This Stealthbox is a product which
requires professional installation skills and
tools.
Please read this installation guide thor­oughly 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 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) 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:

Place the supplied 3"x3” wax square,
sticky side down, on the rear driver-side car­pet as shown in the photo at right.

Insert both supplied socket cup set screws
into the threaded inserts on the under side of
the Stealthbox.

Allow about 1./2” of the socket cup set screw
to protrude to the outside.

STEP 2:

Place the Stealthbox into its mount­ing location, making sure that it fits snugly
against all panels.

Once aligned properly, push down firmly on
the Stealthbox, in order to make a clear
impression on the wax square with the socket
cap screws on its underside.

Remove the enclosure from the vehicle care­fully by lifting it up and out so as not to disturb
the sheet wax.

STEP 3:

*Check under the rear of the
vehicle to make sure there are no
loose wires, brake lines or fuel lines
prior to drilling through the sheet
metal.

Always wear eye protection when

drilling.

*

Using a 1/2" carbide drill bit, drill a hole centered on
the impression on the sheet wax.

Remove the wax square and trim the excess carpet
from the hole you've just drilled.

STEP5:

Back out the socket cap screw to
allow 1-1/2” to protrude out of the
Stealthbox.

Place the enclosure into its mounting location taking
care to route the speaker wire so that it will not get
stuck between the enclosure and the vehicle trim
panel (bad fit) or come into contact with the
woofer (bad sound).

STEP6: Before tightening the nut, apply a bead
of silicone sealant between the flat washer and the
vehicle's sheet metal to prevent leaks.

*IMPORTANT* Once the bolt is tightened, spray
undercoating onto the bolt head to prevent rust,
leaks and loosening of the bolt over time. Failure to
do so may result in corrosion and could present a
safety hazard.
