PRECAUTIONS
This owner’s manual provides only general installation and
operating instructions. It does not cover every possible installation
application. If you have any reservations about installing the
amplier, contact an authorized RetroSound®dealer, or contact
technical support at [email protected].
IMPORTANT: This amplier 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

5
• 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 amplier’s heatsink
for proper air ow. If you are mounting the amplier
near the radio, never mount it directly to the radio
body, and always maintain at least 2 to 5 inches of
clearance between the amplier 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 amplier could injure
the driver or passengers if the vehicle suddenly stops.
• Do not mount the amplier on its side or upside down.
This will compromise heat dissipation through the heatsink
and engage its protection circuitry. This can also damage
the amplier. Any damage caused by improperly
mounting the amplier will void your warranty.

Technophonic 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 positive (+) battery terminal with the ignition in the off
position. The multi-meter should read no less than 12 volts. Next, check
voltage at the positive (+) battery terminal 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 installation.
Technophonic utilizes a very efcient digital Class D design. For most
installations 8 to 10 gauge power and ground primary wire (not included)
are suitable. For longer runs, use thicker wire (Example: For installation
beneath the front seat, use 10 gauge wire. For installation in the trunk,
use 8 gauge wire) .
Battery (+) Wire (Constant 12 volt)
A constant 12 volt Battery (+) Wire (not included) should be wired directly
to the vehicle’s positive (+) battery terminal using 8 to 10 gauge primary
wire. Start at the vehicle’s positive (+) battery terminal, and run the wire
back to the Battery (+) terminal on the side panel of the amplier. Avoid
running the wire over engine components and heater cores. The use
of an in-line fuse (not included) 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
60 amps. Leave the fuse out until nal connections have been made.
Ground (-) Wire
Locate a metal area as close to the amplier 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 (not
included) to the vehicle using a bolt, star washer and nut (not included).
See diagram below for close-up of correct ground connection (connect
the other end to the amplier’s Ground terminal).

MOUNTING THE AMPLIFIER
It is best to mount the amplier 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 amplier overheats it will reduce its power output to
maintain operation.
Find a dry, clear and well-ventilated area in which to mount
the amplier. The area should be free of any obstructions that
might block air ow to the amplier. It should be protected from
exposure to direct sunlight.
You may use the amplier as a template to mark the four screw
locations with a felt-tip marker. Set the amplier aside before drilling
the mounting pilot holes. Use caution to make certain there are no
objects behind the installation area that may become damaged by
drilling. Make sure the amplier has at least two inches of clearance
above the heatsink to allow for heat dissipation.

NOTE: The fuses included with the amplier only protect the amplier itself. Installing a fuse
near the battery is required to protect your vehicle and wiring in case of a short-circuit.
Check the fuses on the bottom of the amplier for troubleshooting (30 amp ATC style).
CAUTION: It is very important that you use the same gauge wire for both the Battery (+)
(12 volt constant) and the ground.
