side of the stereo to 4CH. Then connect the speakers to the supplied
harness as follows.
1. Connect the harness' gray wire to the front-right speaker's positive
(+) terminal.
2. Connect the harness' gray/black wire to the front-right speaker's
negative (-) terminal.

CONNECTING TO OTHER COMPONENTS
You can connect other audio components (such as an equalizer/booster or
amplifier) to your stereo's speaker or line level outputs. Check the
component's owner's manual for instructions on connecting it to a stereo
and to power.
If you want to turn the optional component on and off with the stereo,
you can connect it to the stereo's dark blue/white wire (labeled AMP
REMOTE TURN ON). This wire does not provide power to the component. It
simply turns it on or off. If you do not use this wire, use a wire tie
to keep it out of the way.
If your vehicle has an automatic antenna, connect the AMP REMOTE TURN ON
lead to the vehicle's power Antenna lead.
Note: The optional component must be designed for use with an amp remote
turn on lead for the above connection. See the optional component's
owner manual.
CONNECTING TO YOUR CAR PHONE
If you want the stereo's sound to mute when you use your car phone,
connect the pink/white wire to your car phone's mute terminal.
CONNECTING TO POWER AND YOUR VEHICLE'S ANTENNA
1. Connect the stereo's black ground wire to a metal screw attached to
the vehicle's frame. Be sure the screw is not insulated from the
chassis by a plastic part.
2. Connect the stereo's yellow wire (with an in-line fuse holder and
MEMORY BACKUP LEAD label) to your battery's positive (+) terminal or
to a non-switched fuse terminal (a terminal that the vehicle's
ignition does not turn on and off). This connection provides 12
volts of continuous power for the radio's memory and the security LED
when the ignition is turned off.
3. Connect the wire labeled POWER LEAD B (+) (with an in-line fuse
holder) to the accessory (ACC) terminal on your vehicle's fuse block.
This connection provides power to the stereo when you turn on the
ignition, and turns off power when you turn off the ignition. This
prevents your vehicle's battery from draining if you leave the stereo
on and turn off the ignition.
4. Connect the vehicle's antenna cable to the stereo's large antenna
connector.
When all connections are complete, reconnect the battery cable.
TESTING THE CONNECTIONS
After you connect the speakers, power wires, and antenna, turn on your
vehicle's ignition and test the stereo to be sure it works.
If the stereo does not work, immediately unplug the harness. Recheck
your connections or have a professional automotive audio installer
complete the installation.
If the stereo works, disconnect the cable from the vehicle battery's
negative terminal and continue with installation.
MOUNTING THE STEREO
IF your vehicle does not have a prepared opening for a flat face (DIN E)
component, you must use an in-dash installation kit. Installation kits
for many local Radio Shack store.
If you use an in-dash installation kit, follow its supplied instructions
to mount the mounting sleeve.
If you are using an in-dash installation kit, follow these steps to mount
the stereo.
1. Disconnect the cable from the vehicle battery's negative (-) terminal.
2. Temporarily disconnect the wiring harness and antenna.
3. Insert the mounting sleeve into the dash opening and secure it by
bending the locking tabs out with a screwdriver.
4. Reconnect the wiring harness and antenna through the sleeve.
5. Slide the stereo into the sleeve until it locks into place.
