mounting bracket. Every effort should be made to
avoid locating the speaker behind a sound absorptive
barrier (e.g., facing upward under the seat or behind a
dashboard panel).
CAUTION Do not install either the speaker or DHFA
unsupported to prevent shifting of the unit which could
interfere with the proper operation of the vehicle.
Always use the supplied mounting hardware.
Control/Power Cable Routing
Many vehicles are equipped with wire troughs in the
door sills. If the vehicle has this feature, use it to
provide maximum protection for the cables and to
simplify installation. In vehicles without wiring troughs,
the power cable must be routed where it will be
protected from pinching, sharp edges, and crushing.
To avoid interference with the vehicle's electronics, do
not run cables above the catalytic converter or near
the vehicle's electronic modules. Use grommets
whenever a cable must pass through a hole in a metal
panel. No matter what method of cable routing is
implemented, all in-line connectors must be kept
accessible.
The mobile telephone system is designed to operate
in negative ground 12-volt electrical systems only.
To minimize electrical noise that interferes with the
cellular telephone operation, be sure to check the
condition of the ignition wiring and the connections to
the vehicle battery. All wire connections should be
clean and tight.
