(120-2113) Installation Faxback Doc. # 62492
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 systems.
Which terminal in my vehicle's fuse box is for accessories?
How do I connect a wire to the fuse box?
Which of the stereo's wires is the power wire?
Which stereo wires are speaker outputs?
Also, be aware that installation in your vehicle might require cutting or
modifying your vehicle.
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.
CAUTION: Be sure to avoid obstructions behind the mounting surface.
Notes: This stereo is a DIN-E size unit that requires a 2-1/16 inches (53
mm) high by 7-3/16 inches (182 mm) wide by 6-11/16-inches (170 mm)
deep mounting area.
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.
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. After you route the wires, replace the molding.
Removing the Shipping Screw
The shipping screw helps protect the stereo's cassette player from being
damaged during shipment.
