PRECAUTIONS
PLEASE OBSERVE THESE PRECAUTIONS WHEN INSTALLING
AND USING THIS UNIT:
This user’s manual does not cover all possible installation scenarios.
If you feel you can’t install this unit yourself, take it to a local car
audio professional. If you have questions about installing your
radio, contact us at [email protected]
or by calling 888.325.1555.
• Do not disassemble or modify the unit or attempt to
repair the unit yourself. If the unit needs to be repaired,
consult your dealer or Retro Manufacturing, LLC.
• Do not use the unit when it is out of order. If the unit is out of
order or is in an abnormal state (has foreign objects in it, is
exposed to water, smokes or smells), turn it off immediately
and consult your dealer or Retro Manufacturing, LLC.
• Refer fuse replacement to qualied service personnel.
When the fuse fails, eliminate the cause and have it
replaced by a qualied service technician with the fuse
prescribed for this unit. Incorrect replacement of the fuse
may lead to smoke, re and damage to the unit.
• If the unit does not turn on, check the connections rst.
Then check the fuse in your vehicle’s fuse panel and the
fuse at the unit’s wiring harness. Do not expose the unit to
direct sunlight or excessive heat. Excessive heat will raise the
interior temperature of the unit, which may damage it.
• Do not use the unit where it is exposed to moisture or
dust. Exposure of the unit to moisture or dust may lead
to smoke, re or other damage to the unit and will void
your warranty. Make sure the unit does not get wet
in car washes or on rainy days. Exposure to moisture
will damage the unit and void your warranty.

PRECAUTIONS
• Refer wiring and installation to qualied service personnel.
Installation of this unit requires special skills and experience.
Retro Manufacturing, LLC is not liable for any problems resulting
from improper installation of the unit. Please be sure to follow
the instructions carefully while attempting installation.
• Follow the instructions to wire the unit. Failure to follow the
instructions could cause damage to the unit, re, injury or death.
• Be careful not to damage the leads. Prevent them from
being caught in the vehicle chassis or from being damaged
by screws or moving parts such as seat rails. Do not scratch,
pull, bend or twist the leads. Do not install them near heat
sources or place heavy objects on them. If the wiring must
be routed around sharp metal edges, protect them by
wrapping them with vinyl tape or similar protections.
NOTE: Cutting the main wiring harness, antenna lead,
USB or auxiliary cables will void the warranty of your radio.
• We recommend only using the designated parts and
tools when installing this unit. If mounting the radio face
or body remotely, use extreme caution not to damage
internal parts when choosing brackets and screws.
• Do not interfere with safety-related vehicle components.
Do not wire or afx this unit to the fuel tank, brakes,
suspension, steering wheel, pedals, etc. Check for electric
wiring, piping and other items before installing the unit.
• Never install the unit in a location where it
interferes with your eld of vision.
• Use the supplied metal backstrap to secure the rear
of the unit. Failure to secure the back of the unit will
damage the shafts and void your warranty.

7
PRECAUTIONS
• Never splice into the power lead to supply
other equipment with power.
• After installation and wiring, always check the normal
operation of other electrical equipment.
• Make sure that no wires interfere with driving
or getting in and out of the vehicle.
• Insulate all exposed wires to prevent short-circuiting or electric shock.
• Do not operate the unit for prolonged periods
with the engine off. Prolonged operation with the
engine turned off will drain the battery.
• Keep the volume of your radio at a level that allows
you to hear outside noises such as emergency sirens
and train crossing warnings. Prolonged exposure to
high volume levels may also result in hearing loss.
• This unit requires 12 volts to both the red and yellow power leads.
The unit will not work without 12 volts to both of these leads.
• Always disconnect the negative (-) battery cable before
beginning installation. Verify the battery ground by checking
that one wire is connected to the vehicle’s starter mounting
bolt or engine block and the other to the vehicle’s chassis using
at least 8 gauge wire. Make sure the alternator or generator
connections are secure and free from corrosion, rust or dirt.
• This unit is designed for operation with a negative ground
12 volt DC battery system. Do not operate this unit with
other battery systems, especially an 18 or 24 volt DC or a
positive ground system. If you have a 6 volt system, you
need to either convert to 12 volt DC or purchase a separate
inverter that would increase the voltage to 12 volts.
NOTE: The inverter needs to be rated at 10 amps or higher
in order for the radio to operate properly.

STEP 1: Install the Radio Face
Plug the ribbon cable included with the Motor 4 radio body
into the radio face. After plugging in the radio face, attach
it to the radio body (if it is not already attached) and tighten
with the four radio face mounting screws provided in the
radio face box (the screws are very small and are included
in the hardware kit included with your Motor 4 box).
The RetroSound®logo on the Motor 4 radio body should be facing
upwards. Take care to not install the face to the body upside down.
NOTE: Optionally, the radio face can be mounted remotely up to nine feet away
from the Motor 4 radio body using an optional Face to Body Extension Cable (sold
separately). In some installation applications, a bracket (not included) can be used
to mount the radio face to the radio body at an angle.

INSTALLATION INSTRUCTIONS
STEP 2: Install InfiniMount Brackets
Attach each InniMount bracket to the correct side of the radio
body using the supplied screws (the brackets are marked with
a “L” for left and a “R” for right). Before tightening the screws,
you need to adjust the brackets up, down, forward or backward
(see Figure 2). You may also rotate, cut, or bend the brackets to
achieve the perfect t. Complete the assembly with at least two
screws tightened on each side.*
*In some installations the brackets must be moved far enough forward or backwards
or rotated so that only two screws will align with the threaded screw holes
on the radio. Two screws are sufcient to hold the brackets in place.
NOTE: You may need to cut, trim or bend the brackets to achieve a perfect t. You
can even drill new mounting holes into the bracket if you need to. The InniMount
system is designed to be modied. Modifying your brackets will NOT void your warranty.

STEP 3: Mount Shafts to Brackets
To match the the location of your shafts to the proper width of your
vehicle’s dash, measure the distance between your existing shaft
holes from center to center.
Mount a shaft to each bracket using the supplied shaft nuts
and washers. Finger tighten the shaft nuts to prepare for the nal
installation (see Figure 3). Once you ensure the proper width, snug
down the screws and nuts (DO NOT OVERTIGHTEN).
DO NOT OVERTIGHTEN. OVERTIGHTENING THE SHAFT NUTS WILL DAMAGE THE SHAFTS.
DAMAGE FROM OVERTIGHTENING WILL VOID YOUR WARRANTY.
