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 of the stereo's wires is the power wire?
Which terminal in my vehicle's fuse box is for accessories?
How do I connect a wire to the fuse box?
Which stereo wires are line-level outputs and which 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.
Notes:
This autosound stereo system is a DIN-E size unit that requires a
2 1/4 inch (57 mm) high by 7 1/2 inch (190 mm) wide by 7 1/4 inch
(186 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
Radio Shack store. Follow the installation kit's instructions to
mount the stereo.
Cautions:
Make sure your vehicle's mounting area is at level as possible.
If you cannot mount the stereo exactly level, make sure the stereo
will not tilt up more than 30 degrees when it is mounted.
Be careful to avoid obstructions behind the mounting surface.
