TWEETER PLACEMENT CONSIDERATIONS

A component system gives you the ability 

to place the woofer and tweeter separately in 
your vehicle interior. This can be good or bad, 
depending on how it’s done. As a general rule, 
the tweeters should be placed relatively close 
to the woofers for best tonal balance and most 
coherent imaging (the closer, the better). Any 
separation greater than 8 inches (20 cm) is likely 
to result in degraded sound quality. 

Avoid placing tweeters where they 

will be blocked by objects in the interior 
of the car (including seated occupants). 
When selecting a mounting location, look 
at both sides of the car to make sure that 
this location is clear on both sides. 

You can always experiment with tweeter 

placement before committing to a final 
mounting location. Simply connect the rest of 
the system and allow plenty of wire length for 
the tweeters. Using hook and loop fastener or 
similar material, attach the tweeters in different 
locations until you find the one where they 
perform best.

TWEETER PROTECTION

The C1 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 INSTALLATION

The crossover networks supplied with 

your C1 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. Use plastic cable ties or a similar 
fastener to securely mount each crossover to 
avoid coming loose in the event of a collision, 
sudden jolt or repeated vibrations during 
normal use. Make sure that your mounting 
location will not cause damage to wiring or 
any other vital component of your vehicle.
