POSITIONING AND SECURING THE SUBWOOFERS
IMPORTANT: Please ensure when fitting illuminated components that for
purposes of traffic safety while driving no light shines outside the vehicle which
could have an adverse effect on other road-users.
Ensure that the subwoofer cabinet rests on an even surface. The cones (and, where
applicable, the bass reflex tube) should not be placed directly against the car's interior
walls.
Make sure that the subwoofer is secured in such a way that it cannot slip or slide.
Damage resulting from sudden changes in speed (e.g. hard braking) is not covered
under the terms of our guarantee.
CONNECTING TO THE POWER AMPLIFIER (FIG. 1)
The subwoofer should be connected to an external power amplifier in every case. This
can provide the required electrical power and create corresponding dynamic reserves.
The relevant instructions also contain the customized connection diagram for the
operation of a subwoofer.
The basic equipment of a power amplifier also includes an active crossover switch (low-
pass) to keep undesirable mid-tone ranges away from the subwoofer.

ADDITIONAL PASSIVE FILTERS (FIG. 2)
Should you not have any active filter switching available (e.g. use of a mono-block or tri-
mode two-channel power amp), this function has to be performed by a passive crossover.
Please select your subwoofer's cutoff frequency and wire the components as follows.
