JL AUDIO Jeep Gladiator JT Installation Guide
Important!
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:
- The sub-bass performance will suffer due to the movement of the enclosure caused by the force exerted by the woofer(s).
- 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 reassembleyour 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 amplifiers such as the JL Audio XD600/1v2. The diagram below shows the recommended crossover settings for the XD600/1v2. For a detailed description of the amplifier settings, consult the owner’s manual for the amplifier. If another amplifier is being used, please reference this illustration and use similar settings on that amplifier.
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® 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 to provide signal for both channels of the amplifier. JL Audio recommends using 12 AWG speaker wire for subwoofers such as our XC-BCS12-25.
