3. Installation
3.1 Installation considerations
If you choose to install the amplifier by yourself, please read the owner’s manual carefully.
Before you start your installation, please take all steps into consideration.
If in doubt, please go to www.b2audio.com for authorized distributors / dealers that will be able to
configure your set up & ensure warranty of your amplifier.
Preparation
Disconnect the negative (-) battery cable before mounting or making any connection.
Check the battery & alternator ground (-) connection. Make sure they are properly connected/dimensioned
& free of corrosion. Before selecting a mounting location for the amplifier, please take cooling & safety
into consideration. Avoid areas with excessive vibration & up side down installation!
Our 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.
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 dual 0 AWG power & ground
terminals. It is crucial that all terminals are used to ensure correct operation.
Connect the power cables to power terminals labeled as +12V.
The
Zero1
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 terminals labeled as GND.
REM ( REMOTE CONNECTION )
Run a remote turn on cable from the sw12V 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.
