4-2. MOUNTING PREPARATION
Digital-series amplifiers use heavy-duty and good heat radiation heatsink design for
avoiding excessive heat from amplifier circuitry. But for better heat radiation performance,
It is good to find the mounting location where you can install Digital-series Amplifiers vertically
with the heatsink fins and better air flow around Digital-series amplifiers.
For the safety, you have to find dry and well ventilated location and make sure any cables
and car equipment are not interfaced with mounting location.
Be sure the mounting location and drilling of pilot cables for mounting will not present
a hazard to any cables, control cables, fuel lines, Fuel tanks,hydraulic lines or other vehicle
systems or components.
4-3. +12V, GND, REM CONNECTION
Before mounting Digital-series amplifiers, disconnect the negative ( ) wire from battery to
protect any accidentIal damage to amplifier and audio system.
Digital-series are designed to use 0 gauge power and Ground connection.
Connect the power cables to power terminal labeled as + 12V
Digital-series are not equipped with Fuses so you have to install the external fuses on
the power cable for Digital-series.
Connect one end of fuse holder to the power cable and the other end of fuse holder
to positive battery 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.
Be sure to use fuses and fuse holder adequate for the application
GND ( GROUND CONNECTION )
Locate a secure grounding connection as close to amplifier 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 size 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 sw 12V source.
You will be using to turn on the system components.
This may be a toggle switch, a relay, or your source unit's remote trigger cables, or power
antenna trigger cable.
Connect the remote turn on cable to the power terminal labeled as REM.
