Class D Amplifier Design: The Kicker KX200.2 is a full-range
Class D amplifier, which uses digital switching to amplify audio signals. This
design results in high efficiency and less heat. The Class D design also allows
the KX200.2 to have a small footprint for increased cargo space.
CEA-2006 Compliant: CEA-2006 is a system of testing and
measurement methods for mobile audio amplifiers. This voluntary standard advocates
a uniform method for measuring an amplifier's RMS power output and signal-to-noise
ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and
the RMS power output is measured into a 4Ω load, with 1% or less Total Harmonic
Distortion plus noise (THD+N), and over a frequency range of 20 Hz to 20 kHz, when
applicable. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA)
at a reference of 1 watt into 4Ω. CEA-2006 allows consumers to compare car
amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Kicker
KX200.2 is rated at 50 Watts RMS x 2 channels with a 75 dBA signal to noise ratio.
Specifications: The manual also lists these non CEA-2006
- 2Ω: 100 watts x 2-channels
(no more than 1% THD+N, 14.4 volts)
- Bridged: 200 watts x
1-channels (into 4Ω with no more than 1% THD,
- Signal to Noise Ratio: 95 dB (at
Kicker Livin' Loud Certified Power Certificate: The amplifier
comes with a certificate that indicates the total maximum RMS power output of the
particular amplifier, along with the model number, serial number, and whether the
amplifier passed the total harmonic distortion, signal-to-noise ratio, and protection
Stereo and Mono Simultaneously (SAMS): You can drive a mono
subwoofer and stereo speakers at the same time with this amplifier. Passive
crossovers are required on the speaker outputs (high pass for the stereo
speakers and low pass for the subwoofer). The minimum impedance for SAMS
operation is 2Ω per channel for the stereo speakers and 4Ω for
the subwoofer (bridged mono).
Auto Turn-On: The Auto Turn-On switch offers three options:
- +12 V: The amp turns on when +12 volts
is applied to the remote terminal.
- DC Offset: The amp turns on when a 6 volt
offset is detected on the signal inputs (from a speaker-level
source); in this mode the amp's remote terminal acts as a +12
volt output to turn on another component.
- Audio: The amp turns on when an incoming
audio signal is detected; in this mode the amp's remote terminal
acts as a +12 volt output to turn on another component.
Protection Circuitry: The KX200.2 has protection circuitry
that will turn the amp off in the event of overheating, over voltage (power input),
under voltage (power input), short circuit (speaker output), and over current
(speaker output). If the Protection LED on the front side of the amp illuminates
red, the protection circuit has engaged and the amp will not play until the problem
Gain: To accommodate the varying range of signal levels
coming from today's factory and aftermarket radios, the Kicker KX200.2 features
an adjustable gain control (low level: 125mV-5V, high level: 250mV-10V). The
rotary control is labeled from 0 to 11.
Crossover: The amplifier has a four position crossover switch
that lets you select Low-pass, High-pass, Band-pass, or Off (for full-range operation).
The crossover's high-pass and low-pass cutoff frequencies are set independently;
the high-pass is continuously variable from 10 Hz to 500 Hz and the low-pass is
continuously variable from 40 Hz to 500 Hz or from 400 Hz to 5 kHz, depending on
the setting of the low-pass range switch (1x or 10x). When using the band-pass
setting, both the high-pass and low-pass crossovers are active. The slope is 24
dB per octave.
KickEQ: The amplifier's KickEQ bass boost circuit provides
a variable (0-18 dB) signal boost, centered at 40 Hz.
Power Connections: The power and ground connections are
set-screw terminals that will accommodate up to 4-gauge wire. The remote turn-on
set-screw terminal will accept up to 8-gauge wire. The included Allen-wrench is
required to loosen/tighten the terminals.
Note: The Amplifier is not equipped
with an internal fuse. An external 40-amp fuse (not
included) must be installed on the power wire. If the
system has only this amp and a wiring kit is used that
includes a fuse with a value other than 40-amps, the
original should be replaced with a 40-amp fuse.
Speaker Outputs: The Kicker KX200.2 is equipped with set-screw
terminals for two speakers. The terminals will accommodate up to 8-gauge wire and
are loosened/tightened with the included Allen-wrench.
Note: The speaker output terminals can
be used in 2-channel mode or bridged to mono.
Dual Input Sensitivity Inputs: The KX series amplifiers have
dual input sensitivity differential RCA inputs, which will accept either speaker-level
(high) or RCA (low) signals from your car's head unit. A high-level signal can be run
from the head unit's speaker outputs to the stereo RCA input of the amplifier using
a Speaker Wire to RCA adapter
sold separately). The Input Level Switch on the amp should be set to high when using
a speaker-level input, and low when using an RCA line-level input.
Line Level Output: The amplifier has a pair of RCA line level
outputs for feeding another amplifier. This is the same signal that is present at
the amp's inputs. Either input method (speaker-level or RCA) will provide a low-level
output signal to the RCA outputs. The amplifier's crossovers have no effect on the
line level output signal, however, if you input a filtered signal from the head unit,
the amp's low-level output will also be filtered.
