Owner's of the JL Audio Portable Speaker Mobile Subwoofer gave it a score of 0 out of 5. Here's how the scores stacked up:
Infrasonic Filter:
Turn “O” for Sealed Enclosure.
Turn “On” for Ported Enclosure and
set the knob to “25” Hz.
Bass EQ:
Generally not necessary in W7 applications (we recommend defeating it by
switching the “Bass EQ” switch to “O”). May be used with Remote Bass
Control to provide some user controllable broad bass boost. When used in this
manner, set “Q” to “1.1”, set “Center Freq.” to “45” Hz, “Boost” is defeated by
connection of Remote Bass Control.
Input Sensitivity Controls:
Proper adjustment of these controls is critical!
For virtually all aftermarket head units,
set “Input Voltage” to “Low”.
See “Input Sensitivity Setting Guide”
on pg. 14 for precise setting instructions.
Dual Mono Speaker
Output Connections:
Connect wire directly to “+”
and “–” “Subwoofer Output”
connections and to the W7.
Remote Bass Port:
Permits connection of an
optional remote bass boost
controller (RBC-1), giving you
control over the boost of the
parametric EQ from the front
of the vehicle. The RBC-1
controller is sold separately.
Amp Low-Pass Filter:
Set “Mode/Slope” switch to “24dB”.
Set “Filter Freq. (Hz)” knob to “85”.
Lower settings are likely to result in a
poor transition between the upper
response of the W7 and the lower
response of the mid-bass speakers.
Amplier Input:
Connect RCA-type
cables from the head
unit (or processor) to
these two jacks.
Use both jacks
(with a Y-adapter
if necessary).
Output Polarity:
Carefully listen to the sub-bass to
mid-bass transition with music that
has strong mid-bass content. Select
the switch position which gives the
smoothest, most natural mid-bass
response. If using multiple 1000/1’s
on multiple subwoofers, make sure
this switch is set to the same position
on all ampliers.
JL Audio 1000/1v2:
These settings are intended
as a “baseline” for tuning
your system. Depending
on your vehicle and your
preferences, some variation in
the crossover and bass control
settings may be necessary
for optimum performance.
RECOMMENDED CONTINUOUS RMS POWER RANGE FOR ONE SUBWOOFER DRIVER:
