Kenwood KFC-4675C 4" x 6" 2-Way Car Speakers

The Kenwood KFC-4675C is a pair of 4 x 6-inch, 2-way car speakers designed to replace worn or limited factory speakers in compatible vehicle locations. Its compact oval format suits vehicles that use 4 x 6-inch speaker openings. The speakers use a 4-ohm nominal impedance for use with compatible car audio systems.

This model is intended for drivers seeking a straightforward factory-speaker replacement without changing to a larger speaker size. A 20-watt RMS rated input and 90 dB/W at 1 m sensitivity make it appropriate for modest-power factory radios or carefully matched amplification. It can also be used as part of a broader speaker refresh when matching vehicle fitment is confirmed.

The 2-way design combines an injection polypropylene cone woofer with a 1-inch PEI balanced-dome high-frequency driver. The woofer handles the main range of music playback while the separate dome driver extends high-frequency reproduction. Kenwood specifies a 50 Hz to 25 kHz frequency response.

A steel basket and ferrite magnet provide the speaker's core structure, while the black finish maintains a discreet installed appearance. The 4 x 6-inch woofer format is built around a compact footprint for factory-style mounting locations. Its 1-5/8-inch mounting depth should be checked against available door, dash, or rear-deck clearance before installation.

The KFC-4675C is sold as a pair, making it suitable for replacing two factory speaker positions at once. It is a full-range speaker solution rather than a subwoofer, so low-bass output will depend on the vehicle, installation location, and the rest of the audio system. For an accurate fit, compare the vehicle's opening, mounting depth, mounting pattern, and wiring connection with the speaker dimensions before purchase.

Key Features

• 4 x 6-Inch Format: Fits compatible oval factory speaker locations.
• 2-Way Design: Separates woofer and high-frequency driver duties.
• Injection PP Woofer: Uses a polypropylene cone diaphragm.
• 1-Inch PEI Balanced Dome: Handles high-frequency playback.
• 4-Ohm Impedance: Matches many conventional car audio systems.
• 90 dB Sensitivity: Supports output from modest-power sources.

Design & Installation

The KFC-4675C uses an injection polypropylene woofer cone, a 1-inch PEI balanced-dome driver, a black steel basket, and a ferrite magnet. The speaker measures 6-1/4 inches wide by 4 inches high and 3-1/16 inches deep without a grille. Kenwood specifies a 1-5/8-inch mounting depth.

Confirm that the vehicle accepts a 4 x 6-inch speaker and has sufficient mounting depth before installation. The package is listed with two speakers, speaker-wire lengths, self-tapping screws, and speed clips; vehicle-specific brackets, adapters, or harnesses may still be needed depending on the application. Use an amplifier or receiver compatible with a 4-ohm speaker load and the 20-watt RMS rated input.
