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: Thread in the supplied tsocket cup set
screw, leaving about a 1/2” out of the Stealthbox.
Make sure that the socket cup end is exposed.
STEP 5: With the Stealthbox removed and wax
square still in position, use a 1/2” drill bit to drill out
the marked location.
STEP 6: Place and line up the hole, of one of the
supplied black metal plates to the 1/2” drilled hole
from STEP 5.
Place the Stealthbox into position and press down
firmly.
After hole is drilled, remove the wax square.
Use tape to temporary secure the metal plate into
position.
Please enjoy your JL Audio Stealthbox
