Inputs and Outputs Notes
Class D Mono Amplifier:
The Class D design of the
Kicker KX400.1 amplifier allows it to deliver massive power without big current
draw. Class D amplifiers are very efficient, converting voltage to output power
without generating a lot of heat.
EndKaps: The amplifier features
two removable, cast aluminum EndKaps that are mounted to each end of the
amplifier. These EndKaps protect and hide all of the wiring connections to the
amplifier, and must be removed before the amp is mounted. The EndKaps can be prepped and painted any custom color you choose.
They are mounted to the amp with 4 Allen-head screws (3mm Allen wrench
Top-mounted Controls: The
features three rotary controls on the top panel: input gain control, bass boost
control and crossover frequency control. These controls can be easily accessed,
even with the EndKaps installed.
Variable Low-Pass Filter: The
amp is equipped with a full-time variable low-pass filter which prevents
unwanted high frequencies from reaching your woofers. The cutoff frequency is continuously variable from 50 to 200Hz
with a 12dB/octave slope.
Subsonic Filter: The amplifier
features a 25Hz subsonic filter which eliminates the very low inaudible
frequencies which can damage speakers and rob power. The subsonic filter has a
12dB/octave slope, and can be turned on or off with a switch on the side of the
KickBass Bass Boost: The
KickBass bass boost circuit provides up to 18dB signal boost at 40Hz.
Remote Bass Level Control:
The dash-mounted remote unit allows you to adjust the output level of the
amplifier. A 19.25' cable is included to allow you to control a trunk-mounted
amp from the front of the vehicle. Dimensions: W=2.2", H=1.186", D=1.736" (2.114"
including the knob).
Strapping: Two KX400.1 amplifiers can be connected
or "strapped" together to drive one woofer. The amps are connected together with
the supplied strapping cables ("mono-mini" cables), and output double their
rated power (in this case, 400 watts RMS each). The speaker's impedance for this
application should be 4 ohms. Note: You can only strap two of the same
model amps together.
Protection Circuitry: The SORT (Short circuit, Over-voltage,
Reverse polarity, Thermal) protection circuitry guards against
accidents and undesired operation. If the red Protection LED illuminates, SORT
has been engaged and the amplifier is in protect mode until the problem is
Kicker "Living Loud"
Certified Power Certificate: The
amplifier comes with a certificate that indicates the total maximum wattage
of your specific amplifier, along with the model number, serial number, tested
date, and whether the amplifier passed the total harmonic distortion,
signal-to-noise ratio, and protection circuit tests. In most cases, the
amplifier's certified power output surpasses the rated power.
and Outputs Notes
The KX400.1 uses custom-tooled, gold-plated connectors to assure maximum
power transfer and damping.
Set-Screw Terminals: The power
and ground set-screw terminals can accept up to 4-gauge bare wire. The speaker
output set-screw terminals can accept up to 8-gauge bare wire. The remote
turn-on set-screw terminal can accept up to 12-gauge wire. A 3mm Allen wrench is
provided to tighten/loosen the set screws.
Inputs: High-level input connections
are included to allow use with a factory radio or other receiver without RCA preamp outputs. A 12" speaker-level input harness with a 4-pin Molex plug on
one end is provided. The receiver's speaker wires will need to be spliced to the
bare wires on the speaker-level input harness.
Line Outputs: The
PAST (Pre-Amp Signal Transfer) line outputs allow you to pass a full-range
preamp-level signal from this amplifier to another amplifier. This eliminates
the need to use RCA splitter cords to distribute signals to two amplifiers.
Note: A signal is output from the PAST Line Out jacks regardless of whether
the line-level or speaker-level inputs are used.
Output (at 1.5% THD+N):
- Input Voltage at 14.4 Volts:
- 200 watts RMS into 4 ohms
- 400 watts RMS into 2 ohms
- Input Voltage at 12.5
- 170 watts RMS into 4 ohms
- 240 watts RMS into 2 ohms
- Without EndKaps:
Width=9.375", Height=2.332", Depth=9.513"
- With EndKaps: Width=12.75",
