owner’s manual
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.
