Hifonics HCC46CX 4 x 6-Inch 2-Way Coaxial Car Speakers

The Hifonics HCC46CX is a pair of 4 x 6-inch, 2-way coaxial car speakers designed as a factory-speaker replacement or compact audio-system upgrade. They combine a woofer and tweeter in each speaker assembly, helping simplify installation where a 4 x 6-inch speaker location is available. With 4-ohm impedance and 40 watts RMS power handling per speaker, they are suited to compatible factory radios or appropriately matched aftermarket amplification.

A 1-inch aluminum dome tweeter handles upper-frequency detail, while the lightweight blue woven fiber cone is designed for responsive midrange reproduction. The stated 80Hz-20kHz frequency response covers core mid-bass, vocal, and high-frequency content. Butyl rubber surrounds support cone movement while providing a durable connection between the cone and frame.

The HCC46CX uses a passive Butterworth crossover with a 6kHz, 12dB slope to divide frequencies between the woofer and tweeter. This integrated crossover design keeps the speaker package self-contained without requiring a separate external crossover module. Its 88dB sensitivity rating provides a useful reference point when comparing it with other replacement speakers.

Hifonics builds the speaker around an anti-resonant stamped steel basket and a ferrite magnet motor. A pure copper voice coil on a Kapton former is paired with an overcoil cooling system that moves air over the voice coil through the spider. The epoxy-infused natural fiber spider supports the moving assembly while contributing to the speaker's structural design.

These speakers are intended for vehicles with suitable 4 x 6-inch mounting locations, a 5.5 x 3.84-inch cutout, and 3.0 inches of mounting depth. Spade terminals and direct-solder connection options allow installers to choose an appropriate wiring method. They can be used as a straightforward replacement pair or as part of a broader system upgrade with matched amplification and source equipment.

Key Features

• 4 x 6-Inch Coaxial Design: Combines woofer and tweeter elements in each speaker for a compact replacement format.
• 1-Inch Aluminum Dome Tweeter: Provides dedicated high-frequency reproduction within the coaxial assembly.
• Blue Woven Fiber Cone: Uses a lightweight cone material designed for responsive midrange performance.
• Butyl Rubber Surround: Supports cone movement and provides durable cone-to-frame coupling.
• Passive Butterworth Crossover: Uses a 6kHz, 12dB crossover slope to divide frequencies between drivers.
• Overcoil Cooling System: Promotes airflow over the voice coil through the speaker spider.

Design & Installation

The HCC46CX uses an anti-resonant stamped steel basket, ferrite magnet motor, pure copper voice coil, and lightweight Kapton former. Its epoxy-infused natural fiber spider supports the moving components, while the butyl rubber surround and woven fiber cone complete the woofer assembly. The speakers have a black and blue finish and do not include grilles, as they are generally installed behind an existing vehicle panel or dash location.

Confirm the vehicle's available opening, mounting cutout, and clearance before purchase: this model requires a 5.5 x 3.84-inch cutout and 3.0 inches of mounting depth. Connect using compatible spade terminals or direct soldering, observing correct speaker polarity. For amplified installations, select an amplifier and gain setting appropriate for the speakers' 40-watt RMS, 4-ohm rating.
