GND ( GROUND CONNECTION )
Locate a secure grounding connection as close to OKUR series 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.
REM ( REMOTE CONNECTION )
Run a remote turn on cable from the headunit’s remote swithed +12V output.
3-4. SPEAKER CONNECTION
DB Drive recommends to use minimum 12 gauge speaker connecting cables. Run 12 gauge speaker
connecting cables from your speakers to OKUR amplifier’s mounting location.
Keep speaker cables away from the power cables and OKUR 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 cables strands together tightly. Make sure there are no stray strands that might touch other cables
or terminals and cause a short circuit.
Crimp spade lugs over the cable ends or tin the ends with solder to provide a secure termination.
Connect the cable ends to OKUR competition amplifiers as speaker system diagram.

4. TROUBLE SHOOTING
NO SOUND ( NO OUTPUT )
1) Please check all connections, cables’ routing, short and voltage at OKUR amplifiers and headunit.
2) Please check built-in or external fuses, If it is brown, please repalce with new one.
3) Please check whether speakers work well, you can test speakers by connecting to another amplifiers.
PROTECTION
1) Please check overload, overheat ( thermal ) , short, voltage and DC offset.
2) Minimum working impedance for A7 5000H.1 is 1 ohm for single unit and 2 ohm for linked operation.
3) If the OKUR competition amplifiers are shut 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 OKUR competition amplifier to prevent thermal
protection.
4) A7 5000H.1 has a voltage protection as 8.5 ~ 18volts
If Voltage is out of range as above, OKUR competition amplifiers will be protected.
POOR BASS RESPONSE
1) Please check speaker polaritys.
WHINING NOISE
1) Engine noise is caused by poor grounding of OKUR amplifiers, headunit, other components, battery or
alternator, so please check all grounding connections.
