It also has a built-in muting circuit that protects your speakers from loud pops and other audio anomalies.
Frequently Asked Questions (FAQ)
- • Why won't the amplifier turn on after installation?
A blown fuse, poor ground connection, weak battery, or missing remote turn-on signal is usually the cause. Verify the power, ground, fuse, and remote wiring before troubleshooting the amplifier.
- • Can this amplifier power eight marine speakers?
Yes. It is designed to power multiple compatible marine speakers as long as the total speaker impedance stays within the recommended specifications.
- • Why does the amplifier keep entering protection mode?
Protection mode is commonly triggered by overheating, a wiring short, or a speaker load below the recommended impedance. Inspect all wiring connections and allow the amplifier to cool before powering it back on.
- • Is this amplifier suitable for saltwater boating?
Yes. It features marine-grade construction that resists moisture, corrosion, UV exposure, and vibration for long-lasting performance.
- • Why is there power but no sound from one or more channels?
This is often caused by loose speaker wiring, disconnected RCA cables, or incorrect channel configuration. Verify all audio connections and amplifier settings before assuming there is a hardware problem.
- • Why does the amplifier get hot during extended use?
Some heat is expected when operating at high output for long periods. Ensure the amplifier has adequate ventilation and is not mounted inside a sealed compartment.
- • Can I bridge channels to power a subwoofer?
Yes, if the amplifier supports bridged operation and the connected subwoofer meets the recommended impedance requirements. Follow the manufacturer's wiring diagram for the proper bridged configuration.
- • Why do I hear alternator or engine noise through the speakers?
Electrical interference is usually caused by poor grounding or signal cables routed alongside power wiring. Improving the ground connection and separating signal cables from power wires often resolves the issue.
- • Should I install marine-grade wiring with this amplifier?
Yes. Marine-grade power and speaker wire offer superior protection against corrosion, moisture, vibration, and saltwater exposure.
- • Can I expand my marine audio system in the future?
Yes. You can add compatible amplifiers, speakers, or marine subwoofers if your boat's charging system has enough capacity to support the additional equipment.

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.

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!
