(120-2154/55) Installation Faxback Doc. # 48529
This document contains instructions for both Cat. No. 120-2154 and
120-2155 stereos. (You can find the Cat. No. of your model on the top
of the stereo.) 120-2154 has a LOUD button while 120-2155 has an FSM
button. Unless otherwise noted, these are the primary differences
between the two units listed.
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 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 connecting 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 autosound stereo system is a DIN-E size unit that requires a
2-inch high by 7-1/2-wide by 7-1/4 inch deep (57 x 190 x 186 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
