POWER CONNECTIONS:
CAUTION: ALWAYS DISCONNECT THE VEHICLE
BATTERY’S NEGATIVE (—) TERMINAL BEFORE START-
ING ANY WIRING CONNECTIONS.
Use the diagram below.
To insure a low impedance path from the vehicle's battery to
the 3672, 12-gauge or larger wire should be used to extend
the battery (+) or ground wires.
A 5A inline fuse should be used as close as possible to the
battery's (+) terminal to protect the vehicle and the system.
All audio components should be grounded to a common point
on the chassis. This grounding point must be verified as a true
ground point by checking its continuity with the battery's (-)
terminal, using an ohmmeter. It should also be free of paint
and contaminants.
To Remote-On or Power Antenna
turn-on wire of the Head Unit
NOTE: +12V should be supplied to this terminal
to turn on the 3672. If your Head Unit does not
have a Remote-On Wire, a SPST switch must be
connected between an ignition source and the
3672 Remote-on terminal. Then the 3672 can be
turned on manually by closing this switch.
