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.
Note: If the mounting area is too large, you might be able to mount the
stereo with the supplied gasket or 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 channel beneath the
vehicle's door facings by carefully removing the molding that holds the
carpet in place. After you route the speaker wires, replace the molding.
Making The Connections
The supplied harness with the 14-pin connector includes all the lead wires
you need to connect the stereo to ground, power, optional components, and
speakers.
IMPORTANT: Do not cut the lead wires. If you cut any wire, you cannot
obtain a refund or exchange on this product. However, your
local RadioShack store will provide warranty service if you
cut a wire and find the product is defective.
You might need additional wire, depending on your individual autosound
system, to complete the connections. Your local RadioShack store carries a
full line of wire and wire management accessories.
CAUTIONS: For added safety and to protect your stereo, disconnect the
cable from your vehicle battery's negative (-) terminal before
you begin.
You must connect the GROUND (-), +12V TO IGNITION, and +12V TO
BATTERY wires first then make all other connections as described
in the following sections before you plug the wire harness with
