Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Bass Management System (B.M.S.): This
feature allows precise tailoring of bass frequencies, either remotely, with a
compatible Kenwood eXcelon head unit, or manually, when used with a head unit
without B.M.S. controls. When connected to a Kenwood eXcelon head unit (1999 or later models with
an "External Control" wire attached), the B.M.S. controls can select
0dB, 6dB, 12dB of bass boost. The bass boost center frequency is variable
between 40 Hz and 100 Hz. Newer head units with B.M.S. control can also select
18dB of bass boost and "frequency offset." The frequency offset
control can switch between "Normal" (as set by the variable control)
or "Low" (20-30% lower). The manual B.M.S. setting provides a 12dB of
bass boost at the frequency selected.
Variable-Color Indicator: The
status indicator on the top of the amplifier is a variable-color LED that lights in one of
7 selectable colors or constantly changing colors to tell you the amplifier's
operating status. Under normal operation, the LED glows constantly. The LED will blink in a certain color based on the
amp's status or
if the amp has malfunctioned and has gone into protection mode. The blinking
color codes include:
- Blue: B.M.S. is activated.
- Yellow: The input power is
less than 11 Volts.
- Purple: A DC signal is being
sent to the speaker output.
- Red: The unit is
overheating.
- Green: A speaker cable is
shorted or making contact with vehicle ground.
Internal Crossover: The
internal crossover is selectable for high-pass, full range, or low-pass
operation, and is variable from 50 Hz to 200 Hz. The slope of the high-pass filter is
12dB/octave and the low-pass filter is 18dB/octave.
Infrasonic Filter: This
amplifier features an infrasonic filter, which can cut off inaudible
frequencies. Extremely low frequencies can be stressful to an amplifier or loudspeakers, and can cause distortion in the audible frequencies. The
infrasonic filter can be set to OFF or ON, with a slope of 24dB/octave. When on,
frequencies below 15 Hz are cut off, resulting in increased amplifier efficiency
and better audible sound.
Fan Cooled: This amplifier has
an internal cooling fan. There are air inlets on the top of the amp; air exhaust
outlets are on the ends of the amp.
Terminal Covers: The amplifier
comes with two black plastic terminal covers designed to be mounted on each end
of the amp to hide the wires and give it a cleaner look. Mounting hardware is
included.
Controls
Top of Amplifier (under removable
cover):
- Input Sensitivity Control: Rotary
control that allows you to adjust the output level of the amplifier.
- B.M.S. Frequency Control: Rotary
control that allows you to set the center frequency of the bass boost when
the B.M.S. switch is set to "+12dB" or "Remote"
- V-Color Button Control: Selects the
"ON" color for the LED indicator. Each time the button is pressed
it selects one of 7 fixed colors or the variable color indicator.
- LPF Frequency Control:
Rotary control that allows you to adjust the crossover frequency of the
low-pass filter.
- HPF Frequency Control: Rotary
control that allows you to adjust the crossover frequency of the high-pass
filter.
Right Side of Amplifier:
- Infrasonic Switch: This switch
allows you to turn on or off the Infrasonic filter.
- B.M.S. Switch: This switch allows
you to set B.M.S. operation to Remote, Off, or +12dB.
- Filter Switch: This switch allows
you to select HPF (High Pass filter), Off, or LPF (Low Pass filter)
- Operation Switch: This switch
allows you to select Stereo or Mono operation. Note: When the
amplifier is being used in the bridged mode, the mono operation should be
selected. During mono operation, only the left channel input signal is
amplified. There is no amplification of the right channel input.
