Preparation
For safety purposes, install the amplifier in a dry and well ventilated location and make sure no cables
or other harness of the car is interfaced with the mounting location or will present a hazard to the car’s
cable, control cables, fuel lines/tanks, hydraulic lines or other components of the vechicle.
3.2 Power connectors
12V (Power connection)
Before mounting the amplifier, disconnect the negative (-) wire from the battery to protect any accidental
damage to the amplifier or the audio system.
The amplifier is equipped with 0 AWG power and ground terminals.
Connect the power cables to power terminal labeled as + 12V.
The
Dro
is not equipped with fuses, so external fuses are required.
Connect one end of the fuse holder to the power cable and the other end of the fuse holder to the positive
battery terminal within 20 cm of the same cable.
This fuse location will protect the system and the vehicle against the possibility of a short circuit
in the power cable.
Make sure that the fuses and the fuse holder is adequate for the desired application.
GND (Ground connection)
Locate a secure grounding connection as close as possible to the amplifier.
Make sure the location is clean and provides a direct electrical connection to the chassis of the vehicle.
Connect one end of an equal sized cable as the positive cable to the location of ground
It is important that the ground cable is as short as possible, but no longer than 75 cm at maximum.
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 terminal labeled as GND.
REM ( REMOTE CONNECTION )
Run a remote turn on cable from the sw 12V source.
This may be a toggle switch, a relay, the source unit's remote ouput cable or power antenna trigger cable.
Connect the remote turn on cable to the power terminal labeled as REM.

Disconnect the negative (-) battery cable before mounting or making any connection.
Check the battery and alternator ground (-) connection.
Make sure they are properly connected and free of corrosion.
Before selecting a mounting location for the amplifier, please take cooling and safety into consideration
Avoid areas with excessive vibration & up side down installation!
The amplifiers have been designed with a good heat dissipation heatsink.
In order to avoid excessive heat from the amplifier, it is recommended to find a mounting location
that allows for vertical positioning of the heat sink fins.
