KICKER® PX-Series Amplifiers are full of advanced technology. PX Amplifiers are specially designed to deliver tremendous power in a tiny, weatherproof footprint, all while requiring minimal power from your charging system. Their compact size and efficiency make them perfect for sand-rails, motorcycles, and even jet ski's! With auto turn-on options, built-in crossovers and flexible input styles, KICKER® amps give you the custom sound you need.
Unbelievable power in a tiny package!
PX Amplifiers are no strangers to the KICKER® tradition of compact size. With as much as 500 watts of power, the only thing small about these amps is their footprint. Made to fit nearly anywhere, these miniature power plants start at under five inches in total width.
Whether it's a a car, side-by-sides, motorcycle, or personal water-craft a small amplifier is what you want, but good is it without weatherproofing. The PX-Series amplifiers feature a weatherproof wiring harness, moisture-resistant circuit board and aluminum casing.

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.
