100 can comfortably drive dual subwoofers wired in parallel or series configurations.

2. What is the benefit of the Subsonic Filter on the FHA100?

The Subsonic Filter blocks extremely low frequencies that the human ear cannot hear but can cause your subwoofer cone to over-excursion and distort. Setting this filter protects your subwoofer and frees up amplifier power for punchier, audible bass.

3. Does this monoblock amplifier support a remote bass knob?

Yes, the Nakamichi FHA100 features a dedicated remote level control port, allowing you to mount an optional bass knob near your driver seat to adjust bass levels on the fly.

4. What components are included inside the package?

The box includes 1 x Nakamichi FHA100 Monoblock Class D Amplifier, mounting hardware, spare fuses, and user installation manual.
