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.

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 (WARRANTYVOID):
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 dr
astically
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.
