INSTRUCTIONS
1. Insure your work area
is clear of objects that can
damage the enclosure’s
steel grill then set
the enclosure onto
its front.

2. Remove the 10 hex head
bolts and washers that attach
the rear access panel. Do not
discard this hardware.

NOTE: The illustrations for Steps 3 through 8 are as viewed from the bottom of the enclosure.

3. Carefully lift and turn over the access panel, not damaging
the internal wiring, and rest it on the back of the enclosure.

4. Orient the
bi-amp crossover
board so its large
inductor is toward the
input and the smaller
inductor away from the
wooden stiffener.

Position the bi-amp
crossover board tight
against the stiffener
and the wooden
input backer.

5. With it tight against
the stiffener and input backer,
screw the bi-amp crossover board
in this position with the 5 supplied
wood screws.

6. Unplug the inline connector between the access
panel and the drivers.

7. Connect the male connector
from the access panel to the
female connector from the
bi-amp crossover board.
Connect the female connector
from the drivers to the male
connector from the bi-amp
crossover board.
Ensure all connectors
are fully mated.

8. Cut the red and black wires soldered to
the 3-pin connector on the input. Unplug
the other ends from the terminal strips on
the existing crossover board. You may discard these wires.

9. Reposition the access panel onto the back
of the enclosure making sure internal wiring is
not pinched. Reinstall and tighten the 10 hex
head bolts and washers removed in step 2.
