INSTALLATION GUIDE
SB-J-LBRTY/12W3, JL AUDIO, Inc 2003 Sheet SKU#011168 Revision4/9/2003Page 1
for the
SB-J-LBRTY/12W3
(Freedom,Limited,Renegade,Sport)
This Stealthbox is a product which
requires professional installation skills and
tools.
Please read this installation guide thor-
oughly before beginning the project. It
will guide you step by step through the
installation. Several of the steps in this
process may require two people to
accomplish.
It is absolutely vital that the enclosure
be properly mounted to the vehicle
according to these instructions. Failure
to mount the enclosure properly pres-
ents 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) and
2) A loose enclosure presents a serious
safety hazard in the event of a collision
or sudden deceleration.
Please enjoy your JL Audio Stealthbox
responsibly.
STEP 1:
Open the rear door and remove
any contents and the retractable security
cover.
STEP 2:
The enclsoure will be mounted on
the driver’s side cargo area. Both cleats are to
be removed.
STEP 3:
To remove both cleats, you need to
remove both of the OEM rivets.
STEP 4:
With a 1/4” drill bit, drill out the
rivet’s head.Then with a punch out and ham-
mer, carfully tap out the rivet’s body.
STEP 5:
After the rivets are completely
removed, the cleats should pull up.They are still
going to be attached to the carpet.
STEP 6:
Unasnp the cleats to remove them
from the carpet.
*WARNING*
Please keep these cleats with the vehicle’s
owner.They will need to be reinstalled if they
remove the Stealthbox.

marker or pencil for this step.
Rear Cleat Location: Spread the carpet.

STEP 8:
Front Cleat Location: Spread
the carpet. Find the center between the two
holes, then measure 1/2” out from the holes
to the middle of vehicle.Then mark.
STEP 12: Hand thread the two supplied socket
cup set screws into the bottom of the Stealthbox,
leaving about 1” of each threaded rod exposed.
Make sure that the slotted end is exposed.
Place the Stealthbox into the mounting location. Be
careful guiding the threaded rods through the 1/2”
drilled holes.(If you’re not careful you will damage
the threads).
➔
STEP 13: With the Stealthbox in place and a sec-
ond person pushing down, it is time to mount the
Stealthbox into place.
Double check the socket cup set screws for proper
exposed length outside of the vehicle. Use a large flat
blade screw driver to adjust the threaded rod length.
The front threaded rod is not going to be easy to
access.There is a fast simple way and a more time
consuming way, please pick. Please read STEP 13(a)
and STEP 13(b) before mounting the Stealthbox
Enclsoure.
STEP 13(a): This is the fast simple way. Gather up
one supplied 3/8” hex nut, one supplied 3/8” lock
washer and one supplied 3/8” fender washer.
Place the hex nut into a 3/8” drive short socket(long
socket used in picture), dab a little dum-dum or hot
glue to the rim of the socket, place a supplied 3/8”
lock washer onto the socket, dab a little dum-dum
or hot glue to the rim of the 3/8” lock washer, then
place a supplied 3/8” fender washer on top. Make
sure that all middle holes of the mounting harware
line up. Carefully guide the mounting hardware and
the socket to the front exposed threaded rod.
STEP 9: With 1/2” drill bit and drill. Drill at the
marked locations from STEP 7 & STEP8
*CAUTION*
Before drilling make sure that you are not going to
be driling into gas lines, gas tank, brake lines, eletrical
wiring and what ever else that might cause a bad
day.
STEP 10: This is what your 1/2” drilled hole is
going to look like.This is the front cleat location.

STEP 13(b): This is the more time consuming,
but easier way to access the front exposed threaded
rod.You need to unbolt the over flow gas can. Please
make sure that you are careful and you do not tip
over this plastic tank. Do not do this while smoking.
The three arrows show the three mounting nuts
that have to be removed. Unbolt and carefully sup-
port this palstic tank.
After the tank is supported, place a supplied
3/8”fender washer, a supplied 3/8” lock washer then
a supplied3/8” hex nut in this order onto the thread-
ed rod.Thighten.
STEP 14: The rear exposed socket cup set screw
is a lot easier to excess. Place a supplied 3/8” fender
washer, a supplied 3/8” lock washer then a supplied
3/8” hex nut in this order onto thesocket cup set
screw.Thighten.
