Wiring the Speaker Mounting Plate
NOTE: Mounting hardware is not provided.
1. Route the two speaker wires through the rear of the mounting plate and attach the
wire ends to the quick connect contacts using a small screwdriver (see the illustration
below). Be sure to observe the correct polarity.
NOTE: The positive (+) connector and the negative (-) connector are marked on the
mounting plate.
ATTENTION: Use the appropriate mounting screws. The screw heads must not protrude
more than .074” (1.9 mm) above the screw holes in the mounting plate. If the screw head
protrudes too far above the mounting plate surface, damage to the speaker may occur
when the speaker is attached (see the figure below).
