INSTALLATION
Should you install the WDX amplifiers by yourself, please read the owner’s manual very carefully. Before you start your installation, please take all steps into consideration, or you can have a DB Drive or DB Research’s authorized dealer check the installation and help install your car audio system.
MOUNTING PREPARATION
Disconnect the negative ( – ) battery cable before mounting your WDX amplifier or making any connections. Check the battery and alternator ground ( – ) connections. Make sure they are properly connected and free of corrosion before selecting a mounting location. Please also take into consideration cooling efficiency and safety
MOUNTING PREPARATION
COLLECTIVE HEAT MANAGEMENT
The WDX amplifier uses a specially designed heat radiation heatsink to avoid excessive heat from WDX circuitry. For better heat disipitation, it is recommended to find the mounting location where you can install WDX where the heatsink fins have better air flow. For safety, you have to find a dry, well ventilated location. Before mounting, be sure the location and drilling of pilot cables will not present a hazard to any cables, control cables, fuel lines, fuel tanks, hydraulic lines or other vehicle systems or components.
+12V, GND, REM CONNECTION
A) 12V ( POWER CONNECTION )
Before mounting WDX amplifiers, disconnect the negative ( – ) wire from battery to protect any accidental damage to the amplifier and the audio system. WDX 100.4, WDX 200.4, WDX 300.4, WDX 5500.5, WDX 1000.1, WDX 1500.1, WDX 2000.1, WDX 3000.1 are designed to use, at a minimum, 4 gauge power and ground cables. WDX 4000.1, is designed to use, at a minimum, 0 gauge cables. Connect the power cables to power terminal labeled as + 12V. WDX amplifiers are not equipped with fuses so you need to install external fuses.
| MODEL | FUSE |
| WDX 1000.1 | 60A |
| WDX 1500.1 | 90A |
| WDX 2000.1 | 120A |
| WDX 3000.1 | 200A |

| WDX 200.4 | 50A |
| WDX 300.4 | 80A |
| WDX 5500.5 | 60A |
RECOMMENDED EXTERNAL FUSES
In order to install external fuses, connect one end of the fuse holder to the power cable and the other end of fuse holder within 18in of the positive battery terminal, using the same cable gauge. This fuse location will protect the system and the vehicle against the possibility of a short circuit in the power cable. Be sure to use fuses and fuse holder adequate for the current draw application.
B) GND ( GROUND CONNECTION )
Locate a secure grounding connection as close to WDX amplifiers as possible. Make sure the location is clean and provides a direct electrical connection to the frame of the vehicle. Connect one end of a short piece of the same gauge cable as the power cable to the grounding point. Run the one end of the cable to the grounding point. Run the other end of the cable to the mounting location. Connect the ground cable to the screw terminal labeled as GND.
C) REM ( REMOTE CONNECTION )
Run a remote turn on cable from the head units remote switched + 12V output.
WDX +12V, GROUND, REMOTE CONNECTION DIAGRAM.
SPEAKER CONNECTION
DB Drive recommends to use a minimum of 12 gauge speaker connecting cables. Run 12 gauge speaker connecting cables from your speakers to WDX amplifier’ s mounting location. Keep speaker cables away from power cables and WDX amplifier’s input cables. Use grommets anywhere the cables have to pass through the holes in the metal frame or sheet metal. Connect to the speakers according to the type of the terminals on each speaker. Strip 3/8″ of insulation from the end of each cable and twist the cables strands together tightly. Make sure there are no stray strands that might touch other cables or terminals causing a short. Crimp spade lugs over the cable ends or tin the ends with solder to provide a secure termination. Connect the cable ends to WDX amplifiers as shown on speaker system diagrams.

TROUBLESHOOTING
NO SOUND ( NO OUTPUT )
- Check all connections, cables’ routing, short and voltage at WDX amplifiers and headunit.
- Check external fuses. If any are blown, replace with new one.
- Check whether speakers work well. You can test speakers by connecting to another amplifier.
PROTECTION
- Please check overload, overheat ( thermal ), short, voltage and DC offset.
- 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.
- If WDX amplifier shuts down due to overheat, reset by turning off the remote input and allowing time to cool down.
Please make sure there are no airflow obstructions around WDX amplifiers to prevent thermal protection. - WDX 100.4, WDX 200.4, WDX 300.4, WDX 5500.5, 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
- Please check speaker polarities .
WHINING NOISE
- Engine noise is caused by poor grounding of WDX amplifiers, head unit battery, alternator, or other components. Please check all grounding connections.
