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
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
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.

RECOMMENDED ENCLOSURES
Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This
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 above are external dimensions which assume the use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. 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 above are net internal volumes! Driver displacement, port
displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into acount.

triple the required volume and, in the case of a ported enclosure, use three times the recommended port(s).
???We recommend the use of this speaker in a

From a reliability standpoint, this zone represents a very comfortable operating power range for each driver. This level of power will not stress the woofer but will not extract all of its performance potential, either.
Use of less than the minimum power level will not damage the woofer, but may result in unsatisfactory performance.
This zone represents the best compromise between
In this zone,
We do not recommend operating woofers at this level of power. In this zone, there is a very high probability that the driver will fail due to excessive heat and/or mechanical stress.
Subwoofer drivers operated at these levels of power are NOT covered under warranty.
