46CXA18001t

Subsonic Filter: The amplifier features a non-defeatable 25Hz Subsonic Filter with a 24dB/octave slope. The Subsonic Filter rolls off extremely low frequencies that can't be cleanly reproduced by the amplifier and subwoofers. This reduces distortion and helps the amp run more efficiently.

Mounting: The efficient Class-D Kicker CX Series amplifiers can be mounted vertically, if desired, with the included mounting brackets.

Auto Turn-on: The amplifier has two methods of turning on: +12V and DC Offset. The preferred method is to run an 18-gauge wire from the remote turn-on lead of the source unit to the Remote (REM) terminal on the amp. When a +12V signal is detected on the wire, the amplifier will turn on. If your source unit lacks a remote turn-on lead (a factory head unit, for example), you can choose to turn on the amplifier via the DC Offset method. When a DC offset is detected (>2.5 volts) on the speaker-level inputs, the amplifier automatically turns on.

Vehicle Integration: The CXA1800.1 amplifier features Kicker's FIT 2+ (Fail-safe Integration Technology 2 PLUS) technology, providing near-universal compatibility with stock and aftermarket radios. Start/Stop vehicle compatibility and the ability to accept factory input signals as high as 40-volts make the CXA1800.1 compatible with almost every vehicle and factory or aftermarket radio.

Wire Connections: The CXA1800.1 has set screw terminals for power, ground, and turn-on (REM). The power and ground terminals will accept up to 4-gauge wire (recommended), and the turn-on lead will accept up to 8-gauge (18-gauge recommended). The set screws are loosened/tightened with the supplied 3mm Allen wrench. The speaker outputs are slotted, screw-down terminals, which will accommodate bare wire or spade connectors. The speaker slots are 0.335" wide.

External Fuse: The amplifier does not include a built-in fuse, therefore an external fuse should be placed on the power wire, within 18" of the battery. It is recommended that a 1/0-gauge amplifier wiring kit and a 150-amp external fuse be used when installing the amplifier.

Input Signal: The CXA1800.1 accepts either high (speaker-level) or low (line-level) input signals on the RCA inputs, selectable using the input level switch on the end of the amp. When using a speaker-level input signal, add the optional Kicker KiSL speaker-level to RCA adapter. The input sensitivity is 125mV-5V (low) or 1V-40V (high).

Preamp Output: Using either a speaker-level or line-level input feeds the stereo RCA output, which passes the audio signal to another amplifier or component. This allows you to daisy-chain another amplifier without having to run RCA cables from the head unit to the second amp.

Optional Wired Remote: The optional CXARC remote bass level control can be added to remotely control the output level of the amplifier. The CXARC's control knob can be mounted near the driver's seat, and the control's cable extended to the amplifier location.

Certified Power: Each amplifier is tested when it comes off of the assembly line. Tests are run for Total Harmonic Distortion, Signal-to-Noise Ratio, Protection Circuit, and Total Power Output. A Certified Power certificate with model and serial number is included with each amp with the measured power output figure, and a pass/fail grade for the other tests.

• Power Output: 900 watts RMS x 1 into 4Ω

Controls:

• Input Level: 2-position switch; select high (speaker-level) or low (line-level)
• Input Gain Control: rotary input Gain control; continuously variable from 125mV to 5V with the input level switch set to low; 1V to 40V with the input level switch set to high
• Crossover Frequency: continuously variable rotary dial; set the low pass crossover point between 50Hz and 200Hz; the crossover slope is 12 dB/octave
• KickEQ Bass Boost: increase the bass level between 0dB and +6dB via the rotary control; centered at 40Hz
