Subwoofers

o w n e r ’ s m a n u a l

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.

If you decide to build one of these enclosures yourself, you must have the construction of the box

inspected and approved by your authorized JL Audio dealer in order for the 1 year limited warranty to

be valid. Please read the warranty information carefully.
