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 terminal in my vehicle’s
fuse box supplies power even
when the ignition is turned off?

• Which terminal in my vehicle’s
fuse box is for accessories?

• How do I connect a wire to the
fuse box?

190 ¥ 186 mm) mounting area.

Note:

large, you might be ab le to mount the
stereo with an in-dash installation kit,
available at your local RadioShack
store. Follow the installation kit’s in­structions to mount the stereo.

Cautions:

If the mounting area is too

• 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.

Also, be aware that installation in your
vehicle might require cutting or m odi­fying your vehicle.

Place the stereo as close as poss ible
to the selected mounting location. We
recommend that you install the stereo
by temporarily connecting it to ground
and power, optional com ponents, and
your speakers. Then test t he connec­tions, disconnect the stereo, mount it in
your vehicle, and rec onnect it. Th e in­structions in this manual are arranged
in this order.

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. Thi s au­tosound stereo system is a DIN-E size
unit that requires a 2

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 th e Shipping
Screw

The shipping screw helps protect the
stereo’s CD player from being dam­aged during shipment.

Before you mount the stereo, use a
Phillips screwdriver to remove the
shipping screw from the top of the ste­reo.

(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.
However, your local RadioShack store
will provide warranty
a wire and find the product is defec­tive.

service

if you cut

Cautions:

• For added safety and to protect
your stereo, disconnect the cable
from your vehicle battery’s nega­tive (–) terminal before you begin.

• 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 autosound
system, to complete the connections.
Your local RadioShack sto re carries a
full line of wire a nd wire mana gement
accessories.

• You must 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.

Note: The wires in the wiring harness
have the following colors and labels.

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.

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)

1. Disconnect the cable from your

–

vehicle’s negative (
minal.

) battery ter-

Follow the directions that come with
the adapter harness to temporarily
connect the ground, power, optional
components, and speakers. Then go
to “Connecting the Antenna” on
Page 11.

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.

12-215 4.fm Page 9 Wednesday, Ju ly 14, 1999 3: 34 PM

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 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 (such
as the CD player), and continuous
power for the stereo’s memory
when the ignition is turned off.

Connecting an Equalizer/
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
(right) and L (left) line output jacks on
the back of the stereo and blue/white
wire, if necessary, to the equalizer or
booster.

(illus)

Check the equalizer/booster’s o w ner’s
manual for directions.

R

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).

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 of
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.
