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.
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.

POWER RECOMMENDATION
JL Audio recommends high quality ampliers such as the JL Audio HD750/1. The diagram below shows the recommended crossover settings for the HD750/1. For a detailed description of the amplier settings, consult the
owner’s manual for the amplier. If another amplier is being used, please reference this illustration and use similar settings on that amplier.
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® amplier. Other kits
are available should you be using more than one amplier. Signal wire such as the JL Audio Premium Audio Interconnect Cables should be used to provide signal for both channels of the amplier. JL Audio
recommends using 12AWG speaker wire for subwoofers such as our XC-BCS12-25.
