Low Impedance Stability The DB Drive WDX amplifiers includes built-in variable crossovers. The crossover features a variable frequency selection for precise low pass filtering for all mono amplifiers. The WDX300.4, WDX400.4 and WDX800.4 also offers independent 12dB per octave High Pass and Low Pass X-Over Network.

The mono amps also feature a Selectable Bass Boost EQ is set at 45Hz. In some subwoofer enclosure installations it may necessary to use the Phase Shift feature. The Phase Shift button sets the Subwoofer signal between 0 degree setting and 180 degree settings. This will also allow you to fine tune the subwoofer enclosure depending on vehicle location.

Built-in Crossover ( 4 Channel: WDX300.4, WDX400.4, WDX800.4 ) The WDX300.4, WDX400.4 and WDX800.4 amplifier allow you to select the crossover mode (High-Pass, Full Range or Low Pass / Band Pass) and desired crossover point for channels 1-2 and 3-4. For example if you wish to use a 2-way loud speaker on channels 1-2, simply set the block out any unwanted low frequencies. If you wish to run a subwoofer on channels 3-4, simply set the crossover switch to LP/BP.
