General Installation
Thank you for your purchase of this Custom Autosound product!
Owner- Installer: Please review installation instructions and owners manual.
Keep in mind that your radio and/or speakers are custom equipment designed specifi-
cally for your year vehicle. It should be handled carefully and installed preferably by an
auto radio specialist. We suggest that you “Bench Test” the unit before installation, as
we do, prior to shipment.This is to insure that the equipment functions properly before
the time is spent on installation. This way, if a careless installation occurs and the unit
becomes "fried" or some other possible damage, the installer is responsible. Shipping
damage does occasionally occur. If you should suspect shipping damage, please con-
tact the delivery company at once.
Please read the owners manual thoroughly before using your radio.
It is recommended that you disconnect the negative lead from the battery before
installing any electronic equipment in your vehicle. Reconnect when wiring is complete.
First, you will need to remove the knobs of your current radio, bezels and shaft nuts.
Unplug the main wire harness and speaker leads from the back of the radio. Disconnect
antenna lead and remove mounting strap from the back of the radio. The radio is now
ready to be removed from the dash. Check the original radio for signs of water or oil
damage from leaks. If leaks are present, do not install the new radio. Water, oil or any
other liquid damage is not covered under the new radio warranty.
REAR MOUNTING STRAP OMISSION VOIDS WARRANTY!
Attach the rear mounting strap to rear of radio. Install the radio from behind the dash.
Now attach the mounting strap to the dash or firewall using an existing bolt or screw.
Now install any outer custom trim bezel, if one was furnished for this application and
attach shaft nuts to secure the radio in the dash. Once the radio is centered and
secured, you can install the knobs.
Please refer to wiring instructions on page 4&5.
Plug in antenna lead On speaker hook up make sure the positive lead goes to the posi-
tive terminal and the negative lead to the negative terminal of the speakers. A minimum
of two (or one dual) speakers is required for this stereo radio. DO NOT CONNECT
ANY TWO SPEAKER LEADS TO EACH OTHER OR TO VEHICLE GROUND. Radio
damage will occur. If less than four speakers are used, tape off remaining speaker
leads to prevent a short.
Plug in or wire the red power wire to a switched 12volt source. Plug in or wire the
orange memory wire to a constant 12volt source. Wire the black ground wire to a clean,
solid chassis point or original ground wire from the factory radio.
Good Listening! Audio quality is only as good as speaker quality!

Antenna Noise
A static or crackle heard through the speakers, usually when the car is running, but
sometimes present with the ignition off. If a crackling static if present, follow the steps
outlined below to confirm the antenna as the source of the noise.
1. Start the car engine.
2. Switch on the USA-630.
3. Adjust the volume so that noise is audible.
4. Reduce volume setting of the car stereo but do not switch it off. If noise decreas. .
es or disappears, the signal is most likely being picked up by the car antenna. If . .
the noise persists after following the steps listed below, proceed to ignition Noise.
Elimination
1. Test or have tested the antenna lead for any breaks or shorts. Signs of crimping, . .
kinking fraying or rust usually indicates damage to the cable. Replace the
antenna or cable if necessary.
Ignition Noise
A popping or crackling noise heard through the speakers. The noise will vary as the
engine rpm varies. The noise will Only be present with the engine running
Elimination
1. Install an L.C. Filter Network in the power lead of the USA-630. The filter should be .
rated at a minimum of 3 amps.
2. Inspect spark plug and distributor cable for signs of wear or damage. Replace as .
necessary using resistor cable only. Metal conductor ignition cables increase
. static interference.
NOTE: Do not use spark plug or distributor noise filters as these can create more prob-
lems than they can solve. They decrease the quality of the spark generated by the
spark plugs and they may create more static than they eliminate.
Electrical Noise
A popping heard when the lights, turn indicators, windshield wipers, cigarette lighter,
etc. are switched on indicate a vehicle wiring deficiency. Most occurrences are minor
and preset no risk to the stereo system other than the annoyance to the listener.
