3. INSTALLATION

In case you install the OKUR ampliﬁers by yourself, please read owner's manual very carefully. Before you

start your installation, please take all steps into consideration. or, you can have DB Drive or DB Reseach's

authorized dealer to check installation and set your car audio systems.

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 avoid excessive heat from OKUR

circuitry. But for better heat dissipation, 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 a dry and well ventilated location and make sure any cables and drilling car

equipment are not interfere 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 , A7 125.4, A7 300.2 ,A7 750.1 ,A7 1100.1 and A7 1500.1

are designed to use minimum 4 gauge power and ground cables A7 2000.1, A7 2500.1, are designed to

use minimum 0 gauge cables.

Connect the power cables to power terminal labeled as + 12V. A775.4, A7 125.4, A7 300.2, A7 750.1,

A7 1100.1 and A7 1500.1 have built-in fuses. A7 2000.1, and A7 2500.1 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

holders 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.
