Product details
3-1/2-inch dual-cone dash speakers
Kenwood designed the KFC-835C for 3.5-inch dash applications as a replacement for worn factory speakers. Each speaker uses a water-resistant cone with a whizzer cone that extends the high-frequency response. The speakers are sold as a pair for left and right dash openings.

Power and response
Each speaker handles 10 watts of rated input power and 40 watts peak. Sensitivity is 89 dB at 1 watt/1 meter, and frequency response runs from 96 Hz to 20 kHz. Those figures come from Kenwood’s official product page; retailer pages sometimes list different RMS numbers that are not used here.
Design details
The dual-cone layout puts a whizzer cone in front of the main water-resistant cone so the speaker can cover both mid and high frequencies without a separate dome tweeter. Kenwood positions this model for dash use where a shallow, compact speaker is needed.
Fit
Confirm that your vehicle has a 3-1/2-inch dash opening before ordering. Kenwood’s official page for this model does not list a cutout diameter, mounting depth or impedance, so measure the factory location carefully and compare it to the physical speaker before you install. Do not rely on retailer cutout charts that Kenwood does not publish for this model.
