Cerwin-Vega H746 4"x6" 2-Way Coaxial Car Speakers

The Cerwin-Vega H746 is a pair of 4" x 6" HED Series coaxial car speakers designed to replace factory speakers in compatible vehicle locations. Its compact format is suited to many door, dash, and rear-deck applications that use a 4" x 6" opening. The two-way design combines woofer and tweeter elements in each speaker for a straightforward full-range upgrade.

These speakers are intended for drivers who want clearer everyday playback from a factory radio or a modest aftermarket system. With 40 watts RMS handling per speaker and a 4-ohm load, they can be matched with compatible head-unit power or an appropriately rated amplifier. Their 86 dB sensitivity specification provides a useful reference when comparing output requirements with other speakers.

The H746 uses a polypropylene cone with a treated-foam surround to handle midrange and lower-frequency duties. A 1-inch balanced-dome PEI tweeter is used for high-frequency reproduction. Together, the coaxial layout keeps the installation compact while covering the listed 60 Hz to 20 kHz frequency-response range.

Its construction includes a stamped-steel basket and ferrite magnet motor structure. The speaker also uses a 1-inch voice coil and an internal crossover, so a separate external passive crossover is not required for its integrated tweeter. These details make the H746 a practical replacement-speaker design rather than a component-speaker system.

The H746 can be used as a direct-size replacement where vehicle fitment, mounting depth, and cutout dimensions are confirmed before installation. It is sold as a pair, providing left and right speakers for one 4" x 6" location pair. For a more extensive audio upgrade, it can be paired with compatible wiring, mounting hardware, sound treatment, and amplification selected for the vehicle.

Key Features

• 4" x 6" Size: Fits applications designed for this compact speaker format.
• Two-Way Coaxial Design: Integrates woofer and tweeter in each speaker.
• 40W RMS Per Speaker: Supports continuous power handling for compatible systems.
• Polypropylene Cone: Provides a durable cone material for everyday playback.
• PEI Balanced-Dome Tweeter: Handles high-frequency detail within the coaxial assembly.
• Internal Crossover: Directs frequencies between the integrated drivers.

Design & Installation

The H746 uses a polypropylene cone, treated-foam surround, Mylar diaphragm material, stamped-steel basket, and ferrite ceramic magnet. Its integrated 1-inch PEI balanced-dome tweeter and internal crossover keep the speaker assembly self-contained. The construction is designed for standard in-vehicle speaker replacement use.

Confirm that the vehicle accepts 4" x 6" speakers and verify the 5.6" x 3.5" mounting cutout and 1.8" mounting-depth requirements before purchase. Connect each speaker to a compatible 4-ohm channel and use secure mounting hardware and correct-polarity wiring. Factory-grille clearance, adapter brackets, wiring harnesses, and installation accessories should be checked for the specific vehicle because they are not confirmed as included.
