Features
CEA 2006 Compliant: The Kicker DX400.4's power and signal to
noise ratio are measured according to CEA 2006 standards (Consumer Electronics
Association). These standards allow you to accurately compare the specifications
of all CEA 2006-compliant amplifiers, even if they are different brands.
Manufacturers who adhere to the standards can display the CEA 2006 logo on their
products and packaging. The rated power output is 50 watts RMS x 4 channels into
4Ω (20 Hz-20 kHz, <1% THD+N). While the CEA 2006 S/N is 85 dB (measured
at 1 watt), the S/N at rated power is >95 dB.
Kicker Livin' Loud Certified Power: The
amplifier comes with a certificate that indicates the total maximum wattage of the
particular 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.
Protection Circuitry: The DX400.4 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 left side of the amp
illuminates red, the protection circuit has engaged and the amp will not play
until the problem is resolved.
Fail-Safe Integration Technology (FIT): To accommodate the
varying range of signal levels coming from today's factory and aftermarket
radios, the DX400.4 utilizes Fail-Safe Integration Technology (FIT), offering
isolated differential inputs for significant noise reduction, and compatibility
with virtually any factory radio.
Speaker Level Input: High level inputs can be used when the
source device doesn't have preamp level outputs. The same RCA inputs on the amp
are used for either speaker level or line level connections. When a speaker
level signal is used, speaker wire to RCA adapters are needed (item number
20609ZISL, sold separately) and the Input Level should be set to High.
Controls
Gain Control: The front and rear sections of the amp have
independent input gain controls. With the Input Level Control switch at the
appropriate setting, you can set the rotary Gain Control to match the output of
the source unit. The Gain Controls are adjusted with a flat-head screwdriver and
can be set between 0 and 11.
Input Level: The input level control is switchable; when set
to Low, the amp can accommodate a line level input signal of 125mV-5V, on High,
the amp will accept a 250mV-10V speaker level signal.
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 surge 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
Crossover: The front and rear amplifier channels have
independent crossover settings and can be set for low-pass, high-pass, or
full-range operation. The crossover points are continuously variable between 50
and 200 Hz; the crossover slope is 12 dB per octave.
KICKEQ Bass Boost: The front and rear amplifier channels
have independent bass boost controls. The bass boost circuits provide a variable
(0-12 dB) signal boost at 40 Hz.
Fader: When powering four speakers and using both the front
and rear inputs, turn the fader switch On to maintain front/rear fader control.

Warranty
Extended Warranty: Kicker will add a year to the standard two
year warranty (for a total of three years) when any matching Kicker amplifier wiring
kit is used with this amp (4 gauge minimum). Both the amp and wiring kit should be
purchased on the same order and the usual warranty limitations apply (covers
manufacturing defects, must be purchased from an authorized Kicker dealer, etc.).
