CEA 2006 Compliant: The
ZX750.1's power and signal to noise ratio ratings are measured according to the strict standards dictated
by the Consumer Electronics Association (CEA). These standards allow you to
accurately compare the output ratings 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. The
manual lists two signal to noise ratios:
- CEA 2006 compliant: 68 dB
- At rated Power: 95 dB
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.
Dual Input Sensitivity Differential RCA Inputs: The ZX750.1 has one
pair of RCA inputs which will receive either high or low level signals from your
car stereo. The unit has an input level switch that allows you to select a low-
or high-level input. A low-level signal from the stereo's preamp output is
recommended. If the stereo lacks preamp outputs, you can use the unit's
speaker-level outputs by attaching RCA plugs onto the speaker wire, and set the
input level switch to "HI".
Auto Turn-on Selection: The ZX-series offers three different automatic
turn-on modes that can be selected on the end panel. You can select from the
- Remote Turn-on: You can connect an 18-gauge 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 Turn-on: The DC offset mode detects a 6-volt surge from
the high-level speaker outputs when the source unit is turned on. If remote
turn-on is not an option, this is the next best choice.
- Signal Sense Turn-on: This method detects the incoming audio
signal from your source unit and automatically turns on the amp. This method
will not work properly if the input gain control is not set properly.
Protection Circuitry: The ZX750.1's protection circuitry guards against accidents
and undesired operation. The amp is protected by thermal protection, voltage
protection, and short circuit protection. The Power LED on the left side of the amp glows green
and the power indicator on top of the amp glows red when the amplifier is
connected correctly and the protection has not been engaged. If the red Protection LED
illuminates, the amp's protection circuit has been engaged and the amplifier is in protect mode until
the problem is resolved.
Optional ZX-Series End Caps: You can add the optional ZX-series
amplifier end caps (2068ZXEC,
sold separately) to this amplifier. These plastic end caps cover
the wire terminals and controls located on the ends of the amp for a clean
installation. When installed, the end caps add approximately 2-5/8" to the
overall width of the amplifier.
Filter: The internal low-pass filter can be adjusted from 50 to 200 Hz, and
has a slope of 24dB per octave.
Filter: The subsonic filter allows the amplifier to block ultra-low
frequencies that your subs can't reproduce, improving the efficiency of your
speaker system. The filter is fixed at 25 Hz, and has a slope of 24dB per
KICKEQ Bass Boost: The ZX750.1's KICKEQ bass boost circuit provides up to 18dB signal boost at 40Hz.
The bass boost circuit is continually adjustable from 0 to 18dB.
Bass Level Control: The Remote Bass Level Control lets you adjust the output
level of the amplifier from anywhere in the vehicle. When attached to the
mounting bracket, the Remote Bass Level Control has the following dimensions:
W=2.207", H=1.175", D=2.133" (including the knob). A 19' 9" cable
is included for routing the remote bass level control signal to the front of the
Left Side of Amplifier:

- Fuse: two 40-amp fuses
Right Side of Amplifier:
- Auto Turn-on Selection: 3-way switch (+12V, DC Offset, Audio)
- Input Level Switch: 2-way push button (out=Low, in=High)
- Speaker Outputs:
gold-plated set screw terminals (accepts up to 8 gauge wire)
- RCA Input: gold-plated RCA
- RCA Output: gold-plated
RCA line output jacks
- Remote Bass: RJ14 jack for use
with supplied Remote Bass Level Control
Amp Wiring Kit:
Kicker recommends using a 4-gauge amp wiring kit with this amplifier.
