Car speaker Kenwood KFC-S1766 round 2-way 16 cm (176 mm) 4Ω 30W RMS 300W peak, sensitivity 89 dB

The Kenwood KFC-S1766 Round 2-way 300 W car speaker offers a balance of compact dimensions and clear audio reproduction for vehicle installations. With a rated power of 30 W and peak handling up to 300 W, this 17.6 cm (176 mm) round speaker is designed to fit many standard vehicle speaker locations while providing improved midrange clarity and defined high frequencies. The shallow mounting depth makes it suitable for installations where space behind the door or panel is limited.

Advantages

The Kenwood KFC-S1766 delivers a two-way configuration that separates mid/bass and treble duties for clearer instrument and vocal detail. Its compact width and shallow mounting depth simplify installation in tight spaces without major modifications. The speaker is engineered to handle short-term peak power while operating efficiently at its rated power, resulting in reliable day-to-day performance and consistent sound across typical in-car listening volumes.

Suitable for

• Replacing factory door or dash speakers in compact and mid-size cars
• Upgrading a basic factory system for clearer vocals and treble
• Installations with limited mounting depth behind panels
• Retrofit projects where standard 176 mm round mounting is available

How to use

Install the speaker into a compatible 176 mm round mounting location in the vehicle door, dash, or rear parcel shelf. Ensure the mounting depth of at least 4.42 cm is available and remove any obstructions behind the panel. Secure the speaker with the appropriate screws and gaskets to avoid vibrations and air leaks. Connect the positive and negative speaker leads to the vehicle wiring, observing correct polarity to preserve imaging and phase. If the vehicle amplifier exceeds the speaker's rated power, use appropriate gain settings or a crossover to prevent distortion and potential damage.

Usage recommendations

Pair the Kenwood KFC-S1766 with a suitable head unit or compact amplifier that matches or modestly exceeds the speaker's rated power to achieve balanced audio. Use proper mounting hardware and sealing to minimize rattles. For improved low-frequency response, consider adding an aftermarket subwoofer or selecting door treatments and sound-damping materials.
