Remote Level Control
Requires HD-RLC controller
(sold separately). Multiple
amplifiers can be controlled
with one controller by
adding standard phone
cable splitter (not included).
This is a true subwoofer level
control, not a “bass boost”.
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.
JL Audio XD600/1v2:
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.
Filter Mode & Slope:
Set “LP Filter 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 W7AE and
the lower response of the
mid-bass speakers.
Turn-On Mode:
All XDv2 models offer the
convenience of automatic
turn-on (signal or DC-offset
sensing), and a dual-
range input section that
can accept a wide range
of input signals, from
line-level to high-power,
speaker level signals.
