IMPORTANT NOTES
Choose a suitable location for your soundsystem, that neither the driver’s field of vision nor the
security of the inmates will be affected. This stands also for airbag-zones and safety belts. The per-
manent temperature of the location should not be lower than 5°C and not higher than 50°C. Protect
the device from moisture and humidity.
Ensure that your subwoofer enclosure will not get loose during the drive and hurt someone in the
passenger cabin. It is recommended, that you mount the subwoofer enclosure with suitable belts or
any other mounting solutions in the trunk area.
Please observe not to damage any serial components of your vehicle (airbags, wires, gastank etc.)
during the installation of your soundsystem by drilling or any other operations.
For your personal concerns you should choose a appropriate sound level for the subwoofer enclo-
sure, that neither the roadworthy of the driver nor his concentration will be disturbed, that he is able
to notice possible traffic noises and acoustical warning signals.
Modern car audio soundsystems provide very high acoustic pressure beyond the 100 dB mark.
Please observe in this case, that permanent use of high sound levels may cause damage to your
ability of hearing.
Please ensure by any means the correct polarity of all connections. Faulty installed and connected
devices may get damage the vehicle and the device permanently.
Please check in any case the operation guide or wiring manual of your amplifier which you’d like to
use for the soundsystem.
Never connect the speaker terminals with the 12 Volt power supply, otherwise the speakers may
get damaged.
POWER RATING
ESX subwoofer enclosures are designed for high bass levels. Anyhow it is possible, that unsatisfy-
ing sound characteristics could be caused by too low or too high amplifier power. In certain circum-
stances this even can cause a damage to the loudspeakers.
It is recommended to choose rather a more powerful amplifier (ca. 15-20% more Watts RMS than
the max. RMS power rating of the woofer) and to use the amplifier not at the maximum output level
(low distortion factor, good sound characteristics). A weaker amplifier at the maximum level causes
worse sound characteristics due to the higher distortion factor.
Never crank up the output volume of your amplifier to the maximum level or run the amplifier into
the clipping range. If the sound is distorted and not clean, turn back the level until the distortions
disappear.
ESX subwoofer enclosures have no integrated limiter or clipper, which is limiting the level upwards.
Overamplified bass peaks leads inevitably to a burn out of the voice coil of the woofer. A burn out of
the voice coil, caused by clipping/overamping is not covered by the usual warranty.
