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 another head
unit). 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: The speaker output is
shorted or contacts ground.
Internal Low-Pass Crossover: The
internal low-pass crossover is continuously variable from 50 Hz to 200 Hz with a
slope of 24dB/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,
waste power, and cause distortion in the audible frequencies. The
infrasonic filter can be set to OFF or ON, at 15Hz or 25Hz, with a slope of 24dB/octave. When on,
frequencies below the chosen frequency setting are cut off, resulting in increased amplifier efficiency
and better audible sound.
Band Reject Filter: This
amplifier's Band Reject filter can reduce any unwanted frequency which causes
distortion or vibrations in the vehicle compartment. It is recommended that a
signal generator or spectrum analyzer be used to determine what frequency causes
the most distortion or vibrations in order for the filter to be most effective.
The filter is continuously variable from 40 Hz to 200 Hz and can be set for -6dB
or -12dB operation.
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: Rotary
control for adjusting the output level of the amplifier.
- B.M.S. Frequency: Rotary
control for setting the center frequency of the bass boost when
the B.M.S. switch is set to "+12dB" or "Remote".
- V-Color Button: Push button
for selecting 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:
Rotary control for adjusting the crossover frequency of the
low-pass filter.
- B.R.F. Frequency: Rotary
control for adjusting the frequency of the Band Reject filter.
Right Side of Amplifier:
- B.M.S.: Switch for setting
the Bass Management System operation to Remote, Off, or +12dB.
- Band Reject: Switch for
setting the Band Reject Filter to Off, -6dB, or -12dB.
- Phase: Switch for setting
the speaker output phase to Normal or Reverse.
- Infrasonic: Switch for turning on or off the Infrasonic filter.
Inputs and Outputs
Right Side of Amplifier:
- Line In: One pair of
gold-plated RCA jacks
- Line Out: One pair of
gold-plated RCA jacks
- Ground: Screw for use with
RCA patch cables that have ground wires
- External Amp Control: Spring
clip for use with compatible Kenwood head units with B.M.S. controls.
Left Side of Amplifier:
- Fuses: Three 25-amp fuses are
inserted.
- Battery: Gold-plated screw
terminal (width: 0.557")
- Ground: Gold-plated screw
terminal (width: 0.557")
- Power Control: Gold-plated
screw terminal (width: 0.35")
- Speaker Outputs: Gold-plated
screw terminals (width: 0.35") Note: There are two sets of
terminals (+,+,--,--) on the amplifier. When connecting only one speaker to
the amp, use the center pair. When adding a second speaker, use the outer
pair. The terminals are wired internally in parallel.

Wiring
Recommendation
Wiring Recommendation:
This amplifier uses three 25-amp fuses, so its fuse rating (75-amps total)
exceeds that of typical 4 gauge wiring kits, which tend to include a 60-amp
fuse. The highest AGU fuse values carried by Crutchfield are 70 and 80 amps. To
accommodate the entire 75-amp fuse rating, the fuse included with a pre-packaged
wiring kit should be replaced with an 80-amp AGU fuse (sold separately).
