How to use

Install the speaker into a compatible factory or aftermarket mounting location using appropriate screws and wiring.

Usage recommendations

For best results, pair the Kenwood KFC-S1756 with an amplifier or head unit that supplies power within the speaker’s rated range and use sound-deadening materials in door panels to reduce vibrations and improve midrange clarity. Avoid driving the speaker at continuous maximum power to prevent overheating or cone damage.
