DX_SERIES – AMPLIFIER’S CONTROL & CONNECTION
INSTALLATION
In case you install the DX-Series amplifiers by yourself, please read the owner’s manual very carefully. Before you start your installation, please consider all steps, or you can have a DB Drive or DB Research’s authorized dealer check the installation and help set your car audio systems.
MOUNTING PREPARATION
- Disconnect the negative(-) battery cable before mounting your DX-Series 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
- The DX-Series amplifier uses a specially designed heat radiation heatsink to avoid excessive heat from the DX-Series circuitry. But for better heat dissipation, it is recommended to find the mounting location where you can install the DX-Series where the heatsink fins have better air flow. For safety, you have to find a dry well 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. 3-3. +12V, GND, REM CONNECTION
A) 12V ( POWER CONNECTION )
- Before mounting DX-Series amplifiers, disconnect the negative (-) wire from the battery to protect against any accidental damage to the amplifier and the audio system. DX-A4090 and DX-A1005 are designed to use, at a minimum, 4-gauge power and ground cables. DX-A601 & DX-A1201 are designed to use, at a minimum, 0-gauge cables. Connect the power cables to the power terminal labeled as + 12V.
B) GND ( GROUND CONNECTION )
- Locate a secure grounding connection as close to the DX-Series 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 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 unit’s remote switch 12V output.
DX-SERIES +12V, GROUND, REMOTE CONNECTION DIAGRAM
SPEAKER CONNECTION
DB Drive recommends using a minimum of 112-gauge speaker connecting cables. Run 12-gauge speaker connecting cables from your speakers to the DX-Series amplifier’s mounting location. Keep speaker cables away from power cables and the DX-Series 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 terminals on each speaker. Strip 3/8″ of insulation from the end of each cable and twist the strands of the cable 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 the DX-Series amplifiers as shown on the speaker system diagrams.
A CAUTION !!
DX-A601 and DX-A1201 amplifiers minimum impedance is 1 ohms.

TROUBLESHOOTING NO SOUND ( NO OUTPUT )
- Please check all connections, cables’ routing, shorts, and voltage at the DX-Series amplifiers and headunit.
- Please check the external fuse at the battery. If any are blown, replace them with a new one.
- Please check whether the 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 ohms stereo or 4 ohms mono.
- Minimum working impedance for all Class D mono amplifiers is 1 ohm for single unit and 2 ohm for linked operation.
- If DX-Series 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 DX-Series amplifiers to prevent thermal protection. 4) DX-A601 and DX-A1201 have voltage operation of 9V~16V
- If the Voltage is out of range of the above, DX-Series amplifiers will be protected.
POOR BASS RESPONSE
- Please check speaker polarities
WHINING NOISE
- Engine noise is caused by poor grounding of DX-Series amplifiers, headunit, other components, battery or alternator, so please check all grounding connections.
