(120-2117) Installation Faxback Doc. # 57141
Before You Begin The Installation
Before you install your stereo, we recommend you read through 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 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?
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.
Note: Before permanent installation, 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. Place the stereo as close as possible to the selected mounting
location when making the temporary connections.
CAUTION: Be sure your speakers can handle 14 watts of power (7 watts per
channel). Each speaker must have an impedance of at least 4
Ohms. Your local RadioShack store carries a full line of
speakers.
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 stereo
mounting area. This auto-sound stereo system is a DIN-E size unit that
requires a 2-1/16-inch high by 7-3/16-inch wide by 6-11/16-inch deep (52 x
182 x 170 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.
