4. INSTALLATION
If you choose to install the
M12
series by yourself, please read the owner's manual carefully.
Before you start your installation, please take all steps into consideration. Otherwise, please go to

4-1. MOUNTING PREPARATION
Disconnect the negative ( ) battery cable before mounting
B2
series 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
for the amplifier, please take cooling and safety into consideration.
B2
amplifiers have been designed with a good heat radiation heatsink to avoid excessive heat
from the amplifier circuitry. For optimum heat radiation performance, it is recommended to
find a mounting location that allows for vertical installation of the heat sink fins.
