Congratulations on your purchase of a JL Audio subwoofer component. Your JL Audio subwoofer
is a precision loudspeaker which has been engineered to produce the highest quality sub-bass
performance in your vehicle. Authorized JL Audio dealers have extensive technical information
for many different applications of your new speaker. They also have the knowledge, skills and tools
to build a high-quality enclosure that will maximize the performance of your speaker. We highly
recommend that you have your enclosure built by an authorized JL Audio dealer.
Inside you will find specifications and two recommended enclosures for your speaker; one is a
sealed enclosure, the other is a ported design. Both types of enclosures will give you excellent sound
quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely
tight, but the ported enclosure will produce 3dB more output at the same power if you have the
extra space to work with.
