Crunch CS525CX 5.25" 2-Way Coaxial Car Speakers

The Crunch CS525CX is a 5.25-inch, 2-way coaxial speaker designed for replacing worn factory speakers or building a straightforward car-audio upgrade. Its compact format combines a midrange/midbass driver and tweeter in one assembly, helping simplify installation where a 5.25-inch speaker location is available. It is intended for universal vehicle applications, subject to confirming mounting dimensions and clearance in the vehicle.

This speaker is suited to listeners who want fuller everyday sound from a compact coaxial design without adding separate tweeters and external crossover hardware. The silver alpha-cellulose cone is engineered to reproduce musical midrange and bass tones while remaining lightweight. A 60 Hz to 20 kHz published frequency response supports broad-range playback for front or rear speaker locations.

For high-frequency detail, the CS525CX uses a 1-inch neo-Mylar soft-dome tweeter. The coaxial arrangement places the tweeter with the main driver for a consolidated installation, while the passive crossover system manages the transition between driver sections. This approach makes it practical for factory-speaker replacement projects and basic aftermarket systems.

Crunch builds the CS525CX around a stamped-steel basket, ferrite motor, pure-copper voice coil, and Kapton former. The rubber surround is UV- and moisture-resistant, while high-temperature adhesive is used at the cone and surround connection. These construction details are intended to support regular automotive use in changing temperatures and vibration conditions.

With a 4-ohm impedance and 125-watt RMS power-handling specification, the CS525CX can be used with a compatible factory or aftermarket audio system when power is matched appropriately. Its 4.48-inch mounting cutout and 2.0-inch mounting depth should be checked against the vehicle before purchase. Protective grilles are provided for installations where the speakers are exposed rather than mounted behind factory panels.

Key Features

• 5.25-Inch Coaxial Design: Combines the woofer and tweeter in one speaker assembly.
• Neo-Mylar Soft-Dome Tweeter: Provides high-frequency reproduction in a compact integrated design.
• Alpha-Cellulose Cone: Supports lightweight midrange and midbass performance.
• Rubber Surround: Resists moisture and UV exposure while supporting cone movement.
• Stamped-Steel Basket: Provides a rigid mounting structure with reduced resonance.
• Spade Terminals: Allow compatible spade connectors or direct soldering.

Design & Installation

The CS525CX uses a black anti-resonant stamped-steel basket, ferrite magnet motor, textured ABS gasket, silver alpha-cellulose cone, and moisture-resistant rubber surround. Its pure-copper voice coil is paired with a lightweight Kapton former, and the spider uses epoxy-infused natural fiber. An over-coil cooling design exchanges air through the spider around the voice-coil area.

Confirm that the vehicle accepts a 5.25-inch speaker and verify the 4.48-inch cutout, 6.26-inch outside diameter, and 2.0-inch mounting depth before installation. Connect using properly sized spade terminals or soldered speaker leads, observing polarity from the head unit or amplifier. Use the supplied grilles when the speakers are not protected by factory door or rear-deck panels.
