HFV Audio FX 3000.1 compact car audio subwoofer amplifier 3K, 3000 watts
Compact. Clean Sound. Big Power.
At HFV Audio, our mission is simple: deliver high-end sound quality, real-world power, and rugged build quality—without inflated pricing. The FX-3000.1 monoblock amplifier delivers serious output in a compact, high-performance chassis designed for demanding systems and tight installations.
Built for subwoofer dominance, the FX-3000.1 delivers a true 3000 watts at 1 ohm, producing deep, hard-hitting bass with excellent control and low distortion. Although it uses a full-bridge Class D design, it is specifically engineered to hit the lows with the authority of a half-bridge amplifier, giving you exceptional low-end impact without sacrificing efficiency.
HFV amplifiers are designed to reproduce true low-frequency energy, starting as low as 10 Hz, ensuring powerful subsonic bass that many amplifiers struggle to maintain. The damping of the FX-3000.1 offers excellent cone control for a full-bridge amplifier, outperforming many competing designs and delivering tighter, more accurate bass response.
Despite its compact size, the FX-3000.1 is built to handle serious output. A heavy-duty aluminum heatsink paired with (4) integrated cooling fans actively removes heat from critical components, allowing the amplifier to stay cool under heavy load for consistent performance and long-term reliability.
Included with the amplifier is a remote bass knob with an integrated digital voltmeter, giving you real-time system voltage monitoring right from the driver’s seat. The remote also features power and clip LED indicators, so you can instantly see amplifier status and avoid overdriving your system. A built-in calibration adjustment allows you to fine-tune the voltmeter for accurate voltage readings based on your vehicle’s electrical system.
