INSTALLATION GUIDE
for the
SB-SC-XB/12W3v3
SKU# 94421
2007 & Up Scion xB
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.
STEP 1
Remove anything stored in the passenger rear corner of
the trunk so that you are working in a clean environment.
Unpack the Stealthbox® and test for proper operation
before continuing!
The wiring for the Stealthbox® should go from the seam
between the seat back and the floor to the amplifier
location.

STEP 2
Place the wax square as shown onto the interior panel.
Remove the two cargo anchors from the mounts as
indicated by the arrows. These anchors will be installed on
the Stealthbox.
STEP 3
Locate the threaded insert for the mounting bolt, thread the
3/8-16 bolt in so that only approximately 1/2” remains out
(see Detailed picture on next page).

STEP 6
Make sure that the pilot hole will allow the 3/8” bolt to pass
through it. Use a piece of tape to secure the 1” spacer in
place so that it won’t fall as the bolt is inserted from below
into the enclosure.
STEP 5 *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.
Using a 1” hole saw, use the mark left in the wax square as
center, drill and, saw through the plastic panel. After going
through the plastic panel, continue to drill so that the pilot in
the center of the hole saw goes through the metal inner fender.
DO NOT USE THE SAW THROUGH THE INNER FENDER,
ONLY GO DEEP ENOUGH TO MAKE THE PILOT HOLE!
STEP 4
Set the enclosure in place, apply pressure towards the
outside and, front of the vehicle (as arrows indicate) so that
the bolt extending from the enclosure produces a recess in
the wax square, remove the Stealthbox®. Remove the bolt
from the Stealthbox®.
STEP 3 (DETAIL)
Close-up of bolt protruding from enclosure. If bolt does not
leave an impression in the wax square in STEP 4, back it out
so that more is sticking out of the Stealthbox® until it leaves a
deep enough impression to use as a guide.

STEP 8
From inside the fender well, insert the bolt, split lock washer
and fender washer through the hole that was just drilled, up
through the spacer that is taped in place and thread it into
the Stealthbox® tighten it down so that it’s quite snug.
STEP 9
Mount the cargo anchors the were removed in STEP 2 to
the Stealthbox® using the two 1/4-20 x 1” bolts and, 6mm Flat
Washers. Do not use rachet type straps on these anchors as
they are only attached to the vehicle by the bolt that secures
the Stealthbox®. Use only the OEM supplied cargo net!

can listen to it all you want (cleanup your workspace first)!
