Kenwood KFC-6998RS 6x9-Inch 5-Way Car Speakers

The Kenwood KFC-6998RS is a pair of 6x9-inch 5-way car speakers designed to replace compatible factory-installed oval speakers. They provide a full-range upgrade path for vehicles whose original speakers have lost clarity, output, or bass definition. With a 4-ohm impedance and 150W RMS power rating, they can be matched with compatible factory or aftermarket audio systems.

These speakers use a polypropylene woofer cone with Kenwood's Diamond Array Pattern, paired with a urethane surround. This construction is intended to support controlled cone movement and reduce distortion during playback. The oval 6x9-inch format is well suited to common rear-deck, door, and factory speaker locations that accept this size.

A 1-3/4-inch balanced-dome tweeter works with a 4/5-inch ceramic super tweeter and two 1/2-inch ceramic super tweeters. The multi-driver design is built to reproduce upper-frequency detail alongside the woofer's midrange and lower-frequency output. Kenwood rates the KFC-6998RS for a frequency response of 58Hz to 22kHz.

Kenwood's Acoustic Sound Harmonizer manages woofer sound waves through the tweeter-panel openings to help produce a smoother, more natural response. The speakers also use a Sound Field Enhancer tweeter shape intended to strengthen forward sound and widen the high-frequency sound field. These features help make the speaker a practical choice for listeners seeking a more detailed presentation from a conventional full-range replacement speaker.

For installation, the KFC-6998RS has a 5-7/8 by 8-5/8-inch cutout requirement and a 3-3/16-inch mounting depth. Its low 1/2-inch tweeter height is designed to support fitment in many factory locations. Included grilles, hardware, speaker wire, and adhesive tape provide useful installation accessories, although vehicle-specific adapters or harnesses may still be needed.

Key Features

• 5-Way Driver System: Combines a woofer, balanced-dome tweeter, and three super tweeters for broad full-range reproduction.
• 150W RMS Power: Handles substantial continuous power when paired with a properly matched compatible amplifier.
• Diamond Array Woofer Cone: Polypropylene cone pattern helps reduce distortion and supports clear, controlled playback.
• Acoustic Sound Harmonizer: Controls woofer sound waves through the tweeter panel for smoother, more natural sound.
• Sound Field Enhancer: Tweeter shape is designed for stronger forward sound and wider high-frequency dispersion.
• Factory-Location Fit: Low tweeter height helps the speaker fit in many compatible factory mounting locations.

Design & Installation

The KFC-6998RS uses a black polypropylene woofer cone, urethane surround, steel basket, and black-painted steel top plate and yoke. Its magnetic circuit uses a ferrite woofer magnet, while the tweeter also uses a ferrite magnet. The black-painted yoke and plate are designed to release heat efficiently within the magnetic circuit and support voice-coil durability.

Confirm available mounting depth, cutout dimensions, and vehicle-specific mounting provisions before purchase. Connect each speaker to a compatible 4-ohm speaker output and use an amplifier or head unit whose setup is appropriate for the speaker's published power rating. The supplied grille assemblies, tapping screws, washers, speaker cords, and adhesive tape can assist with installation, but vehicle-specific brackets or wiring adapters are not listed as included.
