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.

! ! CAUTION ! !

Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance

speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.

When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend

bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for

reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important

in a hatchback, station wagon, sports utility vehicle, or van.

• The enclosure recommendations listed are external

dimensions which assume the use of 3/4" (19mm)

thick material. If you are using 5/8" (16mm) thick

material, subtract from each dimension. 1/4" (6.5mm)

Do not use any material with a thickness of less than

5/8" (16mm) as this may compromise the rigidity of

the enclosure.

• All enclosure volumes listed are net internal volumes!

Box volume displacement, port displacement and

brace displacement must be added to obtain the final

gross internal volume. All enclosure dimensions listed

have already taken this into account.

• When using subwoofers in a common two

enclosure simply the required volume and, double

in the case of a ported enclosure, use two times the

recommended port(s).

• We recommend the use of this speaker in a bi-

amplified system using high-quality satellite speakers

and amplifiers. We do not recommend the use of

this subwoofer with a passive crossover (coil), as this

type of device will adversely affect performance.
