JL AUDIO 12W3 3
• 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.
• When using two subwoofers in a common
enclosure simply double the required volume and,
in the case of a ported enclosure, use two times
the recommended port(s). Likewise, when using
three subwoofers in a common enclosure simply
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
bi-amplified system using high-quality satellite
speakers and a high-quality amplifier. We do not
recommend the use of this subwoofer with a
passive crossover (coil), as this type of device will
adversely affect performance.

Prolonged exposure to sound
pressure levels in excess of 100dB
can cause permanent hearing loss.
This high-performance speaker can
exceed this level. Please exercise
restraint in its operation in order
to preserve your ability to enjoy
its fidelity.
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.
CAUTION
All specifications are subject to change without notice.
