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 pres-
ents 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) and
2) A loose enclosure presents a serious
safety hazard in the event of a collision
or sudden deceleration.
STEP 4: Unbolt the bracket that is already
attached to the Stealthbox.
STEP 5: With the supplied hardware, attach
the bracket to the rear wall.
STEP 6: Attach speaker wire to the
Stealthbox terminal and check the woofer for
proper operation.
Set mounting hardware to the side.This will
be used in later steps.
Place a 1/4” lock wash and a 1/4” flat washer
onto each #6x30mm-1mm bolt.
Place the bolts through the bracket and slide
one 1”Lx1”ODx3/8”ID spacer onto each bolt.
Line up the bolts to the factory threads and
secure tightly.
Please enjoy your JL Audio Stealthbox
responsibly.
