Step 3: Wiring The Power
Supply To Vehicle Battery
Use steps below as a draft/template of the general install of
the power supply.
1
Before connecting the power supply, disconnect the vehicle battery
leads to avoid any electrical shocks during installation.
Locate a place where cables are already running through the fi rewall
2
(rear wall of engine bay) to the inside of the cabin.
3
Locate the same fi rewall hole from inside of the vehicle cabin.
Route the power cables of the power supply from the inside of the
4
vehicle cabin out through fi rewall hole.
Note: The cables must be routed inside to outside since the power
supply brick won't fi t through the fi rewall holes. The power supply
brick should remain inside the vehicle cabin.
Connect the positive lead of the power supply (lead with red tape)
5
to the disconnected positive (+) lead of the battery (not the positive
terminal on the battery itself).
Connect the negative lead of the power supply (lead without tape)
6
to the disconnected negative (-) lead of the battery (not the negative
terminal on the battery itself).
7
Connect the positive (+) lead back to the vehicle battery.
8
Connect the negative (-) lead back to the vehicle battery.
NOTE: Having the power supply directly connected to the battery may
drain the battery's life. Please review the vehicle's owner's manual for more
information. Adding a "fuse tap" may be another solution. A "fuse tap" is an
electrical part that functions as a power splitter and is meant to be installed
in the car's fuse box, making the amp shut off when the vehicle's ignition
switch is turned off .
