  SB-N-PTHFNDR/10WØ Stealthbox™
     Fits 1996 - 1999 Nissan Pathfinder
and Infiniti QX4
Installation Guide:
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 and 2) A 
loose enclosure presents a serious safety hazard in the event of a collision or sudden deceleration.
STEP 1: In the hatch area, pull up the carpet from the floor on 
the driver side to expose the padding underneath.
STEP 2: Place the Stealthbox in its mounting position.
STEP 3: Cut the padding along the edge of the Stealthbox.
After final installation, the Stealthbox should sit only on a layer 
of carpet so that it more easily couples to the body of the 
vehicle.
STEP 4: Remove the Stealthbox from the vehicle, then remove 
the padding that was cut off in the previous step.
STEP 5: Adjust the cargo hook so that it is pushed forward. If 
this step is neglected the Stealthbox may not fit properly and 
the hook will be unusable.

STEP 6: Remove the evaporative fuel recovery canister from 
under the vehicle. To do this first remove the three 12mm bolts 
holding the canister in place. Then carefully disconnect all the 
hoses and wires attached to the canister. Remove the canister.
STEP 7: Thread the supplied 3/8" X 1 1/2" bolts into the 
threaded inserts in the Stealthbox. Tighten fully.
STEP 8: Place the supplied 3" X 3" wax squares, sticky side 
down, in the area of the Stealthbox mounting holes as shown.
STEP 9: Place the Stealthbox in position. Press down on the 
Stealthbox to leave a clear indent in each wax square. Remove the 
Stealthbox.
STEP 10: Check under the vehicle to be sure there are no loose 
brake lines, fuel lines, etc. that may be contacted while drilling.
CAUTION: Always wear eye protection when drilling!
STEP 11: Drill 1/2" diameter hole through the floor of the vehicle
in the location of the indentation in each of the wax squares.
STEP 12: Remove the wax squares from the vehicle.
STEP 13: Place the carpet back in its original position. Make an
"X" shaped incision in the carpet above each mounting hole.

STEP 14: Run speaker wire to the Stealthbox location. Trim to 
proper length and attach to the Stealthbox. Test the operation of 
the Stealthbox.
STEP 15: Place the Stealthbox in its mounting position. While one 
person positions the Stealthbox from inside the vehicle a second 
person should thread the supplied 
3/8" X 1 1/2" bolts, fender
washers and lock washers into the Stealthbox. Apply a bead of 
sealant between the washers and the floor of the vehicle to prevent leaks (see diagram at right).

STEP 16: Replace the canister making absolutely sure all lines, hoses, and wires have been reconnected.
IMPORTANT!!!
Once the bolts are tightened, spray undercoating onto the bolt heads to prevent rust, leaks and 
loosening of the bolts over time. Failure to do so may result in severe corrosion and may present a 
serious safety hazard.
This completes the installation.
