Power and Ground Connections
Electrical System Test
The Quadraphonic amplifier is designed to work within a range of 12 volts
to 14.4 volts DC. Before connecting any wiring, use a multi-meter to test
the vehicle’s electrical system for adequate power supply. First, check the
voltage at the battery with the ignition in the off position. The multi-meter
should read no less than 12 volts. Next, check voltage at the battery with
the engine running. The multi meter should show a reading between 12
and 14.4 volts. If your vehicle’s electrical system does not fall within these
parameters, consult an auto electrician before proceeding with the instal-
lation.
The Quadraphonic utilizes a very efficient digital Class D design. For most
installations 8 to 14 gauge power and ground primary wire is suitable. For
longer runs, use thicker gauge wire.
Constant 12 volt(+) Yellow Wire
The constant 12 volt (+) yellow wire should be wired directly to the vehicle’s
positive (+) battery terminal using 8 to 14 gauge primary wire. Start at the
vehicle’s battery, and run the cable back to the amplifier. Avoid running the
wire over engine components and heater cores. The use of the included
in-line fuse is required at the positive (+) battery terminal. Connect the fuse
holder as close to the battery as possible (within 6-8 inches of the positive
(+) battery terminal). This fuse should be no greater than 15 amps. Leave
the fuse out until the final connections have been made.
Ground (-) Black Wire
Locate a metal area as close to the amplifier as possible (preferably the
floor pan or vehicle chassis). Use a wire brush or sandpaper to eliminate
any paint for a better ground connection. Secure the ground wire to the
vehicle using a bolt, star washer and nut. See diagram below for close-up
of correct ground connection.
