Installation Guide:

This Stealthbox is designed to mount in the right-rear corner of the hatch area and is a product which
requires professional installation skills and tools. We highly recommend that an authorized
JL Audio dealer performs the installation.

Please read this installation guide thoroughly before beginning the project. It will guide you step by
step through the process. Some steps may require two people to accomplish.

It is absolutely vital that the Stealthbox be properly mounted to the vehicle according to these instruc­tions. Failure to mount the enclosure properly will result in inferior bass performance and potential
danger in the event of a collision or sudden jolt to the vehicle.

STEP 1: Permanently remove the retainer net from the
storage pocket on the passenger side trim panel (if present).

STEP 2: Run speaker wires to the corner of the hatch where
the Stealthbox will be located.

STEP 3: Measure distances for placing the wax sheets as
follows: The front square should be placed on the wheel well
approximately 18" from the back of the storage pocket open­ing. The rear square should be placed approximately 3" from
the back of the storage pocket opening on the floor of the
cargo area (see next step).

STEP 4: Peel the backing from the supplied sheet wax squares
and place them, sticky side down, centered on the locations
measured in STEP 3.

STEP 5: Thread the supplied bolts into the inserts molded into the Stealthbox and tighten fully.

STEP 6: Place the Stealthbox in its mounting position. Make sure

that it is pushed snugly against the vehicle's side panel. Once
positioned, press down firmly on the Stealthbox to make impres­sions on the sheet wax squares with the mounting bolts.

STEP 7: Remove the enclosure gently. There should be a clear mark on each wax square which you will use
as locators for drilling the mounting holes.

STEP 8: Check under the truck for any loose brake lines, fuel lines or other hazards before drilling any holes.
Also check for adequate clearance between the wheel well and the tire so as not to drill through it. Also make
sure that the vehicle exhaust is cool before proceeding with the mounting of the Stealthbox!

STEP 9: Drill a 1/2" diameter hole, using a carbide bit, through
the floor pan of the vehicle using the indentation in the sheet wax
as a guide. Make sure the holes are centered on the mark and
that you hold the drill straight. Always wear eye protection when
drilling.

STEP 10: Repeat the same process described in STEP 9 for the
hole in the wheel well. Make sure you stop the drill as soon as it
goes through so as not to damage the tire!

REMOVE BOTH WAX SQUARES ONCE DRILLING IS COMPLETE
Enlarge the hole in the plastic trim panel to 3/4" diameter to allow

the insert in the bottom of the Stealthbox to contact the sheet
metal of the wheel well.

STEP 11: Trim the speaker wire to length and connect it to the enclosure's terminal cup observing proper
polarity. Before proceeding to the next step, turn the system on and test the enclosure's operation.

STEP 12: Place the Stealthbox into its mounting position, tucking the excess speaker wire neatly out of sight.

STEP 13: While one person holds the Stealthbox in place inside the truck, bolt the enclosure into place from
underneath using the supplied hardware. Before tightening the bolts, apply a bead of silicone sealant between
the flat washer and the vehicle's floor pan. Once this is done, tighten the bolts evenly. See diagram below.
