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.
4-Channel Amp: The front and rear sections of the amplifier
(labeled Amp1 and Amp2) have independent gain, crossover, and bass boost controls.
Gain: The rotary gain controls are continuously variable from
125 mV to 5 V when the Input Sensitivity switch is set to Low and 250 mV to 10 V
when the Input Sensitivity switch is set to High.
Crossovers: The front and rear crossovers can be independently
set to high-pass, low-pass, or turned off (full range). The crossover points are
continuously variable from 50 to 200 Hz and the slope is 12dB per octave.
Auto Turn-on Switch: The amp offers three automatic turn-on
modes; select from:
- +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
- Audio: detects the incoming audio
signal from your source unit and automatically turns the
amp on; will not work if the input gain control is not
Bass Boost: The bass boost circuits provide up to 18dB boost
Fader: When powering four speakers and using both the front
and rear inputs, turn the fader switch on. To supply all four channels from only
one input, turn the fader switch off.
ZXRC Remote Bass Control: When the Amp2 section crossover is
set to low-pass, an optional wired remote bass control (item number 20610ZXRC,
sold separately) can be used to remotely adjust the bass level output.
Left Side of Amplifier:
- +12V (power): set screw
- REM (remote turn-on): set
- GND (ground): set screw
- Fuse: two 20-amp ATO fuses
Right Side of Amplifier:
- Speaker Outputs: four pair of set screw
- RCA Input: two pair of stereo RCA input jacks; also
used for speaker level input (item number
needed, sold separately)
Amp Wiring Kit: Kicker recommends using a 4-gauge wiring
kit with this amplifier.
