Our Product Research Team
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.
CEA 2006 Compliant: The Kicker CX300.4's power ratings are
measured under conditions approved by the Consumer Electronics
Association (CEA). These standards allow you to accurately compare the rated
power output of all CEA 2006-compliant amplifiers, even 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: The amplifier comes with
a certificate that indicates the total maximum wattage 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
Auto Turn-on: The amp offers two automatic turn-on modes:
- +12V: connect a wire from the remote
turn-on lead from your source unit to the REM terminal on
the amplifier; this is the preferred turn-on method
- DC Offset: turns the amp on when a
6-volt DC offset is detected at the high-level speaker
inputs when the source unit is turned on
Vertical Mounting: The amp can be mounted vertically using
the included brackets. The vertical dimensions are approximately:
- Width: 13-1/4"
- Height: 7-1/4"
- Depth: 2-3/8"
Signal to Noise Ratio: The S/N under CEA-2006 compliant
conditions (1 watt output) is 75 dBA. The S/N at rated power is 95 dB.
Input Level Switch: Set the input level switch to Lo when
using preamp level input signals and Hi when using speaker level input signals.
Fader: When your source unit has discrete front and rear
outputs, set the fader switch to on. Turn the fader switch off to send a single
stereo input to both the front and rear amps.
Gain: The front and rear sections of the amplifier (Amp1
and Amp2) have independent rotary gain controls, continuously variable from
125 mV to 5 V when the Input Level switch is set to Low and 250 mV to 10 V
when the Input Level switch is set to High.
Crossover: The front and rear sections of the amplifier also
have independent crossover circuits:
- Mode: three position switch; Off (crossover bypassed),
Hi (high-pass), an Lo (low-pass)
- Frequency: continuously
variable from 50 to 200 Hz; the slope is 12 dB per octave
Bass Boost: The bass boost circuit is continuously variable
from 0 to +12 dB and centered at 40 Hz. The front and rear amps have separate bass
Left Side of Amplifier:
- +12V (power): terminal strip; accepts
spade connectors up to 0.5" wide
- REM (remote turn-on): terminal strip;
accepts spade connectors up to 0.325" wide
- GND (ground): terminal strip; accepts
spade connectors up to 0.5" wide
- Speaker Outputs: terminal strip with four
pair of outputs; accepts spade connectors up to 0.325" wide
Note: The Amplifier is not equipped with an internal fuse.
An external 60-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 60-amps, the original should be replaced with
a 60-amp fuse.
Right Side of Amplifier:
- RCA Inputs: two pair of stereo
RCA inputs (Amp1 and Amp2); also used for speaker
level input (up to two of item number
206KiSL needed, sold separately)
Amp Wiring Kit: Kicker recommends using an 8-gauge wiring kit
with this amplifier.
