Class D Amplifier Design: The Kicker IX500.4 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 IX500.4 to have a super-small footprint for fuel savings and increased cargo
CEA 2006 Compliant: The Kicker IX500.4's power ratings are
measured according to the strict standards dictated by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even if they come from
different brands. Manufacturers who adhere to the standards can display the CEA
2006 logo on their products and packaging.
Kicker Livin' Loud Certified Power Certificate: 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.
Amplifier Rating: The Kicker IX500.4 four-Channel amplifier
is bridgeable (4-ohm), as well as 2-ohm stable in stereo.
- Four-Channel (CEA 2006 Compliant): 75 watts x 4 channel
RMS @ 4 ohms (20-20,000Hz, 1% THD)
- Four-Channel (2-ohm): 125 watts x 4 channel RMS
(20-20,000 Hz, 1% THD)
- Bridged (4-ohm): 250 watts x 2 channel RMS (20-20,000
Hz, 1% THD)
- Peak Power: 125 watts x 4 channel (500 watts total max
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
- 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.
Soft-Start Circuitry: The Kicker IX500.4 contains "soft-start"
circuitry that lessens initial shock load when powering up the amplifier, and a
muting circuit to eliminate audio distortion that might surge down the line.
Protection Circuitry: The IX500.4 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 front side of the
amp illuminates red, the protection circuit has engaged and the amp will not
play until the problem is resolved.
Stackable: The optional Kicker IXSM stacking mount (206IXSM,
sold separately) allows you to stack two Kicker IX-series amplifiers on top of
Gain: To accommodate the varying range of signal levels
coming from today's factory and aftermarket radios, the Kicker IX500.4 features
an adjustable, independent gain control (low level: 125mV-5V; high level:
250mV-10V) for the front and rear channels. This means that no matter what kind
of radio is connected to this amplifier, the appropriate gain control adjustment
can be made to ensure loud, clear, distortion-free music.
Crossover: The front and rear amplifier channels have
independent crossover settings. The internal crossovers can be set for low-pass,
high-pass, or full-range operation. The variable low-pass and/or high-pass
crossover points can be set between 50 and 200 Hz; the crossover slope is 12 dB
Bass Boost: The front and rear amplifier channels have
independent bass boost settings. The bass boost circuit provides a variable
(0-18 dB) signal boost at 40 Hz.
Fader: When powering four speakers, turn the fader switch On
to maintain front/rear fader control.
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 tighten/loosen the terminals.
Speaker Outputs: The Kicker IX500.4 is equipped with four
pair of speaker terminals. All eight speaker terminals are set-screw terminals
that will accommodate up to 8-gauge wire. The supplied allen-wrench is required
to tighten/loosen the terminals.
Note: The speaker output terminals can be used in
4-channel mode or bridged to 2-channels.
Line Level Input: The four-channel amplifier is equipped
with two pair of gold-plated RCA line level inputs.
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
136CLR2SW, sold separately) and the Input Level should be set to High.
Line Level Output: The amplifier has a pair of gold-plated
RCA line level outputs for feeding a full-range stereo signal to another
amplifier. It is the same signal that is input through the line inputs. The
amplifier's crossovers have no effect on the line level output signal.
