(120-2157) Installation Faxback Doc. # 58422
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 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 connection 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 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
materials. Then confirm that the stereo fits your vehicle's mounting area.
This auto sound stereo system is a DIN-E size stereo that requires a
2-1/16 inch high by 7-1/8 inch wide by 5-15/16 inch deep (52 x 181 x 152
mm) mounting area.
Note: 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
RadioShack store. Follow the installation kit's instructions to
mount the stereo.
CAUTIONS: 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 from being damaged during
shipment.
Before you mount the stereo, use a Phillips screwdriver to remove the
shipping screw, spacer, and rubber washer from the top of the stereo.
Note: Save the screw, spacer, and washer in case you need to mail or ship
the stereo. Secure them 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 Radio
Shack store will provide warranty service if you cut a wire and
find that the product is defective.
You might need additional wire, depending on your 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.
Be sure your speakers can handle 92 watts of power (23 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 14-pin 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 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-wired for auto sound 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 ground, power, optional components, and speakers. Then go to
"Connecting the Antenna" below.
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.
1. Disconnect the cable from your vehicle's negative (-) battery
terminal.
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 that
the screw is not insulated from the chassis by a plastic part.
3. Connect the red +12V TO IGNITION 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 +12V TO BATTERY wire (with in-line 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 (such as
the stereo), and continuous power for the stereo's memory when the
ignition is turned off.
5. Connect the blue/white AMP REMOTE TURN ON 500 mA 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). Cut the loop at the end and strip about 1/2 inch of
insulation for connection.
Note: 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.
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 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.
Refer to the equalizer/booster's owner's manual for directions.
Connecting 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. If you are
using only one pair of speakers, follow Steps 1 - 4 only.
1. Connect the gray wire to the right front speaker's positive terminal.
This terminal is usually marked with a plus (+) sigh 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 (-) sigh, 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