However, severe cases may damage the speakers, minor occurrences can be reme-
died. A professional must attend to severe occurrences, as they present a threat to not
only the stereo system but to the vehicle wiring itself.
Elimination
1. Install an L.C. Filter Network in the power leads of the USA-630. The filter should
be rated at a minimum of 3 amps.
2. If the noise persists, consult a professional automotive service technician.
Power and Speaker Connections (Refer to Wiring Diagram on page 5.)
A-Main Power-Red Wire B+
Connect the RED wire (B+) to an accessory fuse that is switched OFF when
the key switch is in the OFF position and is switched ON when the key switch
is switched to the ON or accessory position. (This does not apply to cars
with 6volt system)
B-Memory Back-Up-Orange Wire B+
Connect the orange wire (memory B+) to an accessory fuse that is always
ON regardless of the position of the key switch.The lead supplies power to the
program memory and the clock circuit when the USA-630 is switched off.(This
does not apply to cars with 6volt system)
C-Power Antenna (Auto-Antenna) - Yellow Wire
This wire can be connected to the positive switch terminal of the relay for the
auto antenna (if your car is equipped )or to the remote on switch of the ampli-
fier or booster (if equipped). NOTE:DO NOT connect this wire to a negative
position or to any device that requires high current Otherwise the radio may
fail or become "fried". If your car is not equipped with an auto antenna,leave
this wire sealed and do not allow it to short to any other positions.
D - Ground Wire - Black
Connect the black ground wire to any clean paint and contaminant free area
of vehicle chassis.
NOTE: Proper grounding is essential for optimum performance of your radio.
E - Speaker Wires
Connect the speaker wires as shown in Figure 1.
Low Level Output (Line Out Jacks) Connection
The USA-630 is equipped with low level, high impedance outputs. The low
level outputs (RCA type Line Out Jack) will not drive speakers. If you are con-
necting an amplifier or plan on it in the future, it is recommended to use these
leads. It makes for a cleaner and easier Installation.

Noise Suppression
All CAM Systems are designed for maximum electrical noise rejection. In some instal-
lations however, electrical noise may affect the quality of sound reproduction.
If noise is present after installing the USA-630, identify the source of the noise using
the descriptions under Sources Of Electrical Noise. To eliminate the noise follow the
procedures described under Elimination of the specific noise source.
Noise Suppression
1-Check all ground connections. Remove paint from painted surfaces to secure a
. good electrical ground.
2-Check battery posts. If contacts are corroded or loose, clean and tighten both
. terminals.
3-Check battery or add fluid.
4-Check condition of spark plug and distributor leads. Worn or damaged leads will
. generate noise than can be very difficult to eliminate.
5-Check installation of factory noise suppressor(s). Verify that the connections are . .
. solid. Refer to the vehicles service manual for nose suppressor location or allow a .
. qualified mechanic to inspect the device(s) for you.
6-(Optional) Some professional installers will install a simple L.C. noise filter even if . .
. there is no noise present in the system. This is a simple and relatively inexpensive .
. device available at your nearest Autosound dealer or electronic supply store. Most .
. filters designed for car stereos carry a current rating of 3 amps or more. Follow the .
. manufacturers installation instructions. This filter is installed in the power lines of the
. car stereo.
Sources Of Electrical Noise
Alternator Noise
This noise is generally a high pitch whine present with the engine running.The pitch of
the whine will vary as engine RPM varies. Alternator noise usually becomes more
apparent with an electrical load to the system. Switching the headlights on usually
increases the noise.
Elimination
1. Install an L.C.noise filter (available from your Autosound dealer or your nearby .
electronic or automotive supply store) in the power lines of your USA-630. This filter . .
should be rated at 3 amps minimum.
2. Start the car’ s engine.switch on the lights (to accentuate the noise) and switch . .
on the USA-630. If noise is still present, proceed to step 3.
3. Install an alternator noise filter (available from your Autosound dealer or your . . .
nearby electronic or automotive supply store). Follow manufacturer’ s installation .
. instructions.
