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.

JL AUDIO LIMITED WARRANTY (USA)

Automotive Subwoofer Components

JL AUDIO warrants this speaker to be free of defects in materials and workmanship for a period of one (1) year from the original date of purchase, contingent

upon installation being performed or approved by an authorized JL AUDIO dealer, in writing, on the original sales receipt. If the preceding condition is not met,

the warranty term is limited to ninety (90) days from the original purchase date.

This warranty is not transferrable and applies only to the original purchaser of the product from an authorized JL AUDIO dealer. Should service be necessary

under this warranty for any reason due to manufacturing defect or malfunction, JL AUDIO will, at its discretion, repair or replace the defective product with new or

remanufactured product at no charge.

Damage caused by the following is not covered under warranty: accident, misuse, abuse, product modification or neglect, failure to follow installation instructions,

unauthorized repair attempts, misrepresentations by the seller. This warranty does not cover incidental or consequential damages and does not cover the cost of

removing or reinstalling the unit(s). Cosmetic damage due to accident or normal wear and tear is not covered under warranty.

Any applicable implied warranties are limited in duration to the period of the express warranty as provided herein beginning with the date of the

original purchase at retail, and no warranties, whether express or implied, shall apply to this product thereafter. Some states do not allow limitations on implied warranties,

therefore these exclusions may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.

If you need service on your JL AUDIO product:

All warranty returns should be sent to JL AUDIO freight prepaid through an authorized JL AUDIO dealer and must be accompanied by proof of

purchase (a copy of the original sales receipt.) Direct returns from consumers or non-authorized dealers will be refused unless specifically authorized by JL AUDIO

with a valid return authorization number. Warranty expiration on products returned without proof of purchase will be determined from the manufacturing date

code. Coverage may be invalidated as this date is previous to purchase date. Return only defective components. Non-defective items received will be returned freight-

collect. Customer is responsible for shipping charges and insurance in sending the product to JL AUDIO. Freight damage on returns is not covered under warranty.

Always include proof of purchase (sales receipt).

MEDIUM GRAY (MINIMUM):

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.

LIGHT GRAY (OPTIMUM):

This zone represents the best compromise

between long-term reliability, high-output and

low-distortion performance and is centered

on each woofer's continuous power rating (as

published in its specifications). In this zone, you

will be taking full advantage of the woofer's

optimum, low-distortion performance range

without undue risk of failure.

DARK GRAY (MAXIMUM):

In this zone, low-distortion output and

long-term reliability will be compromised

(especially by an aggressive user). Slightly

more SPL will be gained by pushing the

power into this zone, but typically not more

than 2dB, compared to the light gray zone.

The closer you are to the black zone, the

higher the likelihood of driver failure.

Operate with caution.

BLACK (WARRANTY VOID):

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.

JL Audio offers an extensive line of high-performance subwoofer drivers to fit a wide variety of enclosure and power applications. When designing systems with our

drivers, it is very important to achieve a good power match between the subwoofer amplifier and the subwoofer driver's capabilities. The power levels listed in the

above chart represent continuous (RMS) amplifier power per woofer and assume that the user will regularly make full use of that power without drastically

overdriving the amplifier(s). Make sure you factor system impedance and the total number of subwoofers into your calculations. Adhering to these power

recommendations will result in systems that are both reliable and enjoyable.
