Built for moisture
The Kicker 40KXM400.4 amplifier was built for the harsh marine environment. All exterior connections are gasket sealed to prevent water from entering the amplifier. To prevent damage if water does get in the circuit board has been sprayed with a moisture deterrent conformal coating to prevent damage. All hardware and connections are stainless steel to prevent rust and corrosion. The amplifier chassis is even treated with a UV coating to prevent damage from the sun!
The 40KXM400.4 Marine amplifier is designed to fit virtually anywhere! The optimized circuit board keeps the footprint small and provides the best sound quality. To ensure top audio quality, the 40KXM400.4 uses balanced differential inputs providing the best ability to reject unwanted noise and makes them compatible with any radio. The 40KXM400.4 Amp utilizes class-leading features specific for unbelievable sound in the boating environment.

Amplifiers are power hungry devices that are the heart of every car audio system. A power line fuse on your amp is essential because without one you could have a fire if the power wire is accidentally shorted. We show you how to properly wire a fuse at the battery of your vehicle.
We show you how to set the gains on your amplifiers correctly using an inexpensive oscilloscope. Using the DSO Nano V3, we demonstrate what amplifier clipping looks and sounds like. We then demonstrate how to set your system up the right way and prevent these damaging issues.
