Why Choose Kicker 48KXMA4002 Marine Amplifier?
Marine-Grade Class D Amplifier with KickEQ™ Bass Boost
Designed for harsh marine conditions, this amplifier features REAL MARINE™ construction with anti-corrosive terminals, stainless-steel screws, conformal-coated circuit boards, and ABYC/NMMA-compliant power connections for maximum durability. Its efficient Class D design delivers powerful sound while staying cool and compact, and the adjustable KickEQ™ Bass Boost (0–6 dB at 40 Hz) adds deep, punchy low-end with a simple turn of the knob.
Precision DSP Amplifier with Advanced Tuning
This amplifier features a variable 24 dB crossover for customizable high-pass, low-pass, or band-pass settings, optimizing speaker performance while protecting components. The DSP-controlled preamp ensures clean, distortion-free audio across all frequencies, and the gain control with “Gain Match” LED indicator simplifies setup by showing the optimal input signal.
Marine Amplifier with Protected Controls and Expandable Design
Featuring a gasket-sealed control panel, this amplifier protects crossover, gain, and KickEQ™ settings from moisture while allowing easy adjustments. Full-range RCA outputs simplify adding additional amplifiers without extra wiring, and the black anodized aluminum chassis with a top-mounted teal LED light pipe provides durability and style. Included stainless-steel mounting hardware ensures secure, corrosion-resistant installation in marine environments.
Frequently Asked Questions (FAQ)
- • Why won't the amplifier power on after installation?
Check the battery connection, ground wire, remote turn-on lead, and inline fuse for proper installation. A poor ground or blown fuse is one of the most common reasons the amplifier will not power up.
- • Can this amplifier be installed on a saltwater boat?
Yes. Its marine-grade construction is designed to resist corrosion, moisture, and UV exposure when properly mounted.
- • Why does the amplifier enter protect mode?
Protection mode is typically caused by overheating, a wiring short, or an incompatible speaker load. Verify the speaker impedance and inspect all wiring before restarting the system.
- • Can I bridge the amplifier for a single speaker or subwoofer?
Yes, if the amplifier supports bridged operation and the connected load meets the recommended impedance. Always follow the manufacturer's wiring diagram to avoid damage.
- • Why does the amplifier get hot during extended use?
Some heat is normal when delivering continuous power. Make sure the amplifier has adequate ventilation and is not mounted inside a sealed compartment.
- • Why do I hear engine whine through my speakers?
Ground loops or signal cables routed too close to power wiring can introduce electrical noise. Check the grounding point and separate signal cables from power cables whenever possible.
- • Can I use this amplifier with my factory marine stereo?
Yes. It works with many factory and aftermarket marine head units using compatible audio connections.
- • Why does the sound distort when I raise the volume?
Amplifier clipping, excessive gain, or incorrect crossover settings are common causes of distortion. Proper tuning helps deliver cleaner sound and protects your speakers.
- • Why does the amplifier shut off while playing music?
Low system voltage, overheating, or an overloaded speaker configuration can activate the protection circuit. Check the charging system, cooling airflow, and speaker wiring to resolve the issue.

Set at 4 ohms bridged mode, the amplifier is pushing my 300 watt marine sub louder than eeveer before. The lows are just fantastic with the setup i have now.
