Unleash the Waves of Sound!

The Kicker 48KXMA8008 is an 8-channel Class-D marine amplifier that delivers up to 800 watts RMS of power at 2 ohms. It is designed to provide high-quality sound for marine audio systems and is built to withstand harsh marine environments. The KXMA8008 features a conformal-coated circuit board that protects against moisture and dust, and it also has a UV-resistant powder-coated chassis for added durability.

Elevate Your Marine Audio Experience

The KXMA8008 is equipped with a full-range RCA output that can be used to drive additional amplifiers, and it also has a remote level control port for convenient adjustment of subwoofer levels. This amplifier supports bridged and stereo modes, allowing you to configure it to best suit your specific audio setup.

Where Power Meets Precision in Marine Audio Excellence!

Following KICKER Real Marine™ protocol, power terminals meet stringent ABYC/NMMA standards, while thick gasketing protects the control cover from unwanted moisture. Even the aluminum chassis is UV-treated for extra-long life. All KICKER marine amplifiers also utilize conformal-coated circuit boards to protect the heart of the amp from water damage. Overall, the Kicker 48KXMA8008 is a powerful and durable marine amplifier that delivers high-quality sound and offers a range of tuning options for a customizable audio experience.

Fine-Tune Your Marine Sound to Perfection

This amplifier offers a variety of tuning options, including adjustable crossovers, a 6 dB bass boost, and a variable subsonic filter. Additionally, the KXMA8008 features Fail-Safe Integration Technology (FIT2) circuitry, which eliminates noise and interference caused by onboard electronics in marine systems. It also has a built-in muting circuit that protects your speakers from loud pops and other audio anomalies.

FEATURES

Features:

  • Marine-Ready 8-Channel Amplifier: Kicker KXMA800.8 is essentially four 2-channel amps in one chassis, configurable to power 8, 7, 6, 5, or 4 channels. Built for marine environments with ABYC/NMMA-compliant terminals, anti-corrosive inputs/outputs, gasket-protected controls, conformal-coated circuit boards, stainless-steel screws, and UV-treated aluminum chassis. Note: Not waterproof—avoid direct water exposure.
  • Class-D Efficient Power: Compact Class-D design delivers high power efficiently: 50W RMS x 8 at 4Ω, 100W RMS x 8 at 2Ω, or 200W RMS x 4 bridged at 4Ω (@14.4V, ≤1% THD+N).
  • Input Level Selection: Dual 2-position switches allow Amp1/Amp2 and Amp3/Amp4 to select High (speaker-level) or Low (line-level) input.
  • Fader Control: Three On/Off switches let you set the number of input channels connected; Amp1 input can feed all channels if faders are off.
  • Auto Turn-On Options: Three modes: +12V remote (preferred), DC offset from speaker-level input, or signal-sensing audio. Using DC offset or signal-sense makes REM terminal a +12V output for additional amps.
  • Protection LED: Red Protect LED signals issues: flickering = low voltage; solid red = overheating, shorted output, or voltage outside 10–16V.
  • Amp1/Amp2 Controls: Independent rotary gain (Low 125mV–5V, High 250mV–10V) with clipping LED, 3-position crossover (Off/HP/LP, 24dB/oct), frequency dial (10–500Hz x1 or 100–5,000Hz x10), KickEQ+ Bass Boost (+0–6dB at 40Hz).
  • Amp3/Amp4 Controls: Independent rotary gain, 4-position crossover (Off/HP/LP/Bandpass, 24dB/oct), HP/LP frequency dials, low-pass range switch (x1/x10), and KickEQ+ Bass Boost (+0–6dB at 40Hz).
  • Wire Connections: Screw-down power, ground, REM, and speaker terminals. Power/ground up to 4 AWG, REM/speaker up to 8 AWG, ABYC/NMMA compliant.
  • Fuse Requirement: No onboard fuse; install 125A inline fuse near the battery.
  • Input Signal Flexibility: Accepts high (speaker-level) or low (line-level) inputs via four pairs of RCA; optional Kicker KiSL adapter recommended for speaker-level inputs. Sensitivity: 0.125–5V (low) / 0.25–10V (high).
  • Dimensions: Width 14.73", Height 2.19", Depth 8.43" (8.78" including wires).

  • This amp got some serious power! If you got lot of speakers on your boat up to 8 then you won’t have any problems adding up a new amp as it can deliver 100 watts each on its eight channels @ 2 ohms. Its really got some Kick for your boat ride

  • I love the sound quality of this amp. there was a noticeable improvement from my old amplifier. Setting it up with its controls can be a hassle though. As long as you don't have to tweak the controls all the time, then this amp is really such a steal!
