If you choose to perform the installation yourself, it is absolutely vital that
the Stealthbox® be properly mounted to the vehicle according to these
instructions. Failure to mount the enclosure properly presents two problems:
1) The sub-bass performance will suffer due to the movement of the enclosure
caused by the force exerted by the woofer(s).
2) A loose enclosure presents a serious safety hazard in the event of a collision
or sudden deceleration.

ESTIMATED TIME:
4 HOURS
STEP 1
Disconnect the negative cable from the battery terminal,
then empty out the trunk of the car so that you have a clean
area to work in.
Thank you for choosing a JL Audio Stealthbox® for your automotive sound system. With proper installation, your new
vehicle-specific enclosed subwoofer system will deliver years of listening pleasure.
STEP 2
Lift the floor, remove the compartmented foam spacer this
will not remain in the vehicle.
We strongly recommend that you have your new Stealthbox® installed by your authorized JL Audio dealer. The
installation professionals employed by your dealer have the necessary tools and experience to disassemble and
reassemble your vehicle properly. Also, keep in mind that your warranty coverage extends to 2 years if your system is
installed or approved by your authorized JL Audio dealer. If you prefer to perform your own installation, please read
this installation guide completely
before beginning the process.
STEP 3
Remove the tool kit that resides inside the spare tire and the
spare tire itself, set aside the hardware as it will be re-used.

STEP 4
From the rear of the vehicle looking into the spare tire well,
position the three Wax Squares as shown, make sure that the
Wax Squares adhere to the floor well so that they don’t shift
while making impressions in them.
STEP 8
Gently set the Stealthbox® in place centering the Spare Tire
Platform in the recess. For the Slampak® installation, the
amplifier will already be mounted on the enclosure. Once
the Stealthbox ® is in place, put enough pressure on it to
cause the three Allen Head Set Screws to mark the Wax
Squares. Remove the Stealthbox® from the vehicle making
sure that the Wax Squares stay in place on the floor of the
spare tire well.
STEP 5
Thread the three included Allen Head Studs into the bottom
of the Stealthbox® as shown, leaving approximately 1/2”
exposed.
STEP 9
Using a 1/2” drill bit, drill through the three marks in the Wax
Squares.
Before drilling, always make sure that you are not
going to be drilling into any gas lines, brake lines,
tires, transmission lines, electrical wiring, exhaust
systems or anything else that might cause a
reduction in your weekly pay.
Always wear eye protection when drilling!
STEP 6
Mount the 8mm x 38mm Coupling Nut to the steel strap as
shown using the 8mm x 16mm Hex Cap Screw and 5/16”
Split Lock Washer to secure the Coupler to the Custom
Mount Strap.
Mount the Custom Mount Strap with the Coupling
Nut attached to the Stealthbox® on the top side of the
Stealthbox, in the spare tire recess, as shown using the two
included 1/4-20 x 2” Phillips Head Screws.
STEP 7
Locate the three holes in the Spare Tire Platform, align them
with the three threaded inserts in the Stealthbox® and
mount the Spare Tire Platform to the Stealthbox® using the
three included 1/4-20 x 1-1/2” Allen Head Bolts.

STEP 10
Set the Stealthbox® back into the car, positioning it so that
the Allen Head Set Screws come through the holes drilled in
Step 9. From under the vehicle, secure the Stealthbox® in
place by putting a Fender Washer, Split Lock Washer and Hex
Nut on each Allen Head Set Screw. Progressively tighten all
three studs as if you were changing a tire so that all three get
tightened evenly.
STEP 11
Set the spare tire in place and secure it through the threaded
coupler (seen in Step 6) using the original hardware that
secured the tire in place before the installation of the
Stealthbox®

end of the factory harness that was removed from the head
unit. Plug the RCA Cable into the female pigtails in the THarness. Route the T-Harness, RCA cable, and HD-RLC cable
together, over the glove compartment and toward the kick
panel. Use cable ties to keep the wiring secure and out of
the way of moving parts.
Follow the instructions that came with the HD-RLC to
properly mount the level control in the desired location, we
suggest that it be mounted near the radio.

removing the small triangular cover at the top of the door.
Pull to unclip it, and set it aside.
STEP 40
Using a punch tool and hammer, punch out the four rivets
holding the speaker to the door. This will make drilling the
rivets in the next step easier.
STEP 37
Behind the interior handle, open the screw cover using
a small pick tool. Remove the screw, and slide the cover
forward and off the door. Set it aside.
STEP 41
Using a 3/16” drill bit, drill out the rivets, and remove the
speaker from the door. Enlarge the rivet holes using a 1/4”

tires, transmission lines, electrical wiring, exhaust
systems or anything else that might cause a
reduction in your weekly pay.
