INSTALLATION
BEFORE YOU BEGIN
THE INSTALLATION
Before you install your stereo, read all
the instructions in this owner’s manual. You should be able to answer all of
these questions about your vehicle’s
electrical and sound systems.
• Which of the stereo’s wires is the
power wire?
• Which terminal in my vehicle’s
fuse box is for accessories?
• How do I connect a wire to the
fuse box?
• Which stereo wires are line-level
outputs and which are speaker
outputs?
Also, be aware that installation in your
vehicle might require cutting or m odifying your vehicle.
Preparing the Mounting Area
Before you mount the stereo, make
sure you have all the necessary mat erials. Then confirm that the stereo fits
your vehicle’s mounting area.
Notes:
• This autosound stereo system is a
DIN-E size uni t that requires a 2
inch (57 mm) high by 7
(190 mm) wide by 7
mm) deep mounting area.
• If the mounting area is too large,
you might be able to mount the
stereo with an in-dash installation
kit, available at your local
1
/4-inch (186
1
/2-inch
1
/4-
RadioShack store. Follow the
installation kit’s instructions to
mount the stereo.
Cautions:
• Make sure your vehicle’s mounting area is as level as possible. If
you cannot mount the stereo
exactly level, make sure the stereo will not tilt up more than 30
degrees when it is mounted.
• Be sure to avoid obstructions behind the mounting surface.
Routing Speaker Wires
If you install speakers, avoid routing
the speaker wires near moving parts
or sharp edges. You can usually route
them along the wiring channel beneath the vehicle’s door facings by
carefully removing the molding that
holds the carpet in place. After you
route the speaker wires, replace the
molding.
Removing the Shipping Screw
The shipping screw helps protect the
stereo’s CD player from being damaged during shipment.
Before you mount the stereo, use a
small Phillips screwdriver to remove
the shipping screw from the top of t he
stereo.
If you do not remove the shipping
screw, you cannot remove the supplied sleeve from the stereo and the
CD player will not work.

(illus)
Note: Save the shipping screw in
case you ever want to mail or ship the
stereo. You can secure it to the back
of the stereo with a piece of tape.
MAKING THE
CONNECTIONS
The supplied harness with the 14-pin
connector includes all the lead wires
you need to connect the stereo to
ground, power, some optional components, and speakers.
Important: Do not cut these wires. If
you cut any wire, you cannot obtain a
refund or exchange on this product.
RadioShack will provide warranty service if you cut a wire and find the product is defective.
Cautions:
• For added safety and to protect
your stereo, disconnect the cable
from your vehicle battery’s negative (–) terminal before you begin.
(illus)
• Be sure your speakers can handle
64 watts of power (16 watts per
channel). Each speaker must
have an impedance of at least 4
ohms. Your local RadioShack
store carries a full line of speakers.
• You must connect the GROUND,
+12V TO IGNITION, and +12V TO
BATTERY wires first, then make
all other connections as described
in the following sections before
you plug the harness with the 14pin connector into the stereo. If
you do not make connections in
the order shown, damage to the
stereo is possible if any wire connections are made incorrectly.
You might need additional wire, depending on your individual auto sound
system, to complete the connections.
Your local RadioShack sto re carries a
full line of wire a nd wire mana gement
accessories.
• You m ust connect a separate wire
to each speaker terminal as
described in the following procedure. Do not use a common wire
or chassis ground for an y s peaker
connection.

Using an Adapter Harness
If you are replacing an existing stereo,
or if your vehicle has been factorywired for autosound components, you
might be able t o use an adapter harness to connect the power and speak ers. RadioShack stores sell adapter
harnesses for most vehicles.
Follow the directions that come with
the adapter harness to temporarily
connect the power and speakers.
Connecting Ground, Power,
and Optional Components
Follow these steps to connect the harness with the 14-pin connector to
ground, primary and memory backup
power, and optional components.
(illus - show (Black) Ground

Equipment
1. Disconnect the cable from your
vehicle battery’s negative (
minal.
2. Connect the black ground wire to
a chassis ground, such as a metal
screw attached to a metal pa rt of
the vehicle’s frame. Be sure that
the screw is not insulated from the
chassis by a plastic part.
3. Connect the red power wire (with
in-line fuse holder) to a point in
your vehicle’s fuse block that has
power only when you turn the
vehicle’s key to either the accessory (ACC) or START position.

This connection turns on the stereo when you turn on the ignition
or turn the key to ACC, and turns
off the stereo when you turn off
the ignition. This prevents your
vehicle’s battery from being
drained if you leave the stereo on
when you turn off the ignition.
4. Connect the yellow power/memory wire (with transformer and inline fuse holder) to your vehicle
battery’s positive (+) terminal or to
a point in your vehicle’s fuse block
that provides a continuous source
of 12 volts.
This connection provides power
for the stereo’s components, and
continuous power for the stereo’s
memory when the ignition is
turned off.
5. Connect the blue/white wire to any
optional equipment, designed to
run from a switched source, that
you want the stereo to turn on and
off (such as a booster or a power
antenna).
Connecting an Equali zer/
Booster
If you are connecting the stereo to a
separate equalizer or booster, you
need additional wires (not included).
To increase the total power output
from your system, connect the R
(right) and L (left) line output jacks on
the back of the stereo and blue/white
wire, if necessary, to the equalizer or
booster.

This wire does not provide power
to the components. It s imply turns
them on or off. If you do not use
this wire, secure it with a wire tie
and do not let it touch metal.
Connecting Two Pairs o f
Speakers
If you are using both front and rear
speakers, follow these steps to connect the harness with the 14-pin connector to the speakers.
