FEATURES

RadioShack is a registered trademark used by Tandy Corporation.

Your RadioShack High-Power In-Dash

AM/FM Stereo Cassette has many practi-

cal, easy-to-use features, and you can in-

stall it in almost any vehicle. The tuner’s

digital synthesized PLL (Phase-Locked

Loop) circuitry gives you precise tuning

and drift-free reception. The stereo’s anti-

theft control panel is easy to remove.

The auto-reverse cassette deck, memo-

ry tuning, and seek and scan tuning fea-

tures all help make your stereo’s

operation simple and quick to he lp you

drive safely.

Caution:

Use common sense. Do not

change your stereo’s settings in heavy

traffic or during hazardous driving condi-

tions.

This stereo’s features include:

quickly remove and store the stereo’s

control panel in the supplied carrying

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 these

questions about your vehicle’s electrical

system:

• Which terminal in the vehicle’s fuse

box supplies power even when the

ignition is off?

• Which terminal in the vehicle’s fuse

box is for accessories?

• How do I connect a wire to the fuse

box?

Also, be aware that installation in your

vehicle might require cutting or modifying

your vehicle.

Place the stereo as close as possible to

the selected mounting location. We rec-

ommend that you install the stereo by

temporarily connecting it to ground and

power, optional components, and your

speakers. Then test the connections,

disconnect the stereo, mount it in your

vehicle, and reconnect it. The instruc-

tions in this manual are arranged in this

order.

Cautions:

• For added safety and to protect your

stereo, disconnect the cable from

your vehicle’s negative (–) battery

terminal before you begin .

• Be sure your speakers can handle

20 watts of power output per chan-

nel. Each speaker must have an

impedance of at least 4 ohms. Your

local RadioShack store carries a full

line of speakers.

Preparing the Mounting Area

Before you mount the stereo, make sure

you have all the necessary materials.

Then confirm that the stereo f its your ve-

hicle’s mounting area. This stereo is a

DIN-E size unit that requires a 2

-inch

high by 7

-inch wide by 6

-inch

deep (53

182

170 mm) mounting ar-

ea.

Caution:

Be sure to avoid obstructions

behind the mounting surface.

Note:

If the mounting area is larger than

the stereo requires, you might be able to

mount the stereo with an in-dash installa-

tion kit, available at your local Ra-

dioShack store. Follow the installation

kit’s instructions to mount the stereo.

Routing Speaker Wires

If you install speakers, avoid routing the

speaker wires near moving parts or sharp

edges. You can usually route wires along

the wiring channel beneath the vehicle’s

door facings by carefully removing the

molding that holds the carpet in place. Af-

ter you route the wires, replace the mold-

ing.

12-2115a.fm Page 5 Wednesday, January 12, 2000 11:18 AM

Using an Adapter Harness

If you are replacing an existing stereo, or if your vehicle has been factory-wired

for autosound components, you can use an adapter harness to connect the power

and speakers. RadioShack stores sell adapter harnesses for most vehicles.

Follow the directions that come with the adapter harness to temporarily connect the

power and speakers.

After you connect the adapter harness to your vehicle, you can skip to “Testing the

Connections” on Page 11.

The supplied wiring harness with its 14-

pin connector includes all the lead wires

you need to connect the stereo to

ground, power, some optional compo-

nents, and speakers.

Important:

Do not cut these wires. If

you cut any wire, you cannot obtain a re-

fund or exchange on this product. Ra-

dioShack will provide warranty service if

you cut a wire and find the product is de-

fective.

You might need additional wire to com-

plete the connections, depending on

your individual auto sound system. Your

local RadioShack store carries a full line

of wire and wire management accesso-

ries.

Cautions:

•You

must

connect the GROUND,

+12V TO IGNITION, and +12V TO

BATTERY wires first, then make all other

connections as described in the fol-

lowing sections before you plug the

wiring harness into the stereo. If you

do not make the connections in the

order shown, an incorrect connection

could damage the stereo.

•You must connect a separate wire to

each speaker terminal as described

in “Connecting Two Pairs of Speak-

ers” on Page 9 or “Connecting One

Pair of Speakers” on Page 10. Do

not use a common wire or chassis

ground for any speaker connection.

Connecting Ground, Power, and Optional Components

Follow these steps to connect the wiring harness to ground, power, clock memory,

and optional components.

Wires

14-Pin

Connector

1.Disconnect the cable from your

vehicle’s negative (

–) battery termi-

nal.

2.Connect the black ground wire to a

chassis ground, such as a metal

screw attached to a metal part of

the vehicle’s frame. Be sure the

screw is not insulated from the

chassis by a plastic or rubber part.

Connect the red +12V To Ignition wire

(with in-line fuse holder) to a point in

your vehicle’s fuse block that has

power only when you turn the vehi-

cle’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 igni-

tion.

4.Connect the yellow +12V To Battery

wire (with in-line fuse holder) to your

vehicle’s positive (+) battery termi-

nal or to a point in your vehicle’s

fuse block that provides a continu-

ous source of 12 volts. This connec-

tion provides power for the stereo’s

components (such as the clock),

and continuous power for the ste-

reo’s memory when the ignition is

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 remote amplifier or a

power antenna).

This wire does not provide power to

the components. It simply 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.

Note:

To connect an optional amplifier.,

use the line out connectors on the back

of your car stereo and follow the instruc-

tions in the amplifier’s owner’s manual.

Connecting Two Pairs of Speakers

If you are using both front and rear speaker s, f ollo w these st eps t o co nne ct the wirin g

harness to the speakers.

1. Connect the gray wire to the right front speaker’s positive terminal. This terminal

is usually marked with a plus (+) sign or red mark.

2. Connect the gray/black wire to the right front speaker’s negative terminal. This

terminal might be marked with a minus (

–) sign or it might not be marked at all.

3. Connect the white wire to the left front speaker’s positive terminal.

4. Connect the white/black wire to the left front speaker’s negative terminal.

5. Connect the violet wire to the right rear speaker’s positive terminal.

6. Connect the violet/black wire to the right rear speaker’s negative terminal.

7. Connect the green wire to the left rear speaker’s positive terminal.

8. Connect the green/black wire to the left rear speaker’s negative terminal.
