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.

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.

This warranty is not transferable and applies only to the original purchaser 

of the product from an authorized JL AUDIO dealer.  Warranty is voided if 
the factory-applied product serial number is removed or defaced.

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.

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).

RECOMMENDED CONTINUOUS (RMS) POWER RANGE FOR ONE SUBWOOFER DRIVER:

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.

Automotive Subwoofer Components

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. This power level is 

 

lower than the woofer’s continuous power rating 
(as published in its specifications), but you will still 
be taking advantage of the woofer’s, low-distortion 
performance range without undue risk of failure.

DARK GRAY (MAXIMUM):

 

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 
subwoofer driver is designed to operate safely 
up to this power range, but not beyond. 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.

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.
