4. Setup and Installation
Proper installation is crucial for optimal sound performance. The KFC-T40A tweeters are designed for flexible mounting in various vehicle locations.
4.1 Choosing a Mounting Location
Consider locations that provide clear sound projection and do not obstruct visibility or vehicle controls. Common locations include:
- Dashboard corners
- A-pillars
- Door panels (if space permits)
The balanced dome design of these tweeters provides wide sound dispersion, making them less sensitive to precise aiming than some other tweeter types, but aiming them towards the listener can further improve imaging.

4.2 Wiring and Connection
- Disconnect Power: Before making any connections, ensure the vehicle's battery is disconnected.
- Identify Wires: Connect the positive (+) and negative (-) wires from your amplifier or head unit to the corresponding terminals on the tweeter's in-line high-pass filter.
- Connect Tweeter: Connect the output from the in-line high-pass filter to the tweeter. The in-line high-pass filters are essential for protecting the tweeters from low-frequency signals that can cause damage.
- Secure Wiring: Route all wiring safely, away from moving parts, heat sources, and sharp edges. Use cable ties to secure loose wires.
- Test Connection: Once all connections are made and secured, reconnect the battery and test the audio system at a low volume.
