If you choose to perform the installation yourself, it is absolutely vital
that the Stealthbox
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.
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. If you prefer to perform your own installation, please read
this installation guide completely before beginning the process.

POWER RECOMMENDATION
JL Audio recommends high quality ampliers such as the JL Audio XD300/1v2. The diagram below shows the recommended crossover settings for the XD300/1v2 For a detailed description of the
amplier settings, consult the owner’s manual for the amplier. If another amplier is being used, please reference this illustration and use similar settings on that amplier.
CONNECTIONS
Using quality power, signal, and speaker wire is essential in ensuring the performance of your Stealthbox®. JL Audio recommends using a 4 AWG power kit such as the XD-PCS4-1B for your
Stealthbox® amplier. Other kits are available should you be using more than one amplier. Signal wire such as the JL Audio Premium Audio Interconnect Cables should be used to provide signal for
both channels of the amplier. JL Audio recommends using 12AWG speaker wire for subwoofers such as our XC-BCS12-25.
