INSTALLATION GUIDE
for the
SB-N-ALT/10W3v3
SKU# 94447
2007+
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

STEP 6
Remove the indicated screw so that the inner fender liner
can be pulled down. Make sure that there is clearance where
you will be drilling through the inner fender to mount the
Stealthbox®
STEP 5
Place the Stealthbox® in location, keeping the bottom of
the Stealthbox® parallel with the floor of the trunk. Press
the head of the bolt installed in STEP 4 into the 3” x 3” Wax
Square that was installed in STEP 2. The head of the bolt
should make a depression in the Wax Square, if it does not,
back out the bolt and repeat until it does. After the 3” x 3”
Wax Square has been marked, remove the bolt from the
enclosure.
Now is an excellent time to test the Stealthbox® and
the amplifier to ensure that everything is working as
it should.
STEP 4
At the front of the enclosure thread the 3/8-16 x 1-1/4” Hex
Head Bolt all the way into the enclosure so that only the
head of the bolt is exposed.

of the trunk opening that goes down through the floor as

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
