Low - frequency information for subwoofer only.
High efficient power

Stiffly regulated PWM power supplies.
MOSFET switches maintain rated power over a wide range of battery voltages.

Adjustable from 50Hz to 150Hz with a slope of 24dB per octave.
This allows for the adjustment of the upper point of the frequency bandwidth
and the respective subwoofer.

Adjustable from 15Hz to 40Hz with a slope of 24dB per octave.
This allows for the attenuation of frequencies that are mostly inaudible and
cause unnecessary strain on the amplifier.

CLASS-D DESIGN

POWER SUPPLIES

LOW PASS FILTER

Protection against thermal, Overload and short circuit conditions.

This amplifier come complete with a compact remote GAIN CONTROLLER
which can be conveniently mounted on or under the dashboard of your car.
