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.
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).

Automotive Subwoofer Components
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 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.
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.
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.
