5.1 Upgrade
Installation
IMPORTANT! - Before starting, turn off the power to the subwoofer
and unplug the power cable.
Tools Required -
1.
Medium Phillips head screwdriver
2.
Wire cutters / or utility scissors
Step 1. Turn off the power to the subwoofer and unplug the power cord.
WARNING! Do not attempt to install the 5.1 Upgrade when the power
cord is connected!
Step 2. Using a Phillips head screwdriver, remove the 8 screws holding the
blank panel and remove the panel (as shown in the pictures below).
Step 3. Remove the clip holding the two wiring harnesses to the inside
panel.
Step 4. Bend the wire clip that was holding the wiring harnesses down and
parallel to the inside panel (shown below).
Step 5. Before proceeding to step 6 carefully locate both J18 and J10 on the
Upgrade Amplifier assembly. See Figure 1
Step 6. Plug the 3 pin connector into J10, which is located on the smaller
printed circuit board (pictured in Figure 1). The connector has a locking
tab that locks onto the raised plastic edge of the receptacle which faces the
outside edge of the board. Carefully press the connector onto this terminal,
until the connector locks onto the receptacle (pictured below).
NOTE: If you have to remove connector for any reason, depress the
locking tab and gently pull the connector out of the receptacle.

Step 7. Plug the 8 pin ribbon cable into the matching receptacle on the larger
PC board (J18 in Figure 1). The plug on the ribbon cable has two arrows on it
that match up with the two slots in the receptacle. Gently push the plug until
it is fully seated in the receptacle (picture below).
Step 8. Carefully tuck all the wires out of the way. If the three wire harness is
too long, use the supplied tie-wrap to bundle the excess wire.
Note: Make sure no wires are trapped between the backplate and the
cabinet.
Step 9. Put the upgrade amplifier into the opening on the back of the
subwoofer and attach it to the subwoofer cabinet using the 8 screws that were
removed in step 2 (pictured below). As mentioned in the note above, make
sure no wires are trapped between the backplate and the cabinet.
WARNING! Do not over tighten the screws holding the amplifier to
the subwoofer, or you may strip them. If you are using an electric
screwdriver or variable speed drill, set them to the lowest torque
setting.
