Setup and Installation
The Kenwood KFC-S6966 speakers are designed for flush mount installation in vehicle audio systems. Proper installation is crucial for sound quality and speaker longevity.
- Preparation: Disconnect the vehicle's battery. Remove existing speakers or trim panels to access the speaker mounting locations.
- Mounting Location: Identify suitable mounting locations, typically in door panels, rear decks, or custom enclosures. Ensure sufficient depth and clearance for the speaker magnet and frame. Refer to the dimensions diagram below.
- Cutting Template (if necessary): If replacing smaller speakers or installing in a new location, use the provided template (often found on the speaker box) to mark and cut the opening. The speaker basket is wide, so ensure the opening accommodates the full speaker diameter.
- Speaker Placement: Position the speaker in the opening. If the speaker basket interferes with the vehicle's structure, a speaker spacer may be required to provide adequate clearance.
- Wiring: Connect the speaker wires from your amplifier or head unit to the speaker terminals. Ensure correct polarity (+ to + and - to -) for optimal sound. The positive terminal is usually marked with a '+' or a larger terminal.
- Securing Speakers: Use the supplied mounting screws to firmly secure the speakers in place. Do not overtighten.
- Grille Installation: Attach the speaker grilles over the installed speakers.
- Final Steps: Reinstall any removed trim panels. Reconnect the vehicle's battery.
