Take total control over your car audio system’s frequency management with the Hifonics HFXR 2/3-Channel Active Crossover, a versatile processor built for serious setups. Whether you’re driving a car, truck, or building a custom vehicle stereo system, this unit lets you separate and shape audio with precision across front, rear, and subwoofer channels. With the ability to switch between 2-channel or 4-channel input operation, the HFXR adapts to mono sub setups or full stereo configurations for maximum flexibility.At its heart is an 8.5-volt line driver preamp output that delivers a strong, clean signal to your amplifiers, reducing noise and maintaining clarity even at higher volumes. A dedicated pre-amp direct sub in and sub-out path means your bass channel gets a signal optimized separately for low-end control. You also get a remote bass level knob, so you can tweak the bass output from the driver’s seat, and a 45 Hz bass boost via a quasi-parametric EQ for deep tunable lows.Front and rear high-pass filters use 2nd-order Butterworth topology, letting you set the cut-off frequencies for front and rear channels so your speakers only see the frequencies they are designed for. A 180-degree phase-shift switch helps align your subwoofer with the rest of your system to ensure coherent bass. Level adjustments for front, rear and sub channels provide granular control over each output. RCA pre-amp outputs allow cascading to additional components if your build evolves.With a full frequency response from approximately 10 Hz to 30 kHz, channel separation higher than 60 dB, signal-to-noise ratio better than 95 dB, and total harmonic distortion below 0.01%, it is engineered for clean signal processing. The Hifonics HFXR 2/3-Channel Active Crossover gives your audio system the precision it needs, from subtle tweaks to full system equalization, and ensures your front, rear and sub outputs are working in harmony for high-quality sound.
