MID/WOOFER INSTALLATION
You can install the Radical Audio mid/woofers directly into the factory speaker mounting
holes, because their Euro-DIN basket bolt hole configuration will fit to a great variety of
European and Asian cars.
Caution: Before installation, be sure that the mid/woofers will not interfere with the front
window or door mechanism!
a
Remove the plastic grille (front door) and unscrew the factory installed 13cm or 16cm
fullrange speaker unit.
s
Place the Radical Audio Inc. mid/woofer over the mounting hole and see if the existing
screw mounting holes and the basket mounting holes align properly. If not, you have to
drill new screw mounting holes!
d
If the available clearance between the surround of the mid/woofer and the original
factory plastic grilles is big enough, you can use the "mass-reactance" steel rings
supplied with this set. The rings are "sandwiched" between the mounting hole and the
mid/woofer unit. The advantage is a totally even/level mounting surface, as well as a
considerably increased mass-reactance, audibly reducing unwanted panel vibrations.
f
Attach the wires to the mid/woofer unit. Double-check for correct speaker polarity!
Place the speaker into the hole and screw the speaker into place. Don't forget to use
the supplied foam gasket for an airtight seal!
Attention: Be careful not to bend
the mid/woofer speaker frame when tightening up the screws! The
plastic injection basket may break if the underground is not level or the
mounting screws are tightened up unsymmetrically!
g
Remount the factory plastic grilles. While doing this, check for the clearance between
surround and backside of the grille. At least 6mm of clearance - e.g. distance of
surround to any part inside the plastic grille - is necessary! This allows for proper cone
travel of the mid/woofer. If necessary, cut off plastic parts or reinforcement ribs that
could interfere with surround or cone, when the speaker is in use.
MIDRANGE INSTALLATION
You can install the Radical Audio midrange unit directly into the factory dash board cutout
or else, to cut-outs in the front doors, using either one of both supplied adaptor rings.
C
Ca au uttiio on n:: Before installation, be sure that the midrange units will not interfere with the front
window or door mechanism!
Pre-assemble the midrange unit, by attaching the metal clamps to the speaker. You will
need four clamps for each midrange speaker, and the clamps can be attached as follows:
Click the clamp onto the small rim on the front side of the midrange unit and gently push
down the clamp until it snaps in. Repeat this step for the other three clamps to form a
cross. This pre-assembled midrange unit can now be inserted into the chosen mounting
adapter ring according to the way of mounting. You can now mount the unit to the dash
board, or as described in detail below, into the front doors:
a
Remove the panel you are going to install the midrange unit, to check for proper
clearance behind it. The mounting location for the midrange speaker shall be as much
in front and as high as possible. Mark the main cut-out. The midrange unit with flat
surface mount adapter ring will require a clearance of 30mm behind the panel! Make
sure there are no obstructions behind the spot you choose.
s
Now cut a hole with a diameter of 76 mm, for example using a hole-saw attachment for
your power drill.
