TROUBLE SHOOTING THE SYSTEM

PROBLEM No Output
Low Output Engine Noise

LOOK FOR
Blown fuse Bad RCA Cable(s) +12V at power terminal +12V at remote terminal Grounding point are clean and tight Head unit’s fader not in center position Master and slave settings
Check level adjustments Bad RCA cable(s) Improper level matching Master and slave settings
Grounding points are clean and tight Ground all components at same point Try different grounding point Bad RCA cable(s) Use high quality shielded RCA cables Low vehicle charging system and/or battery

SOLUTION
Replace Replace Check connection Check connection Check for ground w/meter Set to center position Confirm correct setting
Replace Re-adjust Confirm correct settings
Check for ground w/meter Ground at same point Change for better ground Replace Rejects inducted noise Fix and/or replace

Red protection L.E.D. illumintaed Speaker short
Speaker grounding out
Impedance too low Overheating

Check speakers connection for short circuit Make sure speaker wires do not touch chassis ground Check speaker impedance Check mounting location for adequate air circulation. Speaker impedance too low

FEATURES AND BENEFITS

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 WDX300.4G2, WDX400.4G2 and WDX800.4G2 also offers independent 12dB per octave High Pass and Low Pass X-Over Network.

Bass Boost
For added low frequency performance the amplifiers are equipped with a selectable 6dB-12dB bass boost @ 45Hz

BUILT-IN CROSSOVER
4 Channel: [ WDX300.4G2, WDX400.4G2, WDX800.4G2 ] The WDX300.4G2, WDX400.4G2 and WDX800.4G2 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 crossover switch to HPF and adjust the frequency seng to the desired HPF seng to 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. You must adjust the HPF frequency seng to 50Hz and the LPF frequency seng to the desired Low Pass seng to block out any unwanted high frequencies.
If you wish to run a component midrange on either channels 1-2 or 3-4 set the crossover switch to LP/BP. Then use both HPF and LPF frequency controls to create the desired band pass frequency range.
THESE SETTING CAN BE USE ON CHANNELS 1-2 OR 3-4 INDEPENDENTLY OR FOR ALL CHANNELS

ADJUSTMENTS AND SETTINGS
( WDX1KG2 – WDX2KG2 – WDX3KG2 – WDX5KG2 ) The WDX1KG2, WDX2KG2, WDX3KG2 and WDX5KG2 are equipped with a variable 24db slope Lowpass crossover network and a 24db slope subsonic filter. 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.
REMOTE BASS CONTROL MODULE
( WDX1KG2 – WDX2KG2 – WDX3KG2 – WDX5KG2 )
Before connecting the remote, it will be necessary to find a mounting location that will be easy to access for adjustment. Once you select your mounting location, your mounting location, you will need to run the control wire from the remote to the remote to the amplifier. To avoid possibility of induced noise from the car’s electrical system ( i.e. popping noises or engine noise ), run the cable from the remote to the amplifier away from the car’s electrical wiring.
