Kenwood KFC-1613MRB 6.5" Marine/Motorsports Speakers

The Kenwood KFC-1613MRB is a pair of 6.5-inch 2-way coaxial speakers designed for marine and motorsports audio systems. It provides a practical upgrade for boats, ATVs, UTVs, golf carts, motorcycles, and other open-air installations where conventional car speakers may not be suitable. Its 4-ohm impedance allows connection to compatible marine receivers, powersports source units, or external amplifiers.

These speakers use a water-resistant polypropylene woofer cone and water-resistant balanced-dome tweeter to support outdoor listening in demanding environments. A rubber surround helps the woofer remain flexible and durable during regular use. The UV-resistant grille is intended to help protect the speaker assembly from sun exposure.

The KFC-1613MRB is rated for 30 watts RMS input power and 100 watts peak input power. Its 87 dB sensitivity and 60 Hz to 20 kHz frequency response make it suitable for clear full-range playback in compact outdoor audio systems. For best results, match the speakers with a clean, appropriately powered 4-ohm amplifier or receiver channel.

Its coaxial 2-way design combines the woofer and tweeter into one round speaker assembly, simplifying installation where space is limited. The balanced-dome tweeter is mounted separately from the woofer cone, supporting high-frequency reproduction while maintaining the speaker's weather-resistant construction. This design is useful for replacing existing 6.5-inch marine or powersports speakers with a similar mounting format.

The pair is designed for flush mounting with a 5-inch cutout and a 2-5/16-inch mounting depth. Stainless mounting hardware and speed clips are included for installation. Before purchasing, confirm available panel depth, cutout size, mounting-hole alignment, and the speaker color associated with the exact SKU being ordered.

Key Features

• 6.5-Inch Coaxial Design: Combines woofer and tweeter in each speaker.
• 30W RMS Rating: Matches compatible low- to moderate-power audio systems.
• 100W Peak Input: Supports short musical peaks during playback.
• Water-Resistant Drivers: Helps suit marine and motorsports applications.
• UV-Resistant Grille: Helps protect the visible speaker surface outdoors.
• 4-Ohm Impedance: Works with many marine receivers and amplifiers.

Design & Installation

The KFC-1613MRB uses a water-resistant polypropylene cone, rubber surround, balanced-dome tweeter, and UV-resistant grille. These materials are selected for installations exposed to outdoor conditions, including sunlight and moisture. The fixed-grille coaxial layout keeps the tweeter integrated within the speaker assembly.

Plan for a 5-inch cutout and at least 2-5/16 inches of mounting depth behind the panel. Connect each speaker to a compatible amplifier or receiver output, observing positive and negative terminal polarity. The package includes twelve 4 x 25 mm mounting screws and twelve speed clips for installations that can use the supplied hardware.
