POWER RECOMMENDATION
JL Audio recommends high quality amplifiers such as the JL Audio XD600/lv2.
The diagram below shows the recommended crossover settings for the XD600/lv2.
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 Stealth box. JL Audio recommends using a 4 AWG power kit
such as the XD-PCS4-1 B for your Stealthbox amplifier. Other kits are
available should you be using more than one amplifier. Signal wires such as
the JL Audio Premium Audio Interconnect Cables should be used to provide a
signal for both channels of the amplifier. JL Audio recommends using 12 AWG
speaker wire for subwoofers such as our XC-BCS12-25.
