1. Connect the INPUT terminals of the crossover to the speaker output of your head unit or amplifier.
2. Connect the WF (Woofer) terminals of the crossover to the JBL 6.5-inch woofer.
3. Connect the TW (Tweeter) terminals of the crossover to the JBL 0.75-inch tweeter.
4. Secure all connections using spade clips or by soldering and insulating with electrical tape or heat shrink tubing.

Note: Specific wiring colors may vary. Always match positive (+) to positive (+) and negative (-) to negative (-).

4. Operation

4.1 Initial Power-On

After installation, reconnect the car battery. Turn on your car's audio system. Start with the volume low and gradually increase it to ensure all speakers are functioning correctly and without distortion.

4.2 Audio Settings

• Balance and Fader: Adjust these settings on your head unit to ensure sound is evenly distributed throughout the vehicle.
• Equalizer (EQ): Use your head unit's equalizer to fine-tune the sound to your preference. Start with a flat EQ and make small adjustments.
• Gain Settings: If using an external amplifier, ensure the gain is set correctly to prevent clipping and speaker damage. Consult your amplifier's manual for proper gain adjustment procedures.

4.3 Break-in Period

Allow a break-in period of approximately 20-30 hours of normal listening at moderate volumes. This allows the speaker components to loosen up and achieve their optimal sound performance.

5. Maintenance

5.1 Cleaning

To maintain the appearance and performance of your speakers, periodically wipe them with a soft, dry cloth. Avoid using harsh chemicals, abrasives, or excessive moisture, which can damage the speaker cones or grilles.
