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.
