SB-GM-SLVCC2/12TW3 INSTR_SKU# 011370
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 ampliers 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
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.
