The correct choice of the amplifier, its settings and enclosure design prolongs the lifetime of your subwoofer. You should
select an amplifier with a nominal power below the nominal power of the subwoofer. Proper coordination of the head unit (HU)
with the amplifier will provide clean, undistorted signal fed to the subwoofer, which prevents overheating and voice coil damage.
Like any other speaker the subwoofer has moving and stationary parts. We strongly recommend that the moving parts of the
subwoofer should be warmed up at the beginning of operation. Be extra careful when warming up the parts. Warm up the
subwoofer using musical material for 40 hours at medium power. If you feel strange smell during operation at maximum volume,
you should lower the volume of the subwoofer and let the device to cool down at a low volume.
Recommended settings of the amplifier and HU: Volume of HU should not exceed 80%. The amplifier sensitivity should be set
to 50%, subsonic filter frequency (Subsonic) should be set to 5 Hz below the port settings. For example, if you configure the port at
30 Hz, Subsonic should be set to 25 Hz. The low pass filter LPF (the filter that cuts all frequencies above those set for the filter)
should be set to 63-80 Hz, bassboost should be set to 0.
