Stays cool under pressure

This reliable and compact KXMA Series rocker will run cool even when pushed hard, thanks to its high-mass heatsink, high-tech internal components, and efficient full-range Class-D amp technology.

Made for marine use

The KXMA800.8 features a conformal-coated circuit board for improved water and dust resistance, plus corrosion-resistant power connections, a gasket-sealed front cover, and stainless steel mounting hardware that won't rust all over your boat's gel coat or carpeting.

Connection perfection

Kicker employs their Fail-Safe Integration Technology (FIT2™) to reject noise and stop any interference generated by your boat's electronics, so you'll enjoy your music clean and pure. Speaker-level inputs make it possible to hook this amp up to almost any stereo receiver or radio. Kicker also helps you set this amp's gain properly, by offering free test tones for downloading. You play a tone and turn the gain up until the gain knob glows red. Then, you turn it down until it just goes out, and the amp's gain is set perfectly.

Versatile controls behind the folding door

A gasket-sealed front door gives you quick and easy access to your amp's controls. You can tune for almost any kind of speaker, as the steeply-sloped high- and low-pass filters offer a wide range of adjustment. The filter sections for the Amp 3 and Amp 4 channels can be set up for bandpass operation — where both the high- and low-pass filters are engaged to allow only the frequencies between them to play — for optimizing the signal for midrange speakers in a 3- or 4-way system.

Product Research

Features

Marine Amplifier: The Kicker KXMA800.8 (48KXMA8008) is an 8-channel marine amplifier, effectively four 2-channel amplifiers built into one chassis (labeled Amp1, Amp2, Amp3 and Amp4). Any pair of channels can be bridged, so it can be configured to power 8-channels, 7-channels, 6-channels, 5-channels, or 4-channels. The KXMA series amps are designed for the marine environment and include ABYC/NMMA-compliant power and ground terminals, anti-corrosive inputs and outputs, gasket protected controls, conformal-coated circuit boards, stainless-steel mounting screws, and a UV-treated aluminum chassis.

Note: Keep in mind, marine amplifiers are not waterproof, and should not be mounted where they will likely get wet.

Class D Amplification: This amp features a Class-D design, efficiently providing ample power in a compact chassis. The power output is as follows:

  • 50 watts RMS x 8 into 4 Ohms (1 kHz, @14.4V, ≤ 1% THD+N)
  • 100 watts RMS x 8 into 2 Ohms (1 kHz, @14.4V, ≤ 1% THD+N)
  • 200 watts RMS x 4 into 4 Ohms bridged (1 kHz, @14.4V, ≤ 1% THD+N)

Controls & Indicators:

  • Input Level: two 2-position switches; select High (speaker-level) or Low (line-level) for Amp1/Amp2 and Amp3/Amp4 independently
  • Fader: three On/Off switches; used to set the number of input channels connected; with all set to Off, the Amp1 input feeds all channels; if switched to On, that amp's input will be independent
  • Auto Turn-on: one 3-position switch:
    • +12V: amp turns on when +12 volts is supplied to the remote (REM) terminal on the amp (preferred method)
    • DC Offset: amp turns on when it sees the DC Offset voltage from a speaker-level input signal (typically the second best option)
    • Audio (Signal Sense): amp turns on when it detects audio from a speaker-level input signal (input gain must be set correctly for this method to work)

      Note: If using either the DC Offset or Audio methods of powering the amplifier On/Off, the REM terminal becomes a +12V output that can be used for activating additional amplifiers.

  • Protection LED (PRT): red Protect LED indicates a problem:
    • Flickering: indicates low-voltage from the battery, either from a low battery or a weak power/ground connection
    • On Solid: indicates overheating, shorted speaker output, or voltage not in the 10-16 volt range
  • Amp1/Amp2 Controls: Amp1 and Amp2 have identical, but independent controls:
    • Input Gain: rotary dial; continuously variable from 125mV to 5V with the Input Level switch set to Low; 250mV to 10V with the Input Level switch set to High; each gain control has an LED backlight to indicate the signal is clipping
    • Crossover Switch: 3-position switch; select Off, High Pass, or Low Pass; the slope is 24dB/octave
    • Frequency: rotary dial; range depends on Frequency Range switch; continuously variable from 10-500 Hz (x1), or 100-5,000 Hz (x10)
    • Frequency Range: 2-position switch; sets the frequency range for the filter to x1 or x10
    • KickEQ+ Bass Boost: rotary dial; increase the bass level between 0dB and +6dB; centered at 40 Hz
  • Amp3/Amp4 Controls: Amp3 and Amp4 also have identical, but independent controls:
    • Input Gain: rotary dial; continuously variable from 125mV to 5V with the Input Level switch set to Low; 250mV to 10V with the Input Level switch set to High; each gain control has an LED backlight to indicate the signal is clipping
    • Crossover Switch: 4-position switch; select Off, High Pass, Low Pass, or Bandpass; the slope is 24dB/octave
    • HP Frequency: rotary dial; continuously variable from 10-500 Hz
    • LP Frequency: rotary dial; range depends on Low-Pass Range switch; continuously variable from 40-500 Hz (x1), 400-5,000 Hz (x10)
    • Low-Pass Range: 2-position switch; sets the frequency range for the low-pass filter to x1 or x10
    • KickEQ+ Bass Boost: rotary dial; increase the bass level between 0dB and +6dB; centered at 40Hz

Wire Connections: The KXMA800.8 has screw-down terminals for the power, ground, turn-on (REM), and speaker outputs. The Power and Ground terminals accommodate up to 4-gauge wire (which Kicker recommends) and the remote and speaker terminals accommodate up to 8-gauge wire. The power and ground terminals are ABYC/NMMA compliant for marine installations.

Fuse: The amplifier doesn't have a fuse on the chassis, therefore a 125-amp fuse must be installed in-line on the power wire next to the battery.

Note: Currently Kicker will extend the standard warranty by an additional year (for a total of three years) when a qualifying Kicker installation kit is purchased with the amplifier.

Input Signal: The amp accepts either high (speaker-level) or low (line-level) voltage input signals on the four pair of RCA inputs, selectable using the input level switches on the side of the amp. When using a speaker-level input signal, add the optional Kicker KiSL speaker-level to RCA adapter (sold separately). The input sensitivity is 0.125-5 volts (low) or 0.25-10 volts (high).

Dimensions:

  • Width: 14.73"
  • Height: 2.19"
  • Depth: 8.43" (8.78" including wire)
