Choosing your cables

As they directly affect the system’s damping factor, the cables used to connect the speaker

are extremely important; the following table indicates the cable section (gauge) we recommend

according to the length and power applied.

The table refers to continuous power

into a 4 Ohm load. When the load

decreases, the size of the cable

needs to be proportionally increased.

In series - in parallel patterns

Below, please find some examples of connections: single, parallel, series/parallel.

Tuning

After you finish installing the speakers in your vehicle, it is recommended to spend some time

to tune the amplifiers (if present), and to adjust the HFC and tweeter level controls located

on the crossover.

An inherent acoustical problem found in the vehicle environment is the different orientation

of the left and right channel speakers in reference to the listening point, changing the perceived

response, extension and phase of the reproduced signal. The HFC (High Frequency Contour)

is a proprietary circuit that effectively eliminates this problem. If you wish to optimize the response

for the driver, set the EJ (Easy Jumper) on the crossover for this channel to “HFC ON”, and set

the EJ (Easy Jumper) on the passenger channel to “HFC OFF”. The left channel response will now

be compensated for and the acoustic image perceived by the driver will gain a correct timber,

naturalness and power. To optimize the system for the passenger, set the jumpers opposite to

what has been described.

Caution: Turn the power off on the audio system before making these changes.
