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

®

 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.

S T E P   1

Remove anything stored behind the rear seats and fold both 
seats forward.  

If the truck is equipped with the OEM 

Subwoofer

, it must be removed and the rear panel will 

need to be cut or, replaced with the panel from Toyota for 
a truck not equipped with a OEM subwoofer.  Call Technical 
support  (954) 443-1100 for further details if needed.

Test Stealthbox® for proper operation.

Using a Phillips head screwdriver remove the woofer from 
the enclosure.  

The grille does not need to be removed 

from the woofer!  

The grilles were removed in later pictures 

for this document but they do not need to be for this 
installation.

S T E P   2 

Along the outside of the plastic panel that covers the back 
of the cab on the drivers side, locate the seam between 
the back and, side panels.  Line up the first (or only) 
enclosure with this seam. 

If installing two enclosures, verify that there is adequate 
room between the first enclosure and the elevated part 
of the rear panel on the passengers side  (as seen in the 
photo for 

step (1))

 to fit the second enclosure.

Using a 1/8" drill, use the hole in the enclosure centered 
behind the woofer as a guide, to drill a hole through the 
plastic 

(and only the plastic)

 that covers the back of the 

cab.  

                      *CAUTION*

 

Before drilling, always make sure that you are not 

going to be drilling into any gas lines, brake lines, 

transmission lines, electrical wiring, exhaust systems 

or anything else that might cause a reduction in 

your weekly pay.   Always wear eye protection when 

drilling.
