Connect the speaker wires. See the wiring diagram (
15 page 28) for the proper hookups. Follow the diagram
carefully to avoid damaging the speakers and the stereo
unit.
The speakers used must be able to handle more than 50
W of audio power. If using an optional audio amplifier,
the speakers should be able to handle the maximum
amplifier output power. Speakers with low input ratings
can be damaged. Speaker impedance should measure
4–8 Ω, which is typically marked on most speakers.
Lower or higher impedance speakers will affect output
and can cause both speaker and stereo unit damage.
Battery
Connect the yellow battery lead to the correct radio wire
or to the battery fuse port on the fuse block.
Antenna
Connect the antenna by plugging the antenna lead into
the antenna receptacle.
Equipment
Connect any optional equipment such as an amplifier,
according to the instructions furnished with the
equipment. Leave about 12" (30 cm) of distance
between the speaker leads/amplifier unit and the
antenna/antenna extension cord. Read the operating and
installation instructions of any equipment you will
connect to this unit.
Power
Connect the red power lead to the correct car radio wire
or to the appropriate fuse port on the fuse block.
If the stereo unit functions properly with all these
connections made, disconnect the wires and proceed to
the final installation.
Final Installation
Lead Connections
Connect all wires, making sure that each connection is
insulated and secure. Bundle all loose wires and fasten
them with tape so they will not fall down later. Now
insert the stereo unit into the mounting collar.
Congratulations! After making a few final checks, you're
ready to enjoy your new auto stereo system.
