Sheet SKU#011158 Revision 9/17/2004 Page 1
for the
SB-H-CIVCPE/12W3v2
(Fits 2001-2003 Honda Civic Coupe,
2-door)
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(s) and
2) A loose enclosure presents a serious
safety hazard in the event of a collision
or sudden deceleration.
Please enjoy your JL Audio Stealthbox
responsibly.
STEP 1:
Remove the factory cargo net, net
hooks and the flooring.
STEP 2:
Cut the passenger’s side wood floor-
boards ear. Do this outside of the vehicle.
Using a straight edge and marking a line will
help in cutting a straight line.
STEP 3:
Only remove this cargo net hook.
This is on the passenger side of the trunk.
*In the next two steps ,you need to plot
two marked locations from measurements. This is to find the proper location of the placement of the supplied
wax square.*
STEP 4:
Measuring 5.0” (127mm) from the
floor, up to the mark from STEP 4.Mark
location.
STEP 5:
Measuring 8” (203.22mm) from the
rear of the back rear to the trunk opening,
mark location.
STEP 6:
This placement of the wax square is
not going to allow for good adhesion. Using a
heavy duty style tape will help the wax square
to stay into place.
*You do not want the wax square to
move, when placing the Stealthbox
into place, in STEP 9.*

STEP 7:

square, between the second and the third
indentation starting from the front of the vehicle(shown with arrows in above
picture).

should be flush with the edge of the factory
trunk linear.

STEP 8: Place the pair of supplied socket cup set
screws into the Stealthbox. Leaving about 1/4”
exposed.
The insert can be located by flipping the Stealthbox
upside down.
STEP 12: Replace the flooring, that was removed
in STEP 1. Using a utility knife, cut a slit that is lined
up with this location’s mounting hole.This is to allow
the socket cup set screw to pass through the carpeting to the mounting hole.
STEP 13: Replace the factory cargo net and
hooks, that were removed in STEP 1.
Run speaker wire to the Stealthbox location and
attach to the terminal, on the back of the
Stealthbox.
*Double check the woofer for proper opera-
tion.*
STEP 9: Place the Stealthbox into place and
press firmly. When pulled away, the wax squares
should have the socket sup set screw markings. If
not you need to back out the set screws, for proper
marking.
The upper wax square didn’t move? You did tape it,
right?
STEP 10: Pull the Stealthbox out of location.
*CAUTION*
Before drilling, make sure that you are not going to

lines, electrical wiring or anything else that might
cause a reduction in your weekly pay. Always wear
