The Kenwood KFC-C6898RS is a pair of 6 x 8-inch oval, 2-way custom-fit car speakers designed to replace compatible factory-installed speakers. They provide a practical upgrade for vehicles whose original speakers have lost clarity, developed distortion, or no longer reproduce music evenly. With a 4-ohm design and 88 dB sensitivity, they are suited to conventional car-audio speaker installations.
These speakers are rated for 81 watts RMS power and 360 watts peak input power. Their 64 Hz to 20 kHz frequency response is intended to cover bass and midrange from the woofer while extending into high frequencies through the integrated tweeter. The result is a full-range speaker option for front or rear factory locations that accept the required oval dimensions.
A 6 x 8-inch polypropylene woofer cone forms the foundation of the KFC-C6898RS design. Its Diamond Array Pattern is engineered to help reduce distortion, while the rubber surround supports controlled cone movement. The steel basket and black-painted steel top plate and yoke provide a durable structure for the driver assembly.
For high-frequency reproduction, each speaker uses a 30 mm balanced-dome tweeter with a neodymium magnet. Kenwood's Sound Field Enhancer tweeter shape is designed to direct sound forward and broaden the sound field at higher frequencies. The Acoustic Sound Harmonizer controls sound waves behind the tweeter panel to support a smoother overall response.
The low-profile tweeter height helps the KFC-C6898RS fit many factory speaker locations, while its custom-fit oval format supports straightforward replacement applications. Verify the available mounting depth, cutout, and vehicle-specific mounting arrangement before installation. These passive speakers can be used with a compatible factory or aftermarket receiver, or with appropriately matched external amplification.
Key Features
- 81W RMS Power Handling: Supports systems delivering up to 81 watts RMS per speaker.
- 6 x 8-Inch Oval Format: Fits compatible factory-style oval speaker locations.
- Polypropylene Woofer Cone: Provides a lightweight, durable cone for full-range playback.
- Diamond Array Pattern: Helps reduce distortion from the woofer cone.
- Balanced-Dome Tweeter: Adds dedicated high-frequency reproduction from a 30 mm tweeter.
- Acoustic Sound Harmonizer: Controls woofer sound waves behind the tweeter panel.
Design & Installation
The KFC-C6898RS combines a black polypropylene cone, rubber surround, steel basket, and black-painted steel top plate and yoke. Its woofer uses a ferrite magnet, while the balanced-dome tweeter uses a neodymium magnet. The low 5/16-inch tweeter height is designed to support installation in many factory locations.
Confirm that the vehicle accepts a 6 x 8-inch oval speaker and provides at least a 5-1/8 x 7-3/8-inch cutout with 2-3/8 inches of mounting depth. The package includes eight 4 x 25 mm tapping screws and two 0.3 m speaker cords; no grille assembly is listed. Use correct polarity when connecting the speaker wires, secure the speakers firmly, and avoid mounting locations where the speaker can interfere with vehicle components.

Will these fit my vehicle?
They are 6 x 8-inch oval custom-fit speakers, but fitment depends on the vehicle's factory opening and mounting arrangement. Confirm a 5-1/8 x 7-3/8-inch cutout and 2-3/8-inch mounting depth, along with vehicle-specific clearance.
Do I need an amplifier for these speakers?
These are passive 4-ohm speakers and require a compatible car-audio power source. They are rated for 81 watts RMS power, so match the source or amplifier appropriately and avoid exceeding the speaker's rated continuous power.
