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.

J2 1000.1 or J2 500.1. The diagram below shows the recommended crossover, infrasonic filter and equalizer

detailed information about installing and tuning your amplifier.

C O N N E C T I O N S

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® amplifier, other
kits are available should you be using more than one amplifier. Signal wire such as the JL Audio Premium
Audio Interconnect Cables should be used that will provide signal for both channels of the amplifier. JL Audio
recommends using 12AWG speaker wire for subwoofers such as our XD-BCS12-25.
