1. Disconnect negative battery cable.
2. Make sure supplied fuses are not installed in fuse holders. Open the battery distribution cover
and connect the subwoofer power wire and the amplifier power wire to the stud pictured in
figure 1 depending on which distribution block you have. Torque to 4.7Nm (42in-lb)
3. Route the power harnesses toward the firewall and secure with supplied wire ties.
4. Make a small incision in the grommet on the driver
side of the firewall and pass the power harnesses
into the cabin. Some models may have a small
nipple that can be cut off rather than making an
incision. Fig. 2
5. Install the white three pin power connector on the
amplifier power harness. Close the retainer. Fig. 3
Note: The terminals are keyed so that they only
install one way. If the terminal doesn’t want to
slide completely into the connector, it may
need to be rotated 180 degrees. It does not
matter which red wire goes in what position of
the connector.
Tip: Using a piece of stiff wire can help
in feeding the wires through the
grommet. Poke the stiff wire through
from inside the cabin and then tape the
power harnesses to the wire. Try to tape
the power wire so that the metal
terminals are not all trying to pass
through the grommet at the same time.

6. Install the black two pin power connector on the
subwoofer power harness by first inserting the
terminal fully into the connector and then
depressing the blue retainer. Fig. 4
Note: Make sure the blue retainer in the center
of the connector is not depressed –it should
be flush with the front of the connector. If the
retainer is depressed, the terminal will not fully
seat in the connector body. Make sure the
terminal is installed into position 1 on the
connector body. There should be a block-out plug installed in position 2 in order to
prevent the terminal from being installed into the wrong position on the connector.
Radio Removal
7. Pull loose the radio bezel. Fig. 5
8. Remove the four screws securing the radio display/HVAC control panel. Fig. 6

connector.
32. Route the subwoofer input connector (two-pin white) under the dash toward the passenger side
and connect it to the multi-channel amplifier connector.
33. Ground the subwoofer harness to the bolt securing
the left side of the dash. Fig. 22 Tighten to 19Nm
(14ft-lb)
34. Route the subwoofer harness along the driver side door openings. Pull harness under carpet
and through hole near rear seat frame on the driver side. Fig. 23
35. Make two ½ inch long cuts in carpet directly below the metal brace pictured in Fig. 24. Only cut
through the carpet layer, and not the insulation. The cuts should be approximately ½ inch apart.
36. Slide one of the supplied wire ties under the loop of carpet created in the previous step and
secure the harness to the carpet loop. Fig.25
37. Connect the subwoofer harness to the subwoofer. After connection, secure connector to

Troubleshooting the Kicker Integrated Systems
If you experience a problem once the subwoofer or amplifier are installed use this guide to locate the trouble.
The radio is working, but the Subwoofer is not working:
 Check the battery voltage to make sure it is not discharged below 11 volts.
 Check the negative battery cable to see if it has been securely tightened back on the battery.
 Check the inline fuse located near the battery to make sure it is plugged in completely, and not blown.
 Check the inline +12 volt power connector near the firewall to make sure it is plugged in securely.
 Check the inline connectors near the subwoofer enclosure to make sure they are plugged securely.
 Check the ground wire connection to make sure it is tightly secured to the proper ground in the vehicle.
 Check the audio input signal connection to make sure it is secure and connected to the proper wiring.
 Test with different music in case there is no low frequency audio in the initial sound check.
There is a problem with the multi-channel stereo amplifier:
 Check the battery voltage to make sure it is not discharged below 11 volts.
 Check the negative battery cable to see if it has been securely tightened back on the battery.
 Check the inline fuse located near the battery to see if it is plugged in completely and not blown.
 Check the multi-pin connectors at the back of the radio and at the amplifier chassis to make sure they are
plugged all the way in.
 Check the ground wire connection to make sure it is tightly secured to the proper ground in the vehicle.

Splicing Copper Wire Using Splice Sleeves
Special Tools:
• EL-38125-10 Splice Sleeve Crimping Tool
• J-38125-5A Ultra Torch Special Tool
• J-38125-8 Splice Sleeve Crimping Tool
NOTE: The DuraSeal splice sleeves have the following 2 critical features:
• A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a
sealing adhesive inside.
• A cross hatched (knurled) core crimp provides the necessary low resistance contact integrity
for these sensitive, low energy circuits.
Use DuraSeal splice sleeves where there are special requirements such as moisture sealing. Follow the
instructions below in order to splice copper wire using DuraSeal splice sleeves.
