GETTING STARTED
•Turn off the audio system. It is also advisable to disconnect the negative
•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 C3 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.
TWEETER PROTECTION
The C3 crossover networks are equipped with an advanced electronic tweeter protection circuit designed to minimize the possibility of tweeter failure. This electronic device monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Should this occur while listening to the audio system, simply reduce the volume for a few seconds and the protection circuit will reset itself automatically.
CROSSOVER NETWORK ADJUSTMENT
The crossover networks have been designed to allow tonal adjustments to the upper midrange response and tweeter level. These adjustments make it possible to
ADJUSTABLE MIDRANGE PRESENCE
Your C3 crossover networks provide a unique midrange presence control, located under the cover. The midrange presence is selectable via a set of pins and allows for three settings. These settings affect the amplitude of the upper midrange response of the C3 component woofer. We recommend that you begin your listening in the “REF” (Reference) and adjust up or down as needed to compensate for mounting location, orientation or personal taste.
ADJUSTABLE TWEETER LEVEL
C3 crossover networks also provide four levels of tweeter adjustability designed to compensate for different mounting locations, vehicle interiors and personal taste. These levels are selectable via a set of pins located under the clear cover of each crossover case. We recommend that you begin listening in the “REF” (Reference) position. To find the optimum tonal balance in your installation, experiment with alternate tweeter level settings by moving the pins. It is safe to switch jumpers while the system is playing.
