Wire Routing
Remove the red battery terminal cover and thenthe power distribution cover next to the battery on the
passenger’s side.
Remove the fuse from the fuse holder on the subwoofer power harness. Connect the ring terminal of the
subwoofer harness to the power lug identified in Fig 10. Torque to 9 +/- 1.5Nm.
Route the power wire along the fire wall to the factory grommet on the driver’s side and secure withwire
ties.
Using a razor knife, make a cross shaped incision in the protrusion large rubber grommet and feed the
power wire straight through the hole on the cabin side of the grommet. Fig11
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 12
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.
Connect the subwoofer power harness two-pin connector to the subwoofer harness two-pinconnector.
Connect the black ground wire of the subwoofer harness to the bolt next to the parking brake pedal
indicated in Fig 13 Torque to 9 +/- 1.5 Nm.

If the vehicle is equipped with a base audio system, (non-Bose®)
find the brown with blue stripe wire and the blue wire that are
twisted together in the factory harness near the parking brake
pedal. Install the supplied wiretaps onto the vehicle wires.
Connect the green wire if the adaptor harness to the blue wire of
the vehicle harness and the brown wire of the adaptor harness to
the brown/blue stripe wire of the vehicle harness. Fig. 14
Note: If vehicle is equipped with premium audio (Bose®) refer
to input connection indicated later in this manual.
Note: There are input connection points on both ends of the subwoofer harness. Only one of the
two connection points will be used depending on whether the vehicle is equipped with premium or
base audio.
Connect the white two-pin connector of the adaptor harness to white two-pin connector of the subwoofer
harness.
Continue routing the subwoofer harness down the driver’s side of the vehicle to the rear quarter panel.
Open the cover of the wire tray along the threshold of the door, install wire and replace the tray cover.
Subwoofer Installation
Locate the factory module bracket and remove the two nuts securing it. Fig 15
Pry the module wire retainers from the factory bracket. Fig 15
Note: Depending on the vehicle trim level, there may be one or two modules attached
to the bracket. The module(s) will need to be relocated using the supplied
relocation bracket in order for the subwoofer to be installed.
Note: Do not disconnect the module wiring. Modules wiring is shown disconnected
in some pictures only for clarity of installation.
Pry out the center portion of the plastic retainer securing the smaller module and then the outer portion.
Remove the module from the factory bracket. Fig 16

If equipped, remove the larger module by snapping it out of the factory bracket.
Pull the factory module bracket from the metal and discard.
If equipped with two modules, slide the larger module into the relocation bracket first as shown in Fig 17
Using the supplied bolt and plastic fastener, install the smaller module over the top of the larger module as
shown in Fig 18
Note: The connectors on the smaller module face the opposite direction as the
connectors on the larger module. The smaller module mounts the same way
regardless of whether or not there is a second module.
Unscrew the jack tool-bag knob and remove the tool-bag. Fig 19
Remove the bolt indicated in Fig 19
Install the module relocation bracket as shown in Fig 20 and reinstall bolt.
If the vehicle is equipped with factory premium audio (Bose®),
locate the amplifier behind the jack mounting bracket. Disconnect
the connector indicated in Fig 21
Find the gray/black and blue/gray wire in the connector and install
the supplied wiretaps onto the wires. Connect the green wire of

Reconnect the amplifier connector to the amplifier.
Connect the white two-pin connector of the adaptor harness to the white two-pin connector of the
subwoofer harness.
There are two lower subwoofer brackets provided depending on the wheelbase of the vehicle. For
Tahoe/Yukon use the longer bracket. For Suburban/Yukon XL use the shorter bracket. Determine the
lower subwoofer bracket needed and attach it to the subwoofer using the supplied nut and bolt as shown
in Fig 22
Note: The lower subwoofer bracket should overlap the bracket attached to the
subwoofer as shown. The nut should be installed on the side closest to the
subwoofer. Leave the nut and bolt slightly loose so the lower bracket can
slide.
Remove the nut that secures the jack bracket indicated in Fig 23
Pull the factory wire harness slightly away from the metal in order for the subwoofer upper bracket to pass
under the factory wire harness. Fig 24

Addendum
•Vehicles affected: All 2014 - up Chevrolet Silverado/GMC Sierra 1500/2500/3500
trucks equipped with ANC (Active Noise Cancellation)
•Note: In order for the subwoofer to operate correctly, Active Noise
Cancellation (only available on trucks equipped with 6.2L engine) must be
disabled. Due to the increased output of the Kicker® subwoofer, failure to
disable ANC will result in a “feedback” issue between ANC and the subwoofer
at certain RPM’s. Disabling ANC is easy and can be reversed if the Kicker®
subwoofer is ever removed from the vehicle.
•ANC can be disabled in one of two ways.
1) Follow the following steps in the Disabling Active Noise cancellation
section.
2) Visit a GM dealership and have the Active Noise Cancellation disable
through the Audio Control Module*.
*Will require additional fee.

Disabling Active Noise Cancellation (ANC)
1. Using a panel tool, remove the screw cover from the driver’s side visor. Fig. 1
2. Remove the three screws securing the visor, pull visor loose and disconnect wiring.
3. Open the screw covers on the grab handle above the driver’s door, remove the two screws and pull loose
handle. Fig. 2
4. Snap loose the driver’s side A pillar cover slightly. Cover doesn’t need to be completely removed. Fig. 3
5. Pull down the rubber door seal along the top of the driver’s door. Fig. 4
6. Pull down slightly on the headliner to expose the black adhesive tape covering the microphone.
7. Carefully remove the black tape so that it can be re-applied. Fig. 5
8. Find and disconnect the microphone wiring. Disconnecting just one of three microphones will disable the ANC.
Fig. 6
9. Re-apply the black adhesive tape over the microphone and connecters.
10. Re-install previously removed parts in reverse order.
