JL Audio C5-650cw Getting Started, Crossover Network Installation, Crossover Network Adjustment

GETTING STARTED

•Turn off the audio system. It is also advisable to disconnect the negative (–) terminal of your vehicle’s battery whenever performing installation work.

•Before cutting, drilling or inserting any screw, check clearances on both sides of the planned mounting surface. Also check for any potential obstacles, such as window tracks and motors, wiring harnesses, etc. Check both sides of the

vehicle, many vehicles are not symmetrical!

•Always wear protective eyewear.

CROSSOVER NETWORK INSTALLATION

The crossover networks supplied with your C5 System should be installed in a dry location inside your vehicle. DO NOT INSTALL THEM INSIDE OF A DOOR! Doors often get wet on the inside, which can damage your crossover networks and could potentially damage your entire sound system. The crossovers can be screwed into a solid surface via two holes located under the protective cover of the case. To access these holes, simply squeeze the sides of the cover while gently pulling the cover away from the base. Make sure that your mounting location will not cause damage to wiring, fuel lines, brake lines or any other vital component of your vehicle. Once you have screwed the case in and made your connections, snap the protective cover back into place.



!! WARNING

It is absolutely vital that your component system is connected as shown in this manual. Failure to connect the system as shown may result in damage to your speakers which is NOT covered under warranty.

Do not substitute different crossover networks into your C5 System. Do not use crossover networks intended for different C5 models.
