4. TROUBLE SHOOTING
NO SOUND ( NO OUTPUT )
1) Check all connections, cables' routing, short and voltage at WDX amplifiers
and headunit.
2) Check external fuses. If any are blown, replace with new one.
3) Check whether speakers work well. You can test speakers by connecting to another amplifier.
PROTECTION
1) Please check overload, overheat ( thermal ), short, voltage and DC offset.
2) Minimum working impedance for 4 channel amplifiers is 2 ohm stereo or 4 ohm mono
Minimum working impedance for all Class D mono amplifiers is
1 ohm for single unit and 2 ohm for linked operation.
3) If WDX amplifier shuts down due to overheat, reset by turning off the remote input and
alowing time to cool down.
Please make sure there are no airflow obstructions around WDX amplifiers to prevent
thermal protection.

WDX
300.4,
WDX

WDX
1000.1,
WDX
1500.1,
WDX
2000.1,
WDX
3000.1, and
WDX
4000.1 have voltage operation of 12V~15V.
WDX amplifiers will protect if voltage is out of range.
POOR BASS RESPONSE
1) Please check speaker polarities .
WHINING NOISE
1) Engine noise is caused by poor grounding of WDX amplifiers, headunit,
battery, alternator, or other components. Please check all grounding connections.
