CROSSOVER WIRING & MOUNTING
The crossover can be mounted in almost any location inside the vehicle. Recommended
places are: Inside the door, under the carpet in front of the door angles, under the dash-
board a.s.o. Just make sure not to install the crossover units where they may be exposed
to dirt or excessive moisture / water. Connect the tweeter wires and the main wires coming
from the amplier or head unit to the crossover. Maintain polarities all the way – double
check for correct connection. It is very important to make sure that all the connections are
electrically in phase, which means positive wire (+ or red) is connected to positive termi-
nal, and negative wire (- or black) is connected to the negative terminal. Reverse polarity
connections of the tweeter will cause sharp sound and a messed up front staging.
If longer distances from the amplier to the crossovers have to be overcome, use good
quality speaker cables with a minimum cross section of 2.5 mm². Failure to do so will
affect sound quality in a negative way.
X-OVER ADJUSTMENTS
All AXTON component set crossovers come with two adjustment options that allow you to
tailor the sound by setting slide switches on the pc board inside the housing, to compen-
sate for different mounting locations of the speaker units, as follows:
Tweeter level
As a general rule of thumb, the -3 dB position is best for tweeters that are mounted very
close to the listener’s head like window triangles or top of the door panels.
The -0 dB position is usually the setting that provides a good tonal balance for most in-
stalls. It is recommended for the most tweeter positions.
Attention: The tweeter attenuation must be chosen identically on both crossovers. After
completing the settings of tweeter attenuation and polarity, you can mount the crossover
in place and reinstall all the other panels / factory grilles a.s.o. Your installation is now
complete and therefore ready, to be checked out.
TESTING THE INSTALLED SYSTEM
Slowly turn up the volume of your head unit and listen for distorted sounds. If everything
appears to be okay and it just sounds right, check out the speaker balance of the left and
right side by adjusting the balance control of your head unit. Shifting the balance to the left
channel should provide you with sounds coming solely from the left speaker system, while
shifting the balance to the right should do the same for the right speakers. If anything
appears to be wrong, you must recheck the wiring of the x-overs, the amp or the mid/
woofers.
