Product details
Sound Field Enhancer design
Kenwood builds the KFC-1666S with its Sound Field Enhancer to improve sound quality and an enlarged magnet circuit for clear sound. The 6-1/2-inch (160 mm) woofer uses a silver polypropylene cone with a cloth surround and a 220 g ferrite magnet, and a 1-inch (25 mm) silver balanced dome tweeter with a neodymium magnet handles the highs.
Power and response
Each speaker handles 30 watts RMS and 300 watts peak at 4 ohms. Sensitivity is 90 dB at 1 watt/1 meter, and frequency response runs from 40 Hz to 22 kHz.
Shallow fit
Kenwood lists only 5/16 inch (8 mm) of mounting height, measured as tweeter height, so the speakers fit a wider selection of cars. The cutout diameter is 4-7/8 inches (123.5 mm) and the mounting depth is 1-11/16 inches (43.2 mm). Each speaker measures 6-11/16 inches (170 mm) across with the grille and 6-5/16 inches (159.8 mm) without it, and weighs about 1.4 lb with the grille.
Included hardware
Kenwood includes two grilles, eight 4 x 25 mm tapping screws, eight speed nuts and two 0.3 m speaker cords. Before you install, check the mounting depth and the cutout size against the speaker location in your vehicle.
