Disconnect negative battery cable from battery.
Note: On vehicles equipped with dual batteries, disconnect negative battery cable
from both batteries.
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 amplifier and subwoofer power harnesses. Connect the
ring terminals of both harnesses to the power lug closest to the front of the vehicle and torque to 9 +/-
1.5Nm. Fig. 1
Note: Depending on year model, appearance of the power distribution area may
differ slightly from Fig. 5. Regardless, use the power lug closest to the front of
the vehicle.
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 of the large rubber grommet and
feed the power wires straight through the hole on the cabin side of the grommet. Fig.2
Install the white three pin power connector on the amplifier
power harness and 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.

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.
Using a panel removal tool, pry loose the driver’s side front and rear threshold panel along the bottom of
the dooropenings. Fig. 5 & 6
Pry loose the dash end panel on the driver’s side. Fig. 7

2017 Year Model Only – Module Relocation
(for all other year models, proceed to step 15)
Note: 2017 Year Model vehicles require the relocation of a module in order to gain
sufficient space to mount the amplifier. Follow steps 11-14 to relocate the factory
module.
Remove the two screws securing the factory module bracket under the driver’s side dash and pull the
module and bracket down. Fig.10
Secure the module to the provided relocation bracket exactly as shown in Fig.11.
Remove the four nuts securing the knee bolster under the steering column. Fig.12
Install the relocation bracket and module over the knee bolster studs as shown in Fig.13. Reinstall the
knee bolster and reinstall nuts and tighten to 9Nm. Secure the module wire harness by inserting the
factory wire retainer into the hole on the bottom of the relocation bracket.

Route the amplifier harness through the front of the console and across the dash toward the driver’s
kick panel area. The white connectors will connect to the amplifier.
Disconnect the radio speaker/power connector Fig. 15
Connect the radio speaker/power connector to the corresponding amplifier harness connector. Connect
the remaining amplifier harness connector to the radio. Make sure the connector is fully seated. Fig. 16
Connect the amplifier power harness three-pin connector to the
amplifier harness three-pinconnector.
Connect the subwoofer power harness two-pin connector to the
subwoofer harness two-pinconnector.
Connect the white two-pin signal connector on the subwoofer
harness to the white two pin connector of the amplifier harness.
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 black ground wire of both the amplifier and subwoofer harness to the bolt next to the park
brake pedal indicated in Fig 17 Torque to 9 +/- 1.5 Nm.

Subwoofer Installation
Open the storage compartment lid and locate the two knobs
underneath the rubber liner that secure the storage
compartment to the vehicle. Unscrew the knobs and lift the

Using a panel removal tool pry loose the screw cover on the driver’s side C and D pillar post cover and
remove the screws securing both covers. Pry loose the C pillar post cover and lay aside. Pry loose the
D pillar post cover, disconnect speaker wiring and lay aside. Fig 23
Using a pick tool, snap loose the cover on the driver’s side cargo D-ring to reveal the bolt securing the
D-ring and remove the bolt. Fig 24
Unscrew the cargo-net anchor knob on the driver’s side. Fig 25
Note: The knob may unscrew from the threaded stud. If so, use a pair of pliers to
remove the stud being careful not to damage the threads. Replace plastic knob
onto the stud for reassembly later.
Slide the driver’s side second row seatbelt trim cover up to reveal the seatbelt bolt and remove the bolt.
(Tahoe/Yukon only) Fig. 26 Torque to 45Nm.
Using a panel removal tool, pry loose the driver’s side quarter panel cover. Disconnect the rear 12-volt
accessory port wiring and the rear folding seat switch wiring (if equipped) and lay the quarter panel
cover aside in the cargo area.
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.

Locate the factory module bracket and remove the two nuts securing it. Fig 27
Pry the module wire retainers from the factory bracket. Fig 27
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 28
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 29
Using the supplied bolt and plastic fastener, install the smaller module over the top of the larger module
as shown in Fig 30
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 31
Remove the bolt indicated in Fig 31
Install the module relocation bracket as shown in Fig 32 and reinstall bolt.
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 33
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 34
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 35
