Installation

Preparation

CAUTION: Improper installation can damage your stereo and other components in your vehicle's autosound system.

Before you install your stereo, read all the instruction's in this owner's manual. You should be able to answer all of these questions about your vehicle's electrical and sound systems:

Does my vehicle have a 12-voltnegative ground electrical system?

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?

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 recommend that you install the stereo by temporarily connecting it to ground and power, optional components, and your speakers. Then test the connections. Next, disconnect the stereo, mount it in your vehicle, and then reconnect it. The instructions in this manual are arranged in this order.

CAUTION: Be sure your speaker can handle 32 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.

Setting the Shaft Spacing

The size of existing openings in the dash or installation kit determines the best spacing between the stereo's shafts (knobs).

The space between the shafts is preset to 5-13/16inches (148 mm) at the factory. You can change the spacing to5-5/8inches (142 mm), to5-3/8inches (136 mm), or to5-1/8inches (130 mm).

Follow these steps if you need to change the shaft spacing.

1.Loosen each shaft nut about halfway up the shaft.

2.Move each shaft positioner to the correct pair of holes.

3.Hold each shaft positioner in place as you re-tightenits shaft nut. Preparing the Mounting Area

Before you mount the stereo, make sure you have all the necessary materials. Then confirm that the stereo fits your vehicle's mounting area.

Note: If the mounting area is too large, you might be able to mount the stereo with the supplied gasket or an in-dashinstallation kit, available at your local RadioShack 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 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.

Making The Connections

The supplied harness with the 14-pinconnector includes all the lead wires you need to connect the stereo to ground, power, optional components, and speakers.

IMPORTANT: Do not cut the lead wires. If you cut any wire, you cannot obtain a refund or exchange on this product. However, your local RadioShack store will provide warranty service if you cut a wire and find the product is defective.

You might need additional wire, depending on your individual autosound system, to complete the connections. Your local RadioShack store carries a full line of wire and wire management accessories.

CAUTIONS: For added safety and to protect your stereo, disconnect the cable from your vehicle battery's negative (-)terminal before you begin.

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 wire harness with

the 14-pinconnector into the stereo. If any wire connections are made incorrectly or out of order, damage to the stereo is possible.

Note: The wires in the wire harness have these colors and labels.

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 any speaker connection.

Using an Adapter Harness

If you are replacing an existing stereo, or if your vehicle has been factory-wiredfor autosound components, you might be able to 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.

Connecting Ground, Power, and Optional Components

Follow these steps to connect the wire harness to ground, primary and memory backup power, and optional components.

Note: The (Red +12V to Ignition) and (Yellow +12V to Battery) wires each have an In-Linefuse Holder.

1.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 that the screw is not insulated from the frame by a plastic part.

2.Connect the red +12V to IGNITION wire (with in-linefuse 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.

3.Connect the yellow +12V to BATTERY wire (with in-linefuse holder) to your vehicle battery's positive (+) terminal or to a fuse that provides a continuous source of 12 volts.

This connection provides power for the stereo's components (such as the clock), and continuous power for the stereo's memory when the ignition is turned off.

4.Connect the blue/white AMP REMOTE TURN ON 500MA MAX 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 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: The optional equipment must be designed for use with a switched power lead.

Connecting Two Pairs of Speakers

If you are using both front and rear speakers, follow these steps to connect the harness to the speakers.

or it might not be marked at all.

4.Connect the white FRONT LEFT (+) wire to the left speaker's positive terminal.

5.Connect the green/black REAR LEFT (-)wire to the left speaker's negative terminal.

Connecting the Antenna

Connect the vehicle's antenna cable to the stereo's large black antenna connector.

Testing the Connections

Make sure you have securely made all other connections, then plug the harness's connector into the stereo's 14-pinwiring socket.

Then reconnect the cable to the vehicle battery's negative terminal to test the connections.

Turn on your vehicle's ignition. The display should light and the currently set time (or 12:00) should appear on the display when you turn the left inner shaft clockwise until you hear it click to turn on the stereo.

CAUTION: If the stereo does not work, immediately disconnect the cable from your vehicle battery's negative (-)terminal. Then recheck your connections.

After you verify that the display lights and the clock appears, follow the instructions in "Mounting the Stereo" below.

Mounting The Stereo

Be sure you test the stereo first and verify that it works properly. (See "Making the Connections" above.) Then follow these steps to mount the stereo.

1.Disconnect the cable from the vehicle battery's negative (-)terminal.

2.Disconnect the wire harness and the antenna.

Note: If you are using an in-dashinstallation kit, follow the procedure outlined in the kit, and proceed to Step 4 (skip Step 3).

3.Position the stereo in the dashboard as follows:

a.Place one supplied nut and washer on each shaft and tighten the nuts about halfway up the shafts.

b.From behind the mounting surface, insert the shafts through the mounting surface.

c.Adjust the nuts on the shafts until the stereo's front panel lines up properly with the dashboard. Insert the supplied gasket if additional front panel support is needed.

d.Place another supplied nut and washer on each shaft and tighten the nuts to secure the stereo against the dashboard.

4.Place the trim plate and shaft-spacingadapters over the shafts. Select theshaft-spacingadapters that fit over the shafts and into the cutouts in the trim plate.

5.Place the remaining washers and nuts on the shafts and tighten the nuts against the shaft-spacingadapters.

Note: To further secure the stereo, if your vehicle's dashboard space permits access to the back of your stereo, attach one end of the metal strap to the bolt on the back of the stereo. Then attach the other end of the strap to a solid metal part of the vehicle using an existing bolt or the supplied self-tapingscrew. This strap also ensures that the stereo is properly grounded.

6.Place the inner and outer knobs on the shafts.

7.Reconnect the wire harness and antenna.

8.Reconnect your vehicle's negative (-)battery cable.

Using The Line Level Components

This stereo has preamp outputs (phono connectors) for low-noiseconnection to an optional equalizer/booster, power amplifier, or other device that hasline-levelinputs.

To ensure a low-noiseconnection, connect a ground wire between the stereo and any additional component.

Note: When connecting an equalizer/booster not sold by RadioShack, refer

to its owner's manual.

Connecting a Compact Disc Player

You can connect a portable CD player (or other audio component with a line-leveloutput) to the stereo.

Use a stereo mini-jackcable with1/8-inchplugs. (Your local RadioShack store offers a wide variety ofmini-jackcables.)

Connect the cable to CD IN and to the output jack of the CD player or other component.

Note: When you plug a cable into CD IN, you will not be able to listen to the radio or a cassette tape. Be sure you disconnect the CD player when you are not using it.
