WELCOME
Thank you for purchasing a RetroSound®Quadraphonic power
amplier. This full-range Class D digital amplier is the result of
extensive engineering and testing. Its diminutive size enables a wide
variety of installation applications in which space is a premium. The
amplier’s RF shielding allows it to be mounted behind the dash. It has
direct-connect compatibility with all RetroSound®radios, and it may
also be used with any after-market car audio receiver.
Features:
• 45 watts x 4 channels RMS
• Full-range class D digital circuitry
• RF shielding
• Ultra-low current draw
• Advanced protection circuitry
• Built-in high pass crossover
• Direct connection to all RetroSound®radios
The information enclosed in this user’s manual is to be used as a guide to assist you
in the operation and installation of your amplier. This guide does not cover every
installation possibility, every vehicle, or every aspect of the installation process.
Retro Manufacturing, LLC or its subsidiaries assume no responsibility for any installation.

PRECAUTIONS
This owner’s manual provides general installation and operating
instructions. It does not cover every possible installation
application. If you have any reservations about installing the
amplier, contact an authorized RetroSound®dealer, or contact
technical support at [email protected].
IMPORTANT: This amplier is designed for operation in vehicles with 12 volt negative
ground systems only.
PREPARING FOR INSTALLATION
The tools listed below may be required for basic installation:
• Electric drill with bits
• Phillips screwdriver
• Standard screwdriver
• Wire strippers
• Wire crimpers
• Utility knife
• Digital multi-meter

• Turn off all stereo devices before you begin.
• Disconnect the negative (-) battery terminal
from your vehicle’s battery.
NOTE: check your vehicle’s owner’s manual before disconnecting the battery. On
some newer vehicles, disconnecting the battery may require entering an anti-theft
code upon reconnecting the battery and/or may require resetting the vehicle’s
on-board computer. Check with your local dealership if you are uncertain.
• Check for fuel lines, brake lines, oil lines and electrical
cables when planning the installation.
• When choosing a mounting location, make sure there is
adequate clearance around the amplier’s heat sinks
for proper air ow. If you are mounting the amplier
near the radio, never mount it directly to the radio
body, and always maintain at least 2 to 5 inches of
clearance between the amplier and radio body.
• Avoid sharp metal edges when running power
cables. If necessary, use rubber grommets
to protect cables from being frayed.
• Do not install in a place in which the amplier could injure
the driver or passengers if the vehicle suddenly stops.
• Do not mount the amplier upside down. This will
compromise heat dissipation through its heat
sinks and engage its protection circuitry.

Quadraphonic is designed to work within a range of 12 volts to
14.5 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 14.5 volts. If your
vehicle’s electrical system does not fall within these parameters,
consult an auto electrician before proceeding with the installation.
Quadraphonic utilizes a very efcient 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
amplier. Avoid running the wire over engine components and
heater cores. The use of an in-line fuse is recommended. Connect
the fuse holder as close to the battery as possible (within 18-inches
of the battery terminal). This fuse should be no greater than 15
amps. Leave the fuse out until nal connections have been made.
Ground (-) Black Wire
Locate a metal area as close to the amplier as possible
(preferably the oor 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.

MOUNTING THE AMPLIFIER
The compact size of the RetroSound® Quadraphonic amplier
enables considerable installation exibility. For example, the
amplier may be placed behind the dash or under the seats. It is
best to mount the amplier in a location that allows air to freely
circulate around it and allows access to the end panel controls for
adjustments. Although both thermal and overload protection are
built in, if the amplier overheats it will reduce its power output to
maintain operation.
Find a dry, clear and well-ventilated area in which to mount
the amplier. The area should be free of any obstructions that
might block air ow to the amplier. It should be protected
from exposure to direct sunlight. You may use the amplier as a
template to mark the four screw locations with a felt-tip marker. Set
the amplier aside before drilling the mounting holes. Use caution
to make certain there are no objects behind the installation area
that may become damaged by drilling. If mounting beneath a
seat, it is best if there is at least 1 inch of space above the amplier
to permit proper ventilation. If installing the amplier behind the
dash, make sure it has at least two to ve inches of clearance.
