DB Drive A72500.1 - Manual (Page 5)

3-1. MOUNTING PREPARATION
Disconnect the negative ( ) battery cable before mounting your OKUR 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 take some concerns into consideration with cooling efficiency and safety.
3-2. MOUNTING PREPARATION
The OKUR amplifier uses a specially designed heat radiation heatsink to avoiding excessive heat from
OKUR circuitry.
But for better heat disipitation, It is good to find the mounting location where you can install
OKUR vertically with the heatsink fins and better air flow around heat sink.
For the safety, you have to find dry and well ventilated location and make sure any cables
and drilling car equipment are not interfaced with mounting location.
Be sure the mounting 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
12V ( POWER CONNECTION )
Before mounting Platinum series, disconnect the negative ( ) wire from battery to protect
any accidentIal damage to amplifier and audio system.
A775.4 , A7125.4, A7300.2 ,A7750.1 ,A71100.1 and A71500.1 are designed to use minimum 4 gauge power
and ground cables A72000.1, A72500.1, are designed to use minimum 0 gauge cables.
Connect the power cables to power terminal labeled as + 12V.
A775.4 , A7125.4, A7300.2, A7750.1 ,A71100.1 and A71500.1 have built-in fuses.
A72000.1, and A72500.1 are not euipped with fuses so you need to install external
fuses.
In order to install external fuses, connect one end of fuse holder to the power cable and the other end
of fuse holder to positive battery within 18in of 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
GND ( GROUND CONNECTION )
Locate a secure grounding connection as close to platinum 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 head units remote switched + 12V output.
