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.

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.

If you choose to perform the installation yourself, it is absolutely vital that
the Stealthbox
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.

be properly mounted to the vehicle according to these

S T E P 1
These instructions are for both the short and long
wheelbase versions of this popular SUV.

Empty out the back of the vehicle so that you have a clean
area to work in.

Remove the pocket in the rear quarter interior trim panel on
the drivers side of the vehicle by pulling it up and out. The
wire to power the Stealthbox® needs to come from this open
area, now would be a good time to run that wire. Leave
enough extra to make it easy to make the connection to the
Stealthbox® before it is permanently mounted.

Looking down through the hole where the pocket had been,
notice the three studs installed at the factory. These studs
will be used to hold down the enclosure.

S T E P 3

The Triangular Plate will be positioned as shown with center
the hole closest to the stud pointing towards the center of
the vehicle..
