MId/WooFer MountIng
Remove the factory grilles of the front door and remove – if applicable - the factory installed full
range speakers or mid/woofers . Depending on the car brand and type, it is sometimes unavoidable
to remove the complete doorpanels to gain full access to the speaker openings .
If this is the case, you should buy some spare plastic clips for remounting of the door panels after
your install is complete, as these clips tend to break quite easily .
Note that a tight fit of the door panels is important, since door panels with a loose fit swallow bass
energy and they may add unwanted rattling and distortions to the sound of your speaker system .
Before you proceed to mount the EMPHASER mid/woofers, check the available installation depth
with both front windows down .
Connect the speaker wires to the mid/woofers and route it to the location where the crossovers are
going to be located and installed . Pay close attention to the polarity imprints on the terminals and
wires when connecting the mid/woofers .
When you tighten up the screws to mount the mid/woofers in place, be sure to check for an airtight
seal and good fit of the basket rim to the mounting surface . You can now re-install the factory plastic
grilles or the complete door panels .
If you have chosen another location for your woofer/midrange drivers (other than factory cut-outs),
you can also use the speaker protection grilles to avoid any damage to the cones of your mid/
woofers .
X-oVer 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 etc . Just don’t
mount the crossovers in places where they may be exposed to water or moisture . Consider to find a
spot that allows you to fine tune the tweeter attenuation level, after your install is completed .
Connect the tweeter wires, the wires from the mid/woofers and the wires from the amplifier to the
crossover units . Make sure all wires are hooked up with correct polarity, i .e . electrically in phase,
which means positive (+) is connected to positive, and negative (-) to negative .
Out of phase connections, i .e . when a mid/woofer is concerned, will cause very low bass output
and a weird staging .
tWeeter attenuatIon
The tweeter attenuation jumper is located inside the crossover housing on the circuit board . Four
different positions can be selected by moving the jumper to
0db / -2db / -4db / -6db
positions .
0dB will give you a loud high frequency reproduction, while -6dB gives you a very soft sound in
the treble region .
The correct attenuation must be played by ear, as you simply tune the high frequency balance to fit
your personal taste .
attention
: The jumper on each x-over PCB must be set to the same attenuation level .
