Crunch CS4CX 4-Inch Coaxial Car Speakers

The Crunch CS4CX is a 4-inch, two-way coaxial car-speaker set designed for compact factory speaker locations and custom vehicle audio installations. It combines a full-range woofer and a centrally mounted tweeter in each speaker to provide a straightforward upgrade path where space is limited. With a 4-ohm impedance and universal vehicle compatibility listing, it is intended for use in a wide range of car audio systems.

This model is rated for 100 watts RMS power handling and 200 watts peak power handling. Its stated 55 Hz to 19 kHz frequency response is designed to cover bass, midrange, and high-frequency duties within a compact speaker format. The 88 dB sensitivity rating provides a useful reference when matching the speakers with a compatible head unit or external amplifier.

A 1-inch Neo-Mylar soft-dome tweeter handles the upper-frequency range, while the silver alpha-cellulose poly cone is intended to reproduce midrange and bass information. The coaxial arrangement keeps the installation compact by placing the tweeter directly within the speaker assembly. A passive Butterworth crossover is integrated to route frequencies between the woofer and tweeter.

The CS4CX uses a UV-resistant, moisture-resistant rubber surround and high-temperature adhesive at the cone connection. These materials support use in vehicle door, dash, or rear-panel locations that may experience vibration and changing temperatures. An over-coil cooling system moves air over the voice coil through the spider to support heat management during operation.

For a balanced system upgrade, the CS4CX can be used where a 4-inch speaker location has sufficient mounting clearance. Its compact format suits systems that need improved high-frequency detail and midrange presence without changing to a larger speaker size. Confirm the vehicle's opening, mounting depth, and available space before installation.

Key Features

• 4-Inch Two-Way Coaxial Design: Combines woofer and tweeter functions in a compact speaker assembly.
• 100W RMS Power Handling: Supports matching with compatible car stereo or amplifier power.
• 1-Inch Neo-Mylar Tweeter: Provides dedicated high-frequency reproduction in each speaker.
• Silver Alpha-Cellulose Cone: Supplies lightweight cone construction for midrange and bass reproduction.
• Rubber Surround: Uses UV- and moisture-resistant material around the cone edge.
• Stamped Steel Basket: Provides a rigid mounting structure designed to limit frame resonance.

Design & Installation

The CS4CX uses an anti-resonant stamped steel basket, ferrite magnet motor, pure copper voice coil, and lightweight Kapton voice-coil former. Its epoxy-infused natural-fiber spider provides flexibility and structural support, while a textured ABS gasket helps create a seal against the mounting surface. The black speaker design is intended to install behind an OEM panel, and protective grilles are not included.

Verify a 3.69-inch cutout, 5.39-inch outside diameter, and 3.0-inch mounting-depth requirement before purchasing. The speakers use spade terminals and may also be soldered directly for connection. Match the installation to a compatible 4-ohm audio source, observe speaker polarity, and use the stated RMS rating rather than peak power when selecting amplification.
