Installation Guide

Identify All Leads

The first step in installation is to identify all the car wires

you'll use when hooking up your sound system.

As you identify each wire, we suggest that you label it

using masking tape and a permanent marker. This will

help avoid confusion when making connections later.

Note: Do not connect the power connector to the stereo

unit until you have made all connections. If there are no

plastic caps on the stereo hooking wires, insulate all

exposed leads with electrical tape until you are ready to

use them. Identify the leads in the following order.

Power Lead

If your car has a radio or is pre-wired for one:

Cut the connector wires one at a time from the plug

(leaving the leads as long as possible) so that you can

work with individual leads.

Turn the ignition on to the accessory position, and

ground one lead of the test bulb to the chassis.

Touch the other lead of the test bulb to each of the

exposed wires from the cut radio connector plug. Touch

one wire at a time until you find the outlet that causes

the test bulb to light.

Now turn the ignition off and then on. If the bulb also

turns off and on, that outlet is the car power lead.

If your car is not wired for an audio unit: Go to the fuse

block and find the fuse port for radio (RADIO), accesso-

ry (ACC), or ignition (IGN).

Battery Lead

If your stereo unit has a yellow lead, you will need to

locate the car's battery lead. Otherwise you may ignore

this procedure. (The yellow battery lead provides contin-

uous power to maintain a clock, memory storage, or

other function.)

If your car has a radio or is pre-wired for one:

With the ignition and headlights off, identify the car bat-

tery lead by grounding one lead of the test bulb to the

chassis and checking the remaining exposed wires from

the cut radio connector plug.

(Continued)

If your car is not wired for an audio unit:

Go to the fuse block and find the fuse port for the bat-

tery, usually marked BAT.

Speakers

Identify the car speaker leads. There are two leads for

each speaker which are usually color coded.

A handy way to identify the speaker leads and the speak-

er they are connected with is to test the leads using a

1.5 V AA battery as follows.

Hold one lead against one pole of the battery and stroke

the other lead across the other pole. You will hear a

scraping sound in one of the speakers if you are holding

a speaker lead.

If not, keep testing different lead combinations until you

have located all the speaker leads. When you label them,

include the speaker location for each.

Antenna

The antenna lead is a thick, black wire with a metal plug

at the end.

Connect All Leads

Now that you have identified all the wires in the car, you

are ready to begin connecting them to the stereo unit

wires. The wiring diagram (

page 25) shows the prop-

er connections and color coding of the leads.

We strongly recommend that you test the unit before

making a final installation.

You can set the unit on the floor and make temporary

connections to test the unit. Use electrical tape to cover

all exposed wires.

Important: Connect the red power lead last, after

you have made and insulated all other connections.

Ground

Connect the black ground lead of the power connector

to the metal car chassis.

Speakers

Connect the speaker wires. See the wiring diagram

( page 25) for the proper hookups. Follow the diagram

carefully to avoid damaging the speakers and the stereo

unit.

The speakers used must be able to handle more than 45

W of audio power. If using an optional audio amplifier,

the speakers should be able to handle the maximum

amplifier output power. Speakers with low input ratings

can be damaged. Speaker impedance should measure

4–8

, which is typically marked on most speakers.

Lower or higher impedance speakers will affect output

and can cause both speaker and stereo unit damage.

Battery

Connect the yellow battery lead to the correct radio wire

or to the battery fuse port on the fuse block.

Antenna

Connect the antenna by plugging the antenna lead into

the antenna receptacle.

Equipment

Connect any optional equipment such as an amplifier,

according to the instructions furnished with the equip-

ment. Leave about 12" (30 cm) of distance between the

speaker leads/amplifier unit and the antenna/antenna

extension cord. Read the operating and installation

instructions of any equipment you will connect to this

unit.

Power

Connect the red power lead to the correct car radio wire

or to the appropriate fuse port on the fuse block.

If the stereo unit functions properly with all these con-

nections made, disconnect the wires and proceed to the

final installation.

Final Installation

Lead Connections

Connect all wires, making sure that each connection is

insulated and secure. Bundle all loose wires and fasten

them with tape so they will not fall down later. Now

insert the stereo unit into the mounting collar.

Congratulations! After making a few final checks, you're

ready to enjoy your new auto stereo system.

Final Checks

1. Make sure that all wires are properly connected and

insulated.

2. Make sure that the stereo unit is securely held in the

mounting collar.

3. Turn on the ignition to check the unit for proper

operation.

If you have difficulties, consult your nearest author-

ized professional installer for assistance.

Preparation

• We strongly recommend that you wear gloves for

installation work to protect yourself from injuries.

• When bending the mounting tabs of the mounting

collar with a screwdriver, be careful not to injure

your hands and fingers.

• Disconnect the cable from the negative

battery ter-

minal (see cautions below).

• Unit should be installed in a horizontal position with

the front end up at a convenient angle, but not more

than 30˚.

Less than 30˚

Caution: Do not disconnect the battery terminals of

a car with a trip or navigational computer since all

user settings stored in memorywill be lost. Instead

take extra care with installing the unit to prevent

shorts.
