Mid/Woofer Installation; Crossover Wiring - Reference RA16RF Installationshandbuch

MID/WOOFER INSTALLATION

You can install the Radical Audio mid/woofers directly to the factory speaker
mounting holes, because their Euro-DIN basket bolt hole configuration will fit to
a great variety of European and Asian cars .
Remove the plastic grille (front door) and unscrew the factory installed 16cm
1
fullrange speaker unit .
Place the Radical Audio Inc . mid/woofer over the mounting hole and see
2
if the existing screw mounting holes and the basket mounting holes align
properly . If not, you have to drill new screw mounting holes! Double check
if the mounting clearance is sufficient to fit the mid/woofers! Otherwise you
risk to impair the window or door function of your vehicle .
If the available clearance between the surround of the mid/woofer and the
3
original factory plastic grilles is big enough, you can use the "MassBelt"
steel rings supplied with this set . The rings are "sandwiched" between the
mounting hole and the mid/woofer unit .
Attach the wires to the mid/woofer unit . Double-check for correct speaker
4
polarity! Place the speaker into the mounting hole and screw the speaker
into place . Don't forget to use the supplied foam gasket for an airtight seal!
Remount the factory plastic grilles . While doing this, check for the clearance
5
between surround and backside of the grille . You will need at least 6mm of
clearance between surround and the backside – or the surround may hit the
grille when the speaker system is pushed hard .
Note If one of the mid/woofers is wired out of phase (inverted), the
➔
resulting sound is very diffuse and the bass is almost nonexistent!

CROSSOVER WIRING

Wire the crossover unit as shown in the schematic diagram on the next page .
1
Be sure to maintain speaker polarity at the input/output terminals of the
crossover!
Fix the crossover in place with the provided self-tapping screws – and avoid
2
installing the crossovers in locations where they could be exposed to water,
excess humidity or other fluids .
Note It is best to have the crossovers mounted in a location that allows easy
➔
access . It may be necessary to re-adjust tweeter attenuation and presence level,
after the speaker break-in period .
